Volcanic eruptions are powerful natural events which impact strongly on society. As human populations grow and expand into volcanically active areas, their exposure and vulnerability to volcanic hazards is also increasing. Of all volcanic hazards, ashfall is the most likely to impact lifelines because of the large areas affected. The widespread dispersal of ash can cause large-scale disruption of vital infrastructure services, aviation, and primary production. Electric power supply is arguably the most crucial of modern infrastructure systems, especially considering the dependence of other sectors on electricity to maintain functionality. During and immediately after ashfalls, electric power systems are vulnerable to a number of impacts, but disruption from volcanic ash-induced insulator flashover (unintended, disruptive electrical discharge) is most common. This thesis investigates the vulnerability of electric power systems to volcanic ashfall by examining impacts to the different sectors of the modern power system and exploring appropriate mitigation strategies. Analogue laboratory trials using a pseudo (synthetic) ash are undertaken to verify the environmental, volcanological and electrical parameters that most affect electrical conductivity and therefore the flashover mechanism in these experiments. While dry ash is highly resistant to the flow of electric current, increasing moisture content, soluble salt load, and compaction (bulk density) will reduce this resistance and, in turn, increase the potential for flashover. Volcanic ash is an acute form of airborne pollution for areas downwind of active volcanoes. Results from laboratory experiments in this thesis suggest that insulator pollution (volcanic ash) performance (dielectric strength) is primarily dictated by (1) the conductivity of the ash, and (2) insulator material, profile (shape) and dimensioning. Composite polymer insulators tested herein effectively minimise sinusoidal leakage current and partial discharge activity and also exhibit higher pollution performance when compared to ceramic equivalents. Irrespective of insulator material, however, the likelihood of flashover increases significantly once the bottom surface of suspension insulator watersheds become contaminated in wet ash. The thesis investigates the vulnerability (hazard intensity/damage ratio) of electric power systems to volcanic ashfall hazards. Identification, analysis, and reduction of the risk of ashfall impacts to power networks is explored as a part of holistic volcanic risk assessment. The findings of the thesis contribute to the readiness, response and recovery protocols for large electric power systems in volcanic disasters; which directly affects the functional operation and economics of industrial and commercial society.

Prescriptively, the requirement of fire safety protection systems for distribution substations is not provided in the compliance document for fire safety to the New Zealand Building Code. Therefore, the New Zealand Fire Service (NZFS) has proposed a list of fire safety protection requirements for distribution substations in a letter, dated 10th July 2002. A review by Nyman [1], has considered the fire safety requirements proposed by the NZFS and discussed the issues with a number of fire engineers over the last three years. Nyman concerned that one of the requirements regarding the four hour fire separation between the distribution substation and the interior spaces of the building may not be necessary when considering the risk exposure to the building occupants in different situations, such as the involvement of the sprinkler systems and the use of transformers with a lower fire hazard. Fire resistance rating (FRR) typically means the time duration for which passive fire protection system, such as fire barriers, fire walls and other fire rated building elements, can maintain its integrity, insulation and stability in a standard fire endurance test. Based on the literature review and discussions with industry experts, it is found that failure of the passive fire protection system in a real fire exposure could potentially occur earlier than the time indicated by the fire resistance rating derived from the standard test depending on the characteristics of the actual fire (heat release rate, fire load density and fire location) and the characteristics of the fire compartment (its geometric, ventilation conditions, opening definition, building services and equipment). Hence, it is known that a higher level of fire safety, such as 4 hour fire rated construction and use of sprinkler system, may significantly improve the fire risk to health of safety of occupants in the building; however, they could never eliminate the risk. This report presents a fire engineering Quantitative Risk Assessment (QRA) on a transformer fire initiating in a distribution substation inside a high-rise residential and commercial mixeduse building. It compares the fire safety protection requirements for distribution substations from the NZFS to other relevant documents worldwide: the regulatory standards in New Zealand, Australia and United States of America, as well as the non-regulatory guidelines from other