This study takes advantage of wide area measurements to propose a centralized nonlinear controller that acts on power system stabilizers, to cooperatively increase the damping of problematic small signal oscillations all over the system. The structure based on decision trees results in a simple, efficient, and dependable methodology that imposes much less computational burden than other nonlinear design approaches, making it a promising candidate for actual implementation by utilities and system operators. Details are given to utilize existing stabilizers while causing minimum changes to the equipment, and warranting improvement or at least no detriment of current system behavior. This enables power system stabilizers to overcome their inherent limitation to act only on the basis of local measurements to damp a single target frequency. This study demonstrates the implications of this new input on mathematical models, and the control functionality that is made available by its incorporation to conventional stabilizers. In preparation of the case of study, a heuristic dynamic reduction methodology is introduced that preserves a physical equivalent model, and that can be interpreted by any commercial software package. The steps of this method are general, versatile, and of easy adaptation to any particular power system model, with the aggregated value of producing a physical model as final result, that makes the approach appealing for industry. The accuracy of the resulting reduced network has been demonstrated with the model of the Central American System. / Ph. D.

Monitoring and protection of power systems is a task that has manifold objectives. Amongst others, it involves performing data mining, optimizing available resources, assessing system stresses, and doing data conditioning. The role of PMUs in fulfilling these four objectives forms the basis of this dissertation. Classification and regression tree (CART) built using phasor data has been extensively used in power systems. The splits in CART are based on a single attribute or a combination of variables chosen by CART itself rather than the user. But as PMU data consists of complex numbers, both the attributes, should be considered simultaneously for making critical decisions. An algorithm is proposed here that expresses high dimensional, multivariate data as a single attribute in order to successfully perform splits in CART. In order to reap maximum benefits from placement of PMUs in the power grid, their locations must be selected judiciously. A gradual PMU placement scheme is developed here that ensures observability as well as protects critical parts of the system. In order to circumvent the computational burden of the optimization, this scheme is combined with a topology-based system partitioning technique to make it applicable to virtually any sized system. A power system is a dynamic being, and its health needs to be monitored at all times. Two metrics are proposed here to monitor stress of a power system in real-time. Angle difference between buses located across the network and voltage sensitivity of buses lying in the middle are found to accurately reflect the static and dynamic stress of the system. The results indicate that by setting appropriate alerts/alarm limits based on these two metrics, a more secure power system operation can be realized. A PMU-only linear state estimator is intrinsically superior to its predecessors with respect to performance and reliability. However, ensuring quality of the data stream that leaves this estimator is crucial. A methodology for performing synchrophasor data conditioning and validation that fits neatly into the existing linear state estimation formulation is developed here. The results indicate that the proposed methodology provides a computationally simple, elegant solution to the synchrophasor data quality problem. / Ph. D.

O termo sustentabilidade corporativa refere-se à capacidade de uma organização de sobreviver no longo prazo, mantendo-se (minimamente) lucrativa para que possa exercer suas atividades com cada vez menos impactos negativos ambientais e mais benefícios sociais. Considerando a lógica de que a empresa é aquilo que ela é capaz de mensurar, organizações sustentáveis demandam sistemas gerenciais de mensuração de desempenho que estejam alinhadas ao desenvolvimento sustentável. Assim, o presente estudo se propõe a discutir a seguinte pergunta de pesquisa: Como é inserida a sustentabilidade nos sistemas de mensuração de desempenho corporativos? Para isso, são propostos dois objetivos de pesquisa: (i) levantar os sistemas de mensuração de desempenho de sustentabilidade e explorar seus principais desafios; e (ii) explorar a importância relativa dada pelas empresas em relação aos indicadores de sustentabilidade. Para isso, a pesquisa conta com uma revisão sistemática da literatura e estudos de casos multissetoriais (um piloto e quatro exploratórios). A pesquisa traz evidências de que a temática de indicadores de sustentabilidade é ainda incipiente e pouco estruturada, com potencial de melhorar o aproveitamento