<p>During the last decade, power quality has been recognised asa global problem. Among different types of power qualityproblems, voltage sags have been identified to be one of themost severe problems for different process industries. The mostcommon reason to voltage sags is lightning strikes in powerlines. Protection equipment, usually located at switchyards,disconnect faulted power lines as soon as possible, which isapproximately 100 ms. Thus, the duration of voltage sags areapproximately 100 ms. The sensitivity to voltage sags ofelectrical equipment in process industries can be observed asfor instance malfunction, automatic turnoff or damages.</p><p>This thesis gives an overview of three metals processes withfocus on the sensitivity to voltage sags and interruptions. Theinherent energy in the process is used to find the sensitivity.This energy may also be used to obtain "ride-through" for theprocesses. The three metals processes are a blast furnaceprocess, a hot rolling mill process and a cold rolling millprocess. The main attention in this thesis is paid to the blastfurnace process, which is powered by a line-operatedsynchronous machine.</p><p>The thesis shows that the protection equipment forelectrical machines can be adjusted to avoid unnecessaryshutdowns. It is also explained why there are high torque andcurrents during voltage sags as well as after voltage sags. Itis shown that the first peak torque and current during thevoltage sags is almost proportional to the voltage change, thatis the voltage magnitude before the voltage sag minus thevoltage magnitude during the voltage sag. The first peak torqueand current after the voltage sag depends sinusoidal-like onthe duration of the voltage sag and almost proportional to thevoltage change during the voltage sag. There is no fluxsaturation during voltage sags, however after voltage sagssaturation is very likely to occur. The thesis explains why andalso how the flux is changed during and after voltage sags.</p><p>The duration of voltage sags is in many cases set by theprotection equipment located in switchyards. It is shown thatthe durations of voltage sags can be changed to durations thatwill cause less peak torque and current after voltage sags forline-operated AC-machines. It is also shown how this istheoretically achieved.</p><p><b>Keywords:</b>Rolling mill, Blast furnace, Power Quality,Synchronous machine, Asynchronous machine, Voltage sag, Voltageinterruption, Ride-through, Process disturbances, Simulation,Modelling</p>

Alkalic porphyry style Au-Cu deposits of the Cadia district are associated with Late-Ordovician monzonite intrusions, which were emplaced during the final phase of Macquarie Arc magmatism at the end of the Benambran Orogeny. N-striking faults, including the curviplanar, northerly striking, moderately west-dipping basement thrust faults of the Cadiangullong system, developed early in the district history. NE-striking faults formed during rifting in the late Silurian. Subsequent E-W directed Siluro- Devonian extension followed by regional E-W shortening during the Devonian Tabberabberan Orogeny dismembered these intrusions, thereby superposing different levels porphyry Au-Cu systems as well as the host stratigraphy. During the late Silurian, the partially exhumed porphyry systems were buried beneath the Waugoola Group sedimentary cover sequence, which is generally preserved in the footwall of the Cadiangullong thrust fault system. The Waugoola Group is a typical rift-sag sequence, deposited initially in local fault-bounded basins which then transitioned to a gradually shallowing marine environment as local topography was overwhelmed. Basin geometry was controlled by pre-existing basement structures, which were subsequently inverted during the Devonian Tabberabberan Orogeny, offsetting the unconformity by up to 300m vertically. In the Waugoola Group cover, this shortening was accommodated via a complex network of minor detachments that strike parallel to major underlying basement faults. For this reason, faults and folds measured at the surface in the sedimentary cover can be used as a predictive tool to infer basement structures at depth.