stakeholders, such as electrical engineering organisation, insurance companies and electricity providers. This report also examines the characteristics of historical data for transformer fires in distribution substations both in New Zealand and United States of America buildings. Reliability of active fire safety protection systems, such as smoke detection systems and sprinkler systems is reviewed in this research. Based on the data analysis results, a fire risk estimate is determined using an Event Tree Analysis (ETA) for a total of 14 scenarios with different fire safety designs and transformer types for a distribution substation in a high-rise residential and commercial mixed-use building. In Scenario 1 to 10 scenarios, different combinations of fire safety systems are evaluated with the same type of transformer, Flammable liquid (mineral oil) insulated transformer. In Scenario 11 to Scenario 14, two particular fire safety designs are selected as a baseline for the analysis of transformer types. Two types of transformer with a low fire hazard are used to replace the flammable liquid (mineral oil) insulated transformer in a distribution substation. These are less flammable liquid (silicone oil) insulated transformers and dry type (dry air) transformers. The entire fire risk estimate is determined using the software package @Risk4.5. The results from the event tree analysis are used in the cost-benefit analysis. The cost-benefit ratios are measured based on the reduced fire risk exposures to the building occupants, with respect to the investment costs of the alternative cases, from its respective base case. The outcomes of the assessment show that the proposed four hour fire separation between the distribution substations and the interior spaces of the building, when no sprinkler systems are provided, is not considered to be the most cost-effective alternative to the life safety of occupants, where the cost-benefit ratio of this scenario is ranked fifth. The most cost-effective alternative is found to be the scenario with 30 minute fire separation and sprinkler system installed. In addition to the findings, replacing a flammable liquid insulated transformer with a less flammable liquid insulated transformer or a dry type transformer is generally considered to be economical alternatives. From the QRA analysis, it is concluded that 3 hour fire separation is considered to be appropriate for distribution substations, containing a flammable liquid insulated transformer and associated equipment, in non-sprinklered buildings. The fire ratings of the separation construction can be reduced to 30 minute FRR if sprinkler system is installed. This conclusion is also in agreement with the requirements of the National Fire Protection Association (NFPA).

驅逐黑暗、迎來光明，是變電所最重要的任務，但它往往被歸類為鄰避設施，不為使用者所接受。變電所引發的風險疑慮，無論是環境、健康等，儘管尚無法以科學實證其因果關係，卻深深烙印人心；加上不甚透明且缺乏參與機制的規劃方式，致使變電所選址過程抗爭不斷。 現代社會可說是充滿風險的社會，也就是德國學者貝克所謂的「風險社會」。風險不分階級、貧富，充斥在我們身旁，引發無聲且無形的恐懼。高科技雖然帶來生活便利，但也帶來前所未有的新風險—科技風險。既然風險是現代社會非常重要且切身的課題，如何以風險的視角來解構變電所選址過程，便成為本文的論述主軸。 現行變電所用地之規劃方式，主要是依據都市計畫(土地使用管制)及電力負載預測結果來選擇變電所設置地點；變電所用地的使用項目與內容，則取決於是否辦理多目標使用。然而，土地使用管制之僵固性及電力負載預測結果的不確定性卻造成變電所選址過程必須面臨規劃方式、民眾抗爭、風險分配等三方面困境，使得變電所選址困難重重。 規劃部門、電力公司與民眾能否「共同面對」變電所選址在規劃方式、民眾抗爭、風險分配等三方面的困境，尋求變電所土地使用管制內容再定位並融合民眾參與機制（儘管民眾參與並非萬能），使變電所選址過程掙脫規劃方式的枷鎖，將是降低變電所選址抗爭且形成風險分配共識的必要方向，也才是風險社會中變電所選址的最佳出路。 / The primary function of a substation is to expel the darkness and usher in light. However, it is usually classified as NIMBY facilities and not welcomed by public. People are constantly worried and even feared by nearby substations, although there is neither scientific evidence to prove that substations are harmful nor directly caused any disease. Moreover, substation siting procedure is less transparent and lack of participatory mechanisms during the planning stage, resulting in protests against substation during the siting process. Modern society is full of risks as described by German sociologist Dr. Ulrich Beck in “Risk society.” Risks are around us all the times, regardless of class or wealth. It creates silent and invisible fears. Modern high-tech life style provides convenience but technology also brings unprecedented new risks - technological risks. Since technological risk is an important issue and it can affect anyone in modern society, this article will discuss the risks involved by deconstructing the substation siting procedure. The existing substation siting models are based on the designation of urban plan and the results of power load forecast; the land-use projects of substation are depended on the content of multi-objective land-use. The rigidity of zoning and the uncertainty of power load forecast results plight in substation siting procedure at three situations: approach to planning, public protests and risk allocation, also makes substation siting much difficult. Although public participation is not the magic bullet, substation siting zoning restriction can be unlocked by combining public participation with land use re-position. The best approach to prevent protest against substation siting process and reach consensus in risk distribution is to have planning departments, power companies and the community seeking solution together.