da literatura já consolidada de sistemas de mensuração de desempenho. O estudo bibliométrico conta com (i) estatística descritiva, (ii) análise de redes de relacionamento (co-citação e palavras-chave) e (iii) análise de conteúdo a partir de uma amostra de artigos extraídos da base de dados ISI Web of Knowledge (Web of Science). Verifica-se que a literatura de indicadores de sustentabilidade aborda temáticas diversas, tais como vantagem competitiva, gestão de stakeholders e avaliação do ciclo de vida. Já os estudos de casos baseados em entrevistas semi-estruturadas permitiram o levantamento dos seguintes sistemas de mensuração de desempenho com incorporação de indicadores de sustentabilidade: sistema de avaliação de desempenho das áreas, sistema de avaliação de desempenho individual, indicadores para elaboração de relatórios internos e externos e sistema de avaliação inicial de projetos. Além disso, foram identificados fatores que interferem na prioridade dos indicadores de sustentabilidade: estratégia corporativa, pré-requisito; maturidade da questão e urgência. Dentre os desafios apontados pelas empresas, encontram-se a definição de indicadores para avaliar os benefícios sociais decorrentes das atividades da organização, a quantificação monetária de retorno de iniciativas ambientais e sociais e o engajamento dos colaboradores na sustentabilidade corporativa, independente da natureza das suas atividades. A pesquisa mostra que há benefícios na incorporação da sustentabilidade no sistema de mensuração de desempenho corporativo e que isso ainda tem potencial para ser abordado de forma mais sistemática, sem depender exclusivamente da iniciativa de determinados líderes. O papel desses atores para implantação de práticas sustentáveis na organização é fundamental e necessário, mas não suficiente, já que a sustentabilidade corporativa depende do engajamento de diversos stakeholders (internos e externos à organização), que podem ser influenciados pela cultura e pelos processos de negócios alinhados à lógica do desenvolvimento sustentável. / The term corporate sustainability refers to the ability of an organization to survive in the long term, keeping itself (minimally) profitable in order to conduct their activities with less negative environmental impacts and more social benefits. Whereas the logic that the company is what it is capable of measuring, sustainable organizations require performance management systems that are aligned to sustainable development. Thus, this study aims to discuss the following research question: \"How sustainability is embedded in corporate performance measurement systems?\" For this, it proposes two research objectives: (i) identify the sustainability performance measurement systems and explore their major challenges, and (ii) explore the relative importance given by companies in relation to sustainability indicators. So, the research has a systematic literature review and multisectoral exploratory case studies (one pilot and four exploratory). The research provides evidence that the theme of sustainability indicators is still incipient and unstructured, with the potential to improve the use of literature already consolidated on performance measurement systems. The bibliometric study is based on (i) descriptive statistics, (ii) analysis of extracted networks of relationships (co-citation and keywords) and (iii) content analysis of a given sample of articles extracted from ISI Web of Knowledge (Web of Science). It is found that the literature of sustainability indicators covers different topics such as competitive advantage, stakeholder management and life cycle assessment (LCA). The cases studies based on semi-structured interviews allowed the identification of the following performance measurement systems that incorporate sustainability indicators: performance evaluation of the areas; individual performance evaluation system; indicators for internal and external reports; and initial project evaluation system. In addition, factors influencing the priority of sustainability indicators have been identified: maturity of the issue, requirement, corporate strategy and urgency. Among the challenges faced by companies, there are the definition of indicators to assess the social benefits of the organization activities, the quantification of the monetary return of environmental and social initiatives and employee engagement in corporate sustainability, independently of the nature of their activities. Research shows that there are benefits in incorporating sustainability in corporate performance measurement system and it still has the potential to be addressed more systematically, without relying solely on the initiative of certain leaders. The role of these actors for implementing sustainable practices in the organization is essential and necessary, but not sufficient, since the corporate sustainability depends on the engagement of various stakeholders (internal and external to the organization), which may be influenced by the culture and the business processes aligned to the logic of sustainable development.