Thesis (MScEng)--University of Stellenbosch, 2001. / ENGLISH ABSTRACT: This thesis covers the development of a multilevel cascaded inverter for the purpose of costeffective transformerless series dip compensation. Of all known power quality problems, voltage dips are the greatest reason for concern. Dips/sags occur more frequently than outages and therefore tend to be more costly for industry as modem technical equipment becomes all the more sensitive to the quality and reliability of supply. A number of devices already exist to compensate for this problem, but the cost of most of these systems does not always justify the financial losses they compensate for. All of these systems are using transformers and/or large filter components that contribute to the size, price and losses to quite a large extent. Series injection dip compensators offer the advantage of only having to compensate for the decrease in supply voltage during a dip. This results in a significant reduction in the converter ratings and energy storage requirements compared to conventional uninterruptible power supplies or shunt injection power quality devices. Existing inverter topologies, including multilevel inverters, were therefore studied and compared as possible solutions for cost-effective transformerless series dip compensation. On the basis of these considerations the multilevel cascaded inverter seems to be the most cost-effective option. The relatively low harmonic content of its unfiltered output also eliminates the need for a large output filter. A single-phase dip compensator, with this topology, was designed and built according to specifications stated by Eskom, the main utility in South Africa. Batteries as energy storage and automotive MOSFETs as switching components, proved to be most cost-effective options for the specified power ratings. Control algorithms for dip compensation with the multilevel inverter were also developed. Some of these algorithms are based on existing techniques, but two new algorithms were also developed to implement force commutation of the thyristors and to share the power dissipation in the dip compensator. Simulations indicated that these algorithms could be suitable and sufficient for their application. This dip compensator with its control algorithms was tested with a dip generator, developed at the University of Stellenbosch, for different types of loads. The experimental results confirmed the simulations and showed a very good performance for the specified conditions. An optimised design of this dip compensator will make it a cost-effective solution for dip compensation. / AFRIKAANSE OPSOMMING: Hierdie tesis dek die ontwikkeling van 'n multivlakwisselrigter, in kaskade, met koste-effektiewe transformatorlose duik kompensasie as mikpunt. Van al die bekende toevoerkwaliteit probleme wek duike in die spanning die meeste kommer. Duike kom meer gereeld voor as kragonderbrekings en neig daarom om 'n groter onkoste te wees vir die industrie soos wat moderne tegnologiese toerusting al hoe meer sensitief raak vir die kwaliteit en betroubaarheid van die toevoer. 'n Aantal toestelle wat vir hierdie probleem kompenseer bestaan reeds, maar die koste van hierdie stelsels regverdig nie altyd die finansiële verliese wat hulle moet elimineer nie. Al hierdie stelsels gebruik transformators en/of groot filter komponente wat grootliks bydra tot die grootte, prys en verliese van hierdie stelsels. Serie-injeksie kompenseerders het die voordeel dat hulle net kompenseer vir die verlies in die toevoerspanning tydens die duik. Dit het 'n beduidende vermindering in die omsetterkenwaardes en energiestoorvereistes tot gevolg in vergelyking met ononderbroke kragbronne (UPS) of newe-injeksie toevoerkwaliteit toestelle. Daarom IS bestaande wisselrigtertopologië, insluitende multivlakwisselrigters, bestudeer en vergelyk as moontlike oplossings vir koste-effektiewe serie duik-kompensasie. Van al hierdie moontlikhede lyk die multivlakwisselrigter, in kaskade, na die mees koste-effektiewe opsie. Die relatiewe lae harmoniese inhoud van sy ongefilterde uittree elimineer die behoefte aan 'n groot uittreefilter. 'n Enkelfase duik kompenseerder, met hierdie topologie, is ontwerp en gebou volgens die spesifikasies wat vasgestel is deur Eskom, die hoof elektriese kragvoorsiener in Suid-Afrika. Dit het geblyk dat batterye, en MOSFETte uit die motorbedryf, die mees koste-effektiewe opsies bied vir onderskeidelik die energiestoor en skakelkomponente. Beheeralgoritmes VIr duik kompensasie met die multivlakwisselrigter is ook ontwikkel. Sommige van hierdie algoritmes is gebaseer op bestaande tegnieke, maar twee nuwe algoritmes is ook ontwikkel vir die kommutering van die tiristors en die deling van die drywingsverkwisting in die duik kompenseerder. Simulasies dui aan dat hierdie algoritmes geskik en voldoende kan wees vir hulle toepassing. Hierdie duik kompenseerder met sy beheeralgoritmes is getoets vir verskillende tipes laste met 'n duikgenerator wat ontwikkel is by die Universiteit van Stellenbosch. Die eksperimentele resultate bevestig dit wat verkry is uit die simulasies en wys 'n goeie werkverrigting vir die gespesifiseerde kondisies. 'n Geoptimeerde ontwerp van hierdie duik kompenseerder sal dit 'n koste-effektiewe oplossing maak vir duik kompensasie.