This thesis presents how experimental results, from wave power research performed offshore at the Lysekil research site, were obtained. The data were used to verify theoretical models as well as evaluate the feasibility of wave power as a future sustainable energy source. The first experiments carried out at the research site was the measurement of the force in a line where one end was connected to a buoy with a diameter of 3 m and the other end to a set of springs with limited stroke length. The system is exposed to high peak forces compared to average forces. The maximum measured force in the line, when the buoy motion is limited by a stiff stopper rope is ten times the average force in that particular sea state. The experiment performed on the first wave energy converter tested at the Lysekil Research Site is described. The infrastructure of the site is presented where the central connection point is the measuring station. The key finding is that it is possible to transform the motions of ocean waves into electrical energy and distribute it to land. Many wave energy converters must be interconnected if large amounts of energy are to be harvested from the waves. The first submerged substation intended for aggregation of energy from wave power converters is described, with focus on the measurement and control system placed inside the substation. During this experiment period the generators were equipped with many different sensors; these measurements are explained in the thesis. The system that aggregates power from the studied wave energy converter is regularly exposed to peak power of up to 20 times the maximum average output from the converter. Vertical and horizontal movement of the buoy has been measured in different ways. The result is that the vertical displacement of the buoy can be measured with a simple accelerometer circuit but it is much more complicated to measure the horizontal displacement. A special method for measuring the horizontal displacement has been implemented by measuring the strain in the enclosure and the force in the line. / Den här avhandlingen berättar om hur experimenten vid Lysekils forskningsområde för vågkraft har utförts.

IEC 61850 is rapidly becoming the internationally recognized standard for substation automation systems making it an indispensable element in power system protection and automation education. In order to facilitate teaching this very practical subject, a laboratory setup was developed to demonstrate IEC 61850 station bus inter Intelligent Electronic Device (IED) communication. In this setup, an electrical substation was implemented in a real time digital simulator (RTDS) and protection schemes were implemented in IEC 61850 station bus compliant IEDs from different vendors. Trip signals and breaker statuses were exchanged between RTDS and IEDs using GOOSE (Generic Object Oriented Substation Event) messages. Several protection applications including a novel backup bus protection scheme were developed based on the setup to demonstrate the use of GOOSE messages in time critical applications. The developed test setup along with the designed laboratory exercises will undoubtedly enhance teaching, training and research in this important field. / February 2016

Kungälv Energi äger och ansvarar idag över Kungälv Kommuns elnät. Med en ökande befolkningsmängd ställs allt högre krav på elnätet och framför allt leveranssäkerheten. Med kalla vintrar och stort energibehov ger detta upphov till en svårare situation gällande leveranssäkerhet. I nuläget har Kungälv Energi två mottagarstationer, en 130/10kV-station espektive 130/20kV-station. 30/10kV-stationen börjar närma sig en gräns där effektbehovet närmar sig den maximala istributionskapaciteten. Därför fastställs en plan för att kunna klara av effektbehovet vid averi på en av två 130/10kV-transformatorer i mottagarstationen M1. Resultatet av rapporten visar att tillräcklig kapacitet finns i närliggande fördelningsstationer för att klara av reservdrift under hög belastning utan att några övriga komponenter skadas. Rapporten behandlar främst effektflöden för att kontrollera att dessa ej överskrider transformatorernas, ledningarnas och kablarnas märkeffekt. I flertalet fall har även faktorer för nödbelastning räknats med vilket resulterar i att samtliga linjer hos Kungälv Energi klarar av den ökade belastningen. Upptäckta flaskhalsar i nätet har uppmärksammats och delgetts samt förslag till förändringar för att förhindra framtida problem. / Kungälv Energi owns and is responsible of Kungälv municipality's electricity grid. With an increasing population and increasing demands on the grid and especially security of supply. With cold winters and large energy gives rise to a more difficult situation regarding security of supply. Currently, Kungälv Energi two receiving stations, a 130 / 10kV station and 130 / 20kV station. 130 / 10kV station is approaching a point where power demand is approaching the maximum distribution capacity. Therefore sets out a plan to cope with the power demand at the failure of one of two 130 / 10kV transformers of the receiving station M1. The results of the report shows that sufficient capacity is available in nearby distribution stations to cope with the emergency operation under high loads without any other components damaged. The report deals primarily with power flows to check that they do not exceed transformers, lines and cables rated power. In the majority of cases have also factors for distress load been counted with, which gives the result that all lines of Kungälv Energi can handle the increased load. Detected bottlenecks in the network have been highlighted, communicated and proposed changes to Kungälv Energi to prevent future problems.