Atualmente, estes sistemas compõem as chamadas smart grids, redes inteligentes de geração, transmissão e distribuição de energia, dotadas de dispositivos de comunicação de dados, possibilitando a aplicação de sistemas distribuídos, com base na troca de informações entre equipamentos, formando uma nova rede, também de alta complexidade, para interligação e controle de dados. No Brasil, um trabalho inédito vem sendo desenvolvido na criação deste tipo de rede: a utilização de uma infraestrutura avançada de medição, baseada em sistemas de medição centralizada, alocadas em áreas de grandes concentrações urbanas, com objetivos de diminuição, ou até mesmo eliminação de perdas comerciais de distribuição de energia, emerge como novidade na aplicação de redes inteligentes de distribuição de energia elétrica no país. Este trabalho tem por objetivo a descrição do desenvolvimento de uma solução computacional, baseada em um método de busca metaheurística conhecido como Simulated Annealing para apoio à formulação de projetos de redes otimizadas de infraestrutura avançada de medição que utilizam equipamentos de sistemas de medição centralizados em uma rede de distribuição de energia elétrica, garantindo máxima cobertura da rede, atendimento a todos os clientes geograficamente localizados na região de projeto, minimizando custos de instalação dos sistemas. Na busca deste objetivo, este trabalho apresenta a redução do problema de otimização para o Problema do Recobrimento, a construção do modelo matemático, a implementação computacional e as aplicações na forma de simulações e resultados. A metodologia proposta, aplicada ao sistema computacional como forma de simulação, permite uma análise muito rápida e dinâmica de topologias de rede a serem projetadas para utilização em projetos de redes de comunicações, onde se utilizam sistemas de medição centralizados. O sistema computacional permite a alteração das características de simulação e das características das redes, dependendo das restrições impostas pela área geográfica em estudo. A estratégia apresenta bons resultados na formação de topologias de redes de comunicação para sistemas de medição centralizada, bem como otimização na utilização de equipamentos, reduzindo custos de instalação na rede. / Centralized systems of energy measurement are actually a choice for automating networks and ensure the operation of the complex system of electricity distribution. Currently, these systems comprise the so-called smart grid generation, transmission and distribution of energy, equipped with data communication devices, enabling the implementation of distributed systems, based on the exchange of information between devices, forming a new network, of high complexity, and for interconnection data control. In Brazil, a new work is being developed for creating this type of network: the use of an advanced infrastructure for measurement, centralized measurement systems allocation in areas of large urban concentrations, with goals of reducing, or even eliminating, commercial losses of power distribution, that emerges as a novelty in applying smart grid distribution of electricity in the country. This work aims at describing the development of a computational solution, based on a metaheuristic search method known as Simulated Annealing to support the design of optimized network for advanced metering infrastructure using equipment measurement systems on a centralized network of power distribution, ensuring maximum coverage, service to all customers geographically located in the area and minimizing installation costs of the systems. In pursuit of this goal, the work presents the reduction of the optimization problem to the covering problem, the mathematical model construction, computational implementation and application in the form of simulations and results. The methodology applied to the computing system like a simulation, allows an very fast and dynamic analysis of the network topologies to be designed for use in projects where communication networks are used in centralized measurement systems. The computing system allows modification of simulation features and characteristics of networks, depending on the constraints imposed by the geographical area under consideration. The strategy presents good results in the formation of network topologies communication systems for centralized measurement and optimizing the use of equipment, reducing installation costs in the network.

This diploma thesis deals with finding the minimal countercurrent distance of the water surface sensors used in practice for use with a V-notch weir. The thesis complements the previously obtained results of measurements in the longitudinal vertical plane of symmetry of the inlet channel with measurements on the whole countercurrently located plane of the inlet channel. The measurements are obtained experimentally in the water management research laboratory at the Department of the Water Structures Faculty of Civil Engineering in Brno. Measurements on each individual weir with top angle cutouts of 90°, 53°8´ and 28°4´ are taken at five possible positions of the sensor towards the plane of the measuring weir. All measurements are also repeated for three different vertical distances between the lowest level of the spillway edge and the bottom of the inlet channel. The obtained data are evaluated and subsequently the minimal distances for the location of the water surface sensor in front of a counter weir is determined. The thesis also includes recommendations for practical application presented in the form of text, tables and also graphically.