This study aims to provide subsidies for groundwater management at the basin of Rio Santa Maria-BHRSM. Located in the southwest of Rio Grande do Sul state, Brazil, on the edge of Paraná Basin and transitioning towards the Uruguaio Sul-Riograndense Shield, has an area of 15,797,300 square kilometers. About 16 formations occur in outcrops Pavão (2004), of which 36% arises as the Guarani Aquifer System/GAS. The outcrop areas represent areas of direct recharge of GAS and of locally discharge on BHRSM. Four Hydrogeologic Domains have gathered CPRM (2007). Domains 1 and 2 form intergranular porous aquifers in 83.08%. Domains 5 and 6 form fissural aquifers in 16.92%. An outline for the use of draft coverage criteria was elaborated, for granting the use of groundwater: Global, Regional and Local. On the Global scale, were approached four Hydrogeologic Domains, three Hydrogeologic Provinces, seven Hydrogeologic Sub-Provinces; seven Hydrogeologic Systems (six aquifers and one aquitard) and sixteen Hydrostratigraphic Units. The Regional scale approaches the Catchment and its 21 Reference Hydrological Sections, designed for sectorizing the surface water studies and sometimes used for the management of groundwater. A database on 590 hydrogeological captures was developed. The potentiometric quotas indicating groundwater flow, vadose zone, concentrations of Total Dissolved Solids-TDS, nitrates concentrations and vulnerable to contamination of aquifers Method GOD Foster et al. (2006) were spacialized as thematic maps. The gathered information gave rise to the SIG-BHRSM shapefiles containing the plans relating to information for each theme. The preponderant use of groundwater supplies is human, by forming a greater amount of information in urban areas and gaps in rural areas. The predominant groundwater flow is south-to-north, along the trim of the natural terrain. As to the potentiometry, were acknowledged evidences of contribution of groundwater to the Rivers base flow, establishing a cross-border Brazil-Uruguay flow and vice versa. The prevalent vulnerability classes were: high 35.6%, moderate 30.2%, low 26.5%, negligible 5.7% and extreme 0.4%. The areas with information gaps accounted 1.1% of BHRSM. The overlap of the TDS test concentrations in classes 1 and 2 to the vulnerability to contamination of groundwater will apply as guideline for the implementation of management tools, integrated with other policies to protect the physical environment. These guidelines have been spatialized into three scales: the Global scale accounting 1: 250,000 or less (in general), the Regional scale rating between. 1: 250,000 and 1: 50,000 (semi-detailed), and the Local rating 1: 50,000 or higher (greater detail). This segmentation in scales intends to subsidize the implementation of integrated management tools for groundwater resources in a basin. / O presente estudo visa fornecer subsídios para gestão das águas subterrâneas na Bacia Hidrográfica do Rio Santa Maria-BHRSM. Localizada no sudoeste do Estado do Rio Grande do Sul na borda da Bacia do Paraná na transição para o Escudo Uruguaio Sul-Riograndense, possui uma área de 15.797,300 km². Ocorrem aflorantes cerca de 16 formações geológicas Pavão (2004) destas o Sistema Aquífero Guarani ocorre em cerca de 36%. Estas áreas aflorantes representam áreas de recarga direta dos aqüíferos e localmente de descarga na BHRSM. Reuniram-se em quatro Domínios Hidrogeológicos CPRM (2007). Os Domínios 1 e 2 formam Aqüíferos porosos intergranulares 83,08%. Os Domínios 5 e 6 formam Aquíferos fissurais 16,92%. Elaborou-se uma proposta de utilização de escalas de abrangência para critério de outorga de uso das águas subterrâneas: Global, Regional e Local. Na escala Global consideraram-se 4 Domínios Hidrogeológicos; 3 Províncias e 7 Sub-Províncias; 7 Sistemas Hidrogeológicos (6 aquíferos e 1 aquitardo) e 16 Unidades Hidroestratigráficas. A escala Regional considerou a Bacia Hidrográfica e suas 21 Seções Hidrológicas de Referência-SHR criadas para setorizar as águas superficiais. Elaborou-se um banco de dados hidrogeológicos relativos a 590 captações por poços. Espacializaram-se na forma de mapas temáticos, as cotas potenciométricas indicativas dos fluxos subterrâneos, a zona vadosa, as concentrações de Sólidos Totais Dissolvidos-STD, as