Depuis son invention, l'électricité joue un rôle essentiel dans notre vie quotidienne. L'apparition des premières installations de production d'électricité à la fin du XIXème siècle a ouvert la voie au système électrique et à ses sous-systèmes. Les consommateurs d'énergie électrique exigent un service fiable en termes de stabilité et de sécurité du réseau électrique. Depuis la libéralisation des marchés, les producteurs d'énergie électrique, les fournisseurs de services publics et d'équipements, en tant qu'acteurs principaux, suivent une tendance émergente pour satisfaire les demandes des consommateurs. Cette tendance implique l'amélioration des technologies, l'innovation et le respect des normes et des réglementations gouvernementales. Tous ces efforts ont été qualifiés de concept de réseaux intelligents (Smart Grid en anglais) qui évolue pour répondre aux demandes futures.Les sous-stations numériques modernes et futures façonnent des nœuds essentiels dans le réseau électrique, où la stabilité du flux d'énergie électrique, la conversion des niveaux de tension et la protection de l'équipement du poste de commutation figurent parmi les principaux rôles de ces nœuds. La norme prometteuse CEI 61850 et ses composants apportent de nouvelles fonctionnalités aux systèmes d'automatisation des postes. L'utilisation de la communication Ethernet dans ces systèmes réduit la quantité de connexions câblées qui réduit l'encombrement de l'équipement de la sous-station, des dispositifs et de leur câblage.L'intégration des nouvelles fonctionnalités CEI 61850 au niveau des sous-stations requiert des compétences multidisciplinaires. Par exemple, considérons les tâches de protection et de contrôle de la puissance d'un côté et les technologies de l'information et de la communication de l'autre. La dépendance entre les fonctions d'automatisation des sous-stations et les réseaux de communication à l'intérieur d'une sous-station pose de nouveaux défis aux concepteurs, intégrateurs et testeurs. Ainsi, étudier la fiabilité des fonctionnalités du système, par exemple, les schémas de protection, exige de nouvelles méthodes d'essai où les méthodes conventionnelles ne sont pas applicables. Les nouvelles techniques devraient fournir des moyens d'évaluer les performances des systèmes conçus et de vérifier leur conformité aux exigences des normes.Afin d'améliorer la fiabilité du système conçu, ce travail vise à développer des méthodes pour tester les systèmes d'automatisation de sous-station CEI 61850, en particulier sur les processus et les niveaux de la baie, dans une plate-forme dédiée aux tâches de recherche. Cette plate-forme incorpore des dispositifs de pointe et des cartes de test qui aideront à observer simultanément les interactions dynamiques des transitoires de puissance et les perturbations du réseau de communication. Les données obtenues lors des tests expérimentaux seront utilisées pour diagnostiquer les défaillances et classer leurs causes afin de les supprimer et d'améliorer la fiabilité du système conçu. / Since its invention, Electricity has played a vital role in our everyday life. The appearance of the first power production facilities in the late nineteenth century paved the way for the electrical power system and its subsystems. Consumers of electric power demand dependable service in terms of power grid stability and safety. Since the liberalization of the markets, producers of electric power, utilities and equipment suppliers, as principal players, are following an emerging trend to satisfy consumers’ demands. This trend involves improving technologies, innovating and respecting standards requirements and governments’ regulations. All these efforts termed as the concept of the Smart Grid that is evolving to meet future demands.Modern and future digital substations shape essential nodes in the grid, where stability of electric power flow, converting of voltage levels and protecting switchyard equipment are among the primary roles of these nodes. The promising standard IEC 61850 and its parts, bring new features to the substation automation systems. The use of Ethernet based communication within these systems reduces the amount of hardwired connections that results in lowering footprint of substation equipment, devices and their cabling.Integration of the new IEC 61850 features at the substation levels requires multidiscipline competences. For instance, consider power protection and control tasks from one side and information and communication technologies from the other side. Dependency between substation automation functions and communication networks inside a substation brings new kinds of challenges to designers, integrators and testers. Thus, investigating the dependability of the system functionalities, e.g. the protection schemes, requires new methods of testing where conventional methods are not applicable. The new techniques should provide means to evaluate performance of designed systems and checking their conformance to the standards requirements.In order to improve the designed system dependability, this work aims to develop methods for testing the IEC 61850 enabled substation automation systems, especially on the process and the bay levels, in a platform dedicated for research tasks. This platform incorporates state-of-art devices and test-set cards that will help to simultaneously observe dynamic interactions of the power transients and communication network perturbations. Data obtained during the experimental tests will be used for diagnosing of failures and classifying their causes in order to remove them and enhance dependability of the designed system.