I en allt mer konkurrenskraftig och snabbt föränderlig miljö måste dagens organisationer identifiera sina befintliga positioner, klargöra sina mål samt fungera mer effektivt och ändamålsenligt. Dessa premisser gäller också för icke vinstdrivande organisationer som även de behöver anpassa sig efter denna nya verklighet för att överleva. Ett prestationsmätningssystem (PMS), som sammanfattningsvis är ett redskap för att säkerställa att organisationer uppfyller sina mål och sitt syfte, kan hjälpa till att klara av dessa utmaningar. Det finns dock studier som visar att chefer och uppdragsgivare i icke vinstdrivande organisationer är allt mer oroliga över att mäta och hantera organisatoriska prestationer. Studien syftar till att förklara och bidra till en större förståelse av användningsområden och syften med PMS i icke vinstdrivande organisationer. Således blir också syftet med studien att bidra till den befintliga kunskapsbasen inom PMS. Denna kvalitativa fallstudie är utförd på Systembolaget och har primärt samlat in empiriska data genom semistrukturerade intervjuer med sju chefer från tre hierarkiska nivåer i ett av organisationens försäljningsdistrikt, men även genom dokument. Genom analys och diskussion av det empiriska materialet i förhållande till den teoretiska referensramen har vi dragit slutsatserna att ändamålet med PMS är densamma för icke vinstdrivande organisationer som för vinstdrivande organisationer. Vi har identifierat PMS som ett managementverktyg för efterlevnad och utveckling av strategier samt nå mål och visioner. Studien visar även att ett strategiskt sammanpassat PMS med fokus på icke-finansiella mått tydligt kopplade till verksamheten, kan ha betydelse för översättningen av icke vinstdrivande organisationers strategi till ett önskvärt handlingssätt och resultat. / An increasingly competitive and quickly changing environment requires today’s organizations to clarify their goals, identify their existing positions, and function more efficiently and effectively. These premises also apply to nonprofit organizations that also need to adapt to this new reality to survive. A performance measurement system (PMS) that, in short terms, is a tool for ensuring that organizations meet their goals and purposes can help to cope with these challenges. However, studies shows that measuring and managing organizational performance is an increasing concern for managers and constituents in nonprofit organizations. The purpose of the study is to explain and contribute to a greater understanding of the use and purpose of PMS in nonprofit organizations. Thus, the purpose of the study will also be to contribute to the existing knowledge base within the field of performance measurement. This qualitative case study is conducted on Systembolaget and has collected empirical data primarily through semi-structured interviews with seven managers from three hierarchical levels in one of the organization's sales districts, but also through documents. Through an analysis and discussion of our empirical findings in relation to our theoretical framework, one of the conclusions is that the purpose of PMS is the same in nonprofit organizations as for profit-making organizations. We have identified PMS as a management tool for adherence and development of strategies as well as achieving goals and visions. The study also shows that a strategically aligned PMS focusing on nonfinancial measures clearly linked to operations can be important when it comes to translation of nonprofit organization's strategy into desirable actions and results.

In the early 1980s, relaying engineers conceived a technology allowing a huge step forward in the monitoring of power system behavior: the synchrophasor, i.e. the estimation of a phasor representation - amplitude and phase - of a sinusoidal waveform at a given point in time thanks to highly accurate time synchronization of a digital relay. By measuring synchrophasors across the power system several times per second, and centralizing the appropriate information in a hierarchical way through a telecommunication network link, it is now possible to continuously monitor the state of very large systems at a high refresh rate. <p><p>At the beginning, the phase angle information of synchrophasors was used to support or improve the performance of classic monitoring applications, such as state estimation and post-mortem analysis. Later, synchrophasors were found to be valuable for the detection and analysis of phenomena that were not monitored previously, such as system islanding and angular stability. This allows a better understanding of system behavior and the design of remedial actions in cases where system security appears to be endangered. Early detection and even prediction of instabilities, as well as validation and improvement of the dynamic models used for studies, have thus become possible.