concentrações dos nitratos e a vulnerablidade à contaminação dos aquíferos Método GOD Foster et al. (2006). Essas informações deram origem ao SIG-BHRSM contendo os shapefiles referentes aos planos de informações. O uso preponderante das águas subterrâneas é o abastecimento humano, dispondo-se de uma maior quantidade de informações em áreas urbanas e vazios em áreas rurais. O fluxo subterrâneo predominante tem direção sul-norte, acompanhando o caimento natural do terreno. A potenciometria notou-se evidências da uma contribuição dos aquíferos para os escoamentos de base dos cursos de água, além de se constatar a existência de um fluxo transfronteiriço para o lado Uruguaio. As classes de vulnerabilidade foram: alta 35,6%, seguida da média 30,2%, baixa 26,5%, insignificante 5,7 % e na extrema 0,4%. As áreas com vazios de informação corresponderam a 1,1% da BHRSM. A sobreposição do critério concentrações de STD nas classes 1 e 2 ao da vulnerabilidade à contaminação das águas subterrâneas servirão de diretrizes para a implementação dos instrumentos de gestão de forma integrada com as demais políticas de proteção ao ambiente físico. Estas diretrizes foram espacializadas em três escalas: a Global igual ou menor a 1: 250.000 (generalizada), a Regional entre. 1: 250.000 e 1: 50.000 (semi-detalhe) e a Local, de 1: 50.000 ou maior (maior detalhe). Esta segmentação em escalas visa subsidiar a implementação dos instrumentos de gestão dos recursos hídricos subterrâneos em uma bacia hidrográfica.

abstract: This thesis presents research on innovative AC transmission design concepts and focused mathematics for electric power transmission design. The focus relates to compact designs, high temperature low sag conductors, and high phase order design. The motivation of the research is to increase transmission capacity with limited right of way. Regarding compact phase spacing, insight into the possibility of increasing the security rating of transmission lines is the primary focus through increased mutual coupling and decreased positive sequence reactance. Compact design can reduce the required corridor width to as little as 31% of traditional designs, especially with the use of inter-phase spacers. Typically transmission lines are built with conservative clearances, with difficulty obtaining right of way, more compact phase spacing may be needed. With design consideration significant compaction can produce an increase by 5-25% in the transmission line security (steady state stability) rating. In addition, other advantages and disadvantages of compact phase design are analyzed. Also, the next two topics: high temperature low sag conductors and high phase order designs include the use of compact designs. High temperature low sag (HTLS) conductors are used to increase the thermal capacity of a transmission line up to two times the capacity compared to traditional conductors. HTLS conductors can operate continuously at 150-210oC and in emergency at 180-250oC (depending on the HTLS conductor). ACSR conductors operate continuously at 50-110oC and in emergency conditions at 110-150oC depending on the utility, line, and location. HTLS conductors have decreased sag characteristics of up to 33% compared to traditional ACSR conductors at 100oC and up to 22% at 180oC. In addition to what HTLS has to offer in terms of the thermal rating improvement, the possibility of using HTLS conductors to indirectly reduce tower height and compact the phases to increase the security limit is investigated. In addition, utilizing HTLS conductors to increase span length and decrease the number of transmission towers is investigated. The phase compaction or increased span length is accomplished by utilization of the improved physical sag characteristics of HTLS conductors. High phase order (HPO) focuses on the ability to increase the power capacity for a given right of way. For example, a six phase line would have a thermal rating of approximately 173%, a security rating of approximately 289%, and the SIL would be approximately 300% of a double circuit three phase line with equal right of way and equal voltage line to line. In addition, this research focuses on algorithm and model development of HPO systems. A study of the impedance of HPO lines is presented. The line impedance