Un système de distribution électrique est le cœur de tous types de sites industriels, aussi bien les sites producteurs d'énergie que les sites consommateurs. La sécurité de ce système doit être impérativement assurée par la mise en place des unités assurant plusieurs fonctionnalités de protection contre les dédauts électriques. Parmi ces fonctionalités il existe celles qui se basent sur des échanges d'information entre plusieurs unités de protection. Le standard IEC 61850 guarantit cet échange des informations via des signaux ‘temps réel' échangé via le réseau de communication. Vue l'aspet non deterministe de ces signaux, une étude poussée de leur fiabilité doit être effectuée. Pour ces raisons notre travail de thèse a pour objectif de mettre en place une méthodologie, basée sur une plateforme de Co-Simulation conçue pendant notre étude, qui permet la validation de la fiabilité de ces messages tout au long du cycle de vie d'un système de communication IEC 61850. / From 2004, a new worldwide standard of communication IEC61850 is introduced in the majority of substation automation system carrying out new innovation prospects to the world of substation. One of these feature is that it allows the exchange of security real time communication messages all over the communication network. These messages are used as control information for the Distributed Automation Application 'DAA'. Taking into consideration that DAA have a direct effect on ythe dependability of a smart grid architecture, the fiability of these real time IEC 61850 should be evaluated. For these reasons, our research delas with the development of a Co-Simulation platform that permits the evaluation and validation of an IEC 61850 communication network.

A geração de manobras é normalmente manual e a sua elaboração pode demorar de uma hora e a um dia, dependendo da sua complexidade e do número de equipamentos envolvidos. O pouco tempo para a geração das manobras, principalmente em situações de contingência, aumenta a probabilidade de ocorrência de erros nas manobras elaboradas. Os fatores relacionados à demora na geração, às falhas na análise dos efeitos da manobra na rede elétrica e à alta susceptibilidade de erros, podem afetar negativamente o sistema elétrico e a companhia elétrica, diminuindo a segurança no sistema e aumentando as perdas monetárias associadas principalmente à indisponibilidade de equipamentos e à interrupção do fornecimento de energia. Este trabalho propõe uma nova abordagem para a geração automática de manobras para sistemas eletroenergéticos. Esta abordagem tem as principais características de uma solução ideal para o problema: (i) se baseia na topologia de tempo real da rede elétrica; (ii) usa regras de intertravamento baseadas na configuração topológica da rede e nos princípios elétricos dos dispositivos, garantindo assim a segurança do sistema e do pessoal da companhia elétrica; e (iii) usa algoritmos genéricos que independem dos tipos de arranjos topológicos, bem como do número de equipamentos na subestação. Para verificar a corretude da solução no escopo de uma companhia elétrica real, as manobras geradas automaticamente são comparadas às manobras padrão elaboradas manualmente pelos operadores e/ou supervisores da Companhia Hidroelétrica do São Francisco (CHESF). Ao todo, mais de 1300 roteiros foram comparados. Para a liberação de disjuntor, o percentual de acerto foi de 91,1%; e para a normalização de disjuntor, o percentual de acerto foi de 90,4%. A mediana dos tempos de geração automática destas manobras foram de 14ms e 16ms para liberação e normalização de disjuntor, respectivamente. Estes tempos apontam ganho significativo no tempo gasto para a geração de uma manobra. A outra forma de validação da técnica proposta baseia-se em um sistema prova-de-conceito (SmartSwitch). Esse sistema se destina aos operadores e supervisores da CHESF. Um grupo selecionado de especialistas na geração de manobras é responsável pela avaliação da usabilidade do sistema SmartSwitch e da corretude das manobras geradas automaticamente. A avaliação inicial feita por este grupo mostra que a técnica é capaz de gerar, em situações normais de topologia, operações de seccionamento corretas e seguras do ponto de vista elétrico. Percebeu-se também alto nível de aceitação do sistema SmartSwitch por parte dos operadores e supervisores de operação da CHESF, o que prova a contribuição do sistema para a eficácia do processo de geração de manobras na companhia colaboradora. / Switching sequences executed in the electrical grid aim to prevent electric power provision