<p><p>However, a power system is rarely stationary and the assumptions behind the definition of “phasor” are not completely fulfilled because the waveforms' frequency and amplitude are not constant over a signal cycle at fundamental frequency. Therefore, accuracy of synchrophasor measurements during dynamic events is an important performance criterion. Furthermore, when discontinuities (phase jumps and high magnitude variations) and harmonics disturb the measured analog signals as a consequence of switching actions or external disturbances, measurements provided to the “user” (the operator or the algorithms that will take decisions such as triggering alarms and remedial actions) require a certain robustness. <p><p>The efforts underpinning this thesis have lead to the development of a method that ensures the robustness of the measurement. This scheme is described and tested in various conditions. In order to achieve a closer alignment between required and actual measurement performance, it is recommended to add an online indicator of phasor accuracy to the phasor data. <p><p>Fast automated corrective actions and closed-loop control schemes relying on synchrophasors are increasingly deployed in power systems. The delay introduced in the measurement and the telecommunication can have a negative impact on the efficiency of these schemes. Therefore, measurement latency is also a major performance indicator of the synchrophasor measurement. <p><p>This thesis illustrates the full measurement chain, from the measurement of analog voltages and currents in the power system to the use of these measurements for various purposes, with an emphasis on real-time applications: visualization, triggering of alarms in the control room or remedial actions, and integration in closed-loop controls. It highlights the various elements along this chain, which influence the availability, accuracy and delay of the data. <p><p>The main focus is on the algorithm to estimate synchrophasors and on the tradeoff between accuracy and latency that arises in applications for which measurements are taken during dynamic events and the data must be processed within a very limited timeframe. <p><p>If both fast phasors and slower, more accurate phasors are made available, the user would be able to select the set of phasors that are the most suitable for each application, by giving priority to either accuracy or a short delay.<p><p>This thesis also tentatively identifies gaps between requirements and typical measurements in order to identify current barriers and challenges to the use of wide area measurement systems. <p><p>A specific application, the continuous monitoring of oscillatory stability, was selected in order to illustrate the benefits of synchrophasors for the monitoring, analysis and control of power system behavior. This application requires a good phasor accuracy but can allow for some measurement delay, unless phasor data are used in an oscillation damping controller. In addition, it also relies on modal estimators, i.e. techniques for the online identification of the characteristics of oscillatory modes from measurements. This field of ongoing research is also introduced in this thesis. / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished

The goal of the thesis was applying multiparametric diagnostics to determine the state and wear of a high-speed milling machine. In the theoretical section, selected areas of multiparametric diagnostics have been described as well as a significant focus on vibrodiagnostics. The chosen methods for the practical section were incorporated into the group “metrological diagnostics”. Several different types of measurements have been performed on the designed test piece. The measurements were analyzed and lead to these specific results: a drawing of the test piece, a structured methodology for evaluating the test piece, recommendations for diagnostics of the specific machine, and proposals for the future development of the field of metrological diagnostics.

Disertační práce se zabývá bezkontaktní analýzou vibrací pomocí metod akustické holografie v blízkém poli. Akustická holografie v blízkém poli je experimentální metoda, která rekonstruuje akustické pole v těsné blízkosti povrchu vibrujícího předmětu na základě měření akustického tlaku nebo akustické rychlosti v určité vzdálenosti od zkoumaného předmětu. Konkrétní realizace této metody závisí na použitém výpočetním algoritmu. Vlastní práce je zaměřena zejména na rozbor algoritmů, které využívají k rekonstrukci zvukového pole v blízkosti vibrujícího objektu transformaci do domény vlnových čísel (prostorová transformace), kde probíhá vlastní výpočet. V úvodu práce je vysvětlena základní teorie metody akustické holografie v blízkém poli s popisem základních vlastností a dále rozborem konkrétních nejčastěji používaných algoritmům pro lokalizaci a charakterizaci zdroje zvuku a pro následnou vibrační analýzu. Stěžejní část práce se věnuje pokročilým metodám zpracování, které se snaží určitým způsobem optimalizovat přesnost predice zvukového pole v blízkosti vibrujícího předmětu v reálných podmínkách. Jde zejména o problematiku použitého měřicího systému s akustickými snímači, které nejsou ideální, a dále o možnost měření v prostorách s difúzním charakterem zvukového pole. Pro tento případ byla na základě literárního průzkumu optimalizována a ověřena metoda využívající dvouvrstvé mikrofonní pole, které umožňuje oddělení zvukových polí přicházejících z různých stran a tedy úspěšné měření v uzavřených prostorách např. kabin automobilů a letadel. Součástí práce byla také optimalizace, rozšíření a následné ověření algoritmů publikovaných v posledních letech pro měření v reálných podmínkách za použití běžně dostupných akustických snímačů.