matrices for some high phase order configurations are circulant Toeplitz matrices. Properties of circulant matrices are developed for the generalized sequence impedances of HPO lines. A method to calculate the sequence impedances utilizing unique distance parameter algorithms is presented. A novel method to design the sequence impedances to specifications is presented. Utilizing impedance matrices in circulant form, a generalized form of the sequence components transformation matrix is presented. A generalized voltage unbalance factor in discussed for HPO transmission lines. Algorithms to calculate the number of fault types and number of significant fault types for an n-phase system are presented. A discussion is presented on transposition of HPO transmission lines and a generalized fault analysis of a high phase order circuit is presented along with an HPO analysis program. The work presented has the objective of increasing the use of rights of way for bulk power transmission through the use of innovative transmission technologies. The purpose of this dissertation is to lay down some of the building blocks and to help make the three technologies discussed practical applications in the future. / Dissertation/Thesis / Doctoral Dissertation Electrical Engineering 2015

The scramble competition is considered an indirect type of competition, mainly associated with factors like group size and distribution of resources. Contest competition occurs when individuals compete directly for resources. In species that exibit this type of competition the establishment of dominance hierarchy can occur, resulting in differences on feeding and reproductive benefits for each member of the group. In these cases, aggressive and submissive behaviors are expected as a way to signal social status. The aim of this study was to investigate the effects of social hierarchy over food ingestion in Callithrix jacchus. Data recording was from September/2006 to March/2007, eight days by month, at Floresta Nacional de A?u do Instituto Chico Mendes de Biodiversidade. The observation time started at 05:00 AM and finished after the last animal was on the sleeptree. Analyses of aggressive interactions, behavioral profile and diet, reveals a lot of advantages for dominat animals in the study group. Dominant individuals had higher intake of animal matter that subordinates. The last ones, consumed fruits, exsudate and, eventually, explored itens that were not common to the diet. We suggest that dominance hiearchy enable the reproductive female to assure priority on access to food resources, a important caracteristc to supply tha costs to maintain tha high reproductive taxa of the specie. We also suggest that reproductive male, due to the participation on food transfer, had the forage efficience reduced / A vida em grupo implica em competi??o por recursos entre os indiv?duos. Competi??o do tipo Scramble ? considerada um modo indireto de competi??o, associado principalmente a fatores como tamanho do grupo e distribui??o dos recursos no ambiente. Competi??o do tipo Contest ocorre quando indiv?duos competem diretamente por recursos. Em esp?cies sujeitas a esse modo de competi??o pode ocorrer estabelecimento de hierarquia de domin?ncia, resultando em diferen?as nos benef?cios obtidos pelos indiv?duos no ?mbito alimentar e reprodutivo. Intera??es agressivas, bem como exibi??es de submiss?o, s?o esperadas como forma de sinalizar status social. Neste estudo investigamos o modo como a hierarquia social atua sobre o sucesso alimentar em Callithrix jacchus. De setembro de 2006 a mar?o de 2007 observamos um grupo selvagem de sag?is na Floresta Nacional de A?u do Instituto Chico Mendes de Biodiversidade, 8 dias por m?s. As observa??es tinham inicio ?s 05:00 e t?rmino ap?s todos os indiv?duos se recolherem ? ?rvore de dormir. A coleta de dados foi realizada atrav?s da t?cnica animal focal com registro instant?neo a cada minuto, durante 15 minutos consecutivos. Analisando as intera??es agon?sticas, perfil comportamental e perfil alimentar do grupo, verificamos que a hierarquia social em C. jacchus, al?m dos benef?cios reprodutivos, tamb?m confere uma s?rie de vantagens no ?mbito alimentar ao casal reprodutor. Em nosso estudo, intera??es agressivas, incluindo persegui??es, arranh?es e mordidas, foram