interruptions, which may be caused by random events, such as equipment faults or overloads; or equipment maintenance. Switching sequence generation is usually manual, and can last between one hour and one day, according to the switching sequence complexity and the number of equipment involved. The limited time for switching sequence generation, especially in contingency circumstances, increases the probability of errors in the resulting switching sequences. Factors such as delay in switching sequence generation, failure in analyzing the switching sequence's effects on the electrical grid, and susceptibility to errors can negatively affect the electric system and the electric power company, decreasing system security, and increasing monetary losses mainly associated with equipment unavailability and electric power provision interruption. This study presents and evaluate a new approach for automatically generating switching sequences in electric substations; the proposal possesses the main characteristics to ideally solve the problem. The technique, for automatically generate switching sequences, (i) is based on the power grid's real-time topology; (ii) uses interlocking rules based on the grid's topological configuration in order to guarantee security for the system and for the workers; (iii) uses algorithms that are independent of the equipment's topological disposition and the substation's size. To verify the correctness of solution in the scope of a real electric company, the automatically generated switching sequences was compared to standard switching sequences made manually by CHESF operation supervisors or operators. In ali, more the 1300 scripts were compared. For switching sequences to release circuit breaker during maintenance periods, the percentage of correct switching sequence was 91,1%; and for switching sequence to restore circuit breaker, the percentage of correct switching sequence was 90,4%. The execution time was 14ms and 16ms, respectively. The second validation stage is based on proof-of-concept system, named SmartSwitch. The system is presented in this work and is intended to be used by CHESF operation supervisors and operators. A selected group of specialists in switching sequence generation is responsible for evaluating the system regarding its usability and correctness. The initial evaluation made by specialists group showed that technique is able to generate, in normal topology, correct and safe switching operations from electric point of view. Also, it was noticed that the tool has a high levei of acceptance by the company's operators and supervisors, due to its low maintenance needs.

This thesis explore the possibility to automate a process for configuration of secondary substations monitoring and control. By using a network information system (NIS), information of secondary substations can be extracted, such as feeder naming, primary equipment type, rating and model. From this information an automated process of configuring the secondary substation is possible, which open up the possibility to cost-efficiently digitalise the distribution grid. In the project, the standard IEC 61850 for configuration of communications of intelligent electrical devices was used to automate and standardize the process. The process starts with a extracted IEC 61970 CIM file from the NIS. The IEC 61970 CIM file is converted into a IEC 61850 SCL file through an system engineering tool. The configuration is based of information from the NIS, where the models and types of the equipments decides what type of functionality that is needed for the secondary substation. With help of the created SCL file hardware and human-machine interface (HMI) was configured, creating a full functional system for the secondary substation monitoring and control equipment. The usage of 400V capable input module together with bus couplers, configured in IEC 61850, lowers the configuration needed for the hardware. The usage of SCL files also helps automate the creation of HMI for the secondary substation through IEC 61850 based tools in SCADA software. Creating views of both single-line diagrams as well as digital representation of the secondary substation outgoing feeders with measured values on display. The result of the project helps show NIS information is sufficient and standards mature enough to allow an almost fully automated system. Lowering the total time spent on each stations configuration to around two hours. Leading the way for future development of automating software for configurations of the secondary substations.