pouco freq?entes de modo intragrupo. As rela??es de domin?ncia, portanto, foram mais evidentes atrav?s de comportamentos de submiss?o. N?o constatamos diferen?as significativas entre os animais em rela??o ? taxa de ingest?o total. Todavia, a an?lise do perfil alimentar (propor??o de mat?ria animal e vegetal na dieta) revelou que dominantes asseguraram maior ingest?o de mat?ria animal, enquanto subordinados utilizaram frutos, exsudado e, eventualmente, exploraram itens que n?o eram comuns ? dieta. Sugerimos que atrav?s da hierarquia social, a f?mea reprodutora assegura acesso preferencial a recursos alimentares, sendo esta uma importante caracter?stica para suprir os custos envolvidos com a manuten??o da alta taxa reprodutiva verificada para a esp?cie.

abstract: The worldwide demand for electric energy is slated to increase by 80% between the years 1990 and 2040. In order to satisfy this increase in load, many new generators and transmission lines are planned. Implementations of various plans that can augment existing infrastructure have been hindered due to environmental constraints, public opposition and difficulties in obtaining right-of-way. As a result, stress on the present electrical infrastructure has increased, resulting in congestion within the system. The aim of this research is to analyze three techniques that could improve the power transfer capability of the present electric grid. These include line compaction, use of high temperature low sag conductors and high phase order systems. The above methods were selected as they could be readily employed without the need for additional right-of-way. Results from the line compaction tests indicate that line compaction up to 30% is possible and this increases the power transfer capability up to 53%. Additional advantages of employing line compaction are the reduction in electric and magnetic fields, increase in system stability and better voltage regulation. High temperature low sag conductors that were applied on thermally limited lines were seen to increase the power transfer capability. However, a disadvantage of this technique was that the second most congested line, limits the power transfer capability of the system. High phase (six phase) order system was noted to have several advantages over three phase system such as lower voltage requirement to transfer equal amount of power and lower electric and magnetic field across the right of way. An IEEE 9 and 118 bus test system were used to evaluate the above mentioned techniques. / Dissertation/Thesis / M.S. Electrical Engineering 2012

Alkalic porphyry style Au-Cu deposits of the Cadia district are associated with Late-Ordovician monzonite intrusions, which were emplaced during the final phase of Macquarie Arc magmatism at the end of the Benambran Orogeny. N-striking faults, including the curviplanar, northerly striking, moderately west-dipping basement thrust faults of the Cadiangullong system, developed early in the district history. NE-striking faults formed during rifting in the late Silurian. Subsequent E-W directed Siluro- Devonian extension followed by regional E-W shortening during the Devonian Tabberabberan Orogeny dismembered these intrusions, thereby superposing different levels porphyry Au-Cu systems as well as the host stratigraphy. During the late Silurian, the partially exhumed porphyry systems were buried beneath the Waugoola Group sedimentary cover sequence, which is generally preserved in the footwall of the Cadiangullong thrust fault system. The Waugoola Group is a typical rift-sag sequence, deposited initially in local fault-bounded basins which then transitioned to a gradually shallowing marine environment as local topography was overwhelmed. Basin geometry was controlled by pre-existing basement structures, which were subsequently inverted during the Devonian Tabberabberan Orogeny, offsetting the unconformity by up to 300m vertically. In the Waugoola Group cover, this shortening was accommodated via a complex network of minor detachments that strike parallel to major underlying basement faults. For this reason, faults and folds measured at the surface in the sedimentary cover can be used as a predictive tool to infer basement structures at depth. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
