Risk management for a rural electrification project : a systems engineering approach

Zondi, Lucky 04 June 2012 (has links)
M.Ing. / This research study is about evaluating the practicability of using systems engineering approach to rural electrification project risk management. The research was motivated by rural electrification projects in South Africa that have suffered planning, design or operational problems due to uncertainties at project site level. The dissertation begins by describing the rural electrification background in the first chapter. The process of electrifying rural areas, challenges, and achievements so far in South Africa are presented. The government target for universal access to electricity is also highlighted. The next two chapters address the theory of systems engineering, and project risk management as one of the elements of project management. The theory of systems engineering approach to risk management is then applied to a typical electrification project structure. The electrification project is viewed as a system, with risk management as a sub-system of project management. A case study is presented for a rural electrification project in KwaZulu-Natal that has experienced design and operational problems. A risk system is identified from work breakdown structure, and risk hierarchy framework is produced based on project life cycle cost model. Risks are ranked in terms of their impact and probability. The aim of the study is to understand the impact of each risk on general project risk, and risk mitigation measures that should be taken to address those risks. The research finishes by drawing a conclusion that electrification projects are complex, risks are manageable, and systems thinking can be successfully used to manage electrification project risks. Risk management must focus on the project as a whole, including operation and maintenance, rather than focusing at individual project stages.

Com novas e modernas tecnologias à disposição, o produtor rural tem a propriedade valorizada e pode buscar alternativas agrícolas para aumentar sua renda liquida e gerar empregos, além de estimular o mercado de produtos industrializados. O objetivo deste trabalho é avaliar a evolução do Programa de Eletrificação Rural “Luz para Todos”, e apresentar os principais aspectos técnicos e sociais do programa, como veículo no desenvolvimento, referente aos pequenos produtores rurais na área de atuação da cooperativa de Eletrificação Rural de Itaí, Paranapanema e Avaré (CERIPA). Para tanto, foram analisados dados técnicos, financeiros e sociais, através de cadastros e planilhas, com o devido acompanhamento da implantação do Programa. Através destes dados, foi possível determinar índices técnicos e econômicos referentes à implantação do Programa e verificar a evolução do número de consumidores, a potência instalada, a energia faturada e receita bruta da cooperativa. Para a cooperativa, a implantação do programa promoveu um vetor de desenvolvimento, pois todos os consumidores atendidos, englobaram na massa de consumidores da cooperativa, tornando-a mais sólida e mais competitiva no mercado energético. Em apenas sete anos, no período de 2000 a 2006, a cooperativa teve um aumento de mais de 50% no número de ligações, dado este que se refletiu na carga instalada, triplicando o faturamento bruto. Pode-se notar no desenvolvimento deste trabalho uma forte omissão do governo com relação às metas estabelecidas e não cumpridas, onde se aplica simplesmente uma multa simbólica sobre o investimento não utilizado no programa.

With new and modern technologies available, the rural producer has his property valorized and is able to search for agricultural alternatives to rise his net income and generate employment, besides stimulating the industrialized products market. This work aims to evaluate the evolution of the “Electric Lighting for All” Program and present main technical and social aspects of the program, as a vehicle of development, referring to the rural small farmers at CERIPA Rural Electrification Cooperative of Itaí, Paranapanema and Avaré. It was analyzed technical, financial and social data through registers and sheets with the proper following of the Program implantation. From the data, it was possible to determine the technical and economic indexes related to the Program settlement and verify the increase in number of consumers, installed power, the invoiced electrical energy and gross income of the Cooperative. For the Cooperative, this Program settlement promoted a vector of development, since all the attended small farmers entered the cooperative, making it more solid and competitive in the market. From 2000 to 2006, the cooperative enhanced over 50% reflecting in the installed power, triplicating the gross income.It can be noticed in this work development high omission of the government concerning the established targets not accomplished, where a symbolic tip is simply applied over the investment not used in the program. Problems are not raised, targets are not questioned; the allowance is distributed only to justify a “political willing” with the citizen.

Organically Grown Microgrids: the Development and Simulation of a Solar Home System-based Microgrid

Unger, Kurtis January 2012 (has links)
The United Nations has declared 2012 the ``International Year of Sustainable Energy for All''. A substantial portion of the world's population (some 1.3 billion people) currently live without electricity and development efforts to reach them are progressing relatively slowly. This thesis follows the development of a technology which can enable community owned and operated microgrids to emerge based solely on the local supply and demand of that community. Although this thesis ends with the technical analysis of a DC/DC converter, there is a significant amount of background to cover in order to properly understand the context in which it will be used. After providing an introduction into typical rural electrification efforts and pointing out some of the shortcomings of these projects, this thesis introduces some cutting edge efforts which combine solar home system technology with cellular technology and discusses the benefits of such a marriage of technology. Next, the research proposes some tweaks to this novel technology and provides a high-level economic demonstration of the spread of solar home systems in a community based on these modifications. It then takes this concept even further and proposes the addition of a DC/DC converter which could turn these individual solar home systems into a proper microgrid. This thesis elaborates on the development process of simulating such a microgrid in PSCAD, including the individual components of a solar home system and the specific task of designing the converter which would form the backbone of the proposed microgrid. The final simulations and analyses demonstrate a microgrid that is both technically and economically feasible for developing world applications.

[en] METHODOLOGIC FOR ASSESSMENT OF RURAL ELECTRIFICATION PROGRAM THROUGH MULTIVARIATE ANALYSIS / [pt] METODOLOGIA PARA AVALIAÇÃO DO PROGRAMA DE ELETRIFICAÇÃO RURAL VIA ANÁLISE MULTIVARIADA

CRISTIANE FARIAS CAMACHO 10 July 2003 (has links)
[pt] A realidade vivida pela população rural tem sempre surpresas a revelar e mais ainda quando se trata do meio rural não eletrificado. Este estudo examina uma parte da realidade do cotidiano vivido por propriedades rurais envolvidas no Programa de Eletrificação Rural Luz no Campo, mostrando o modo de vida das propriedades na fase anterior ao recebimento de energia elétrica. Através do data mining dos dados coletados na pesquisa de campo do estado do Mato Grosso do Sul e da aplicação de técnicas de análise multivariada, tais como: Análise de Fatores e Análise de Cluster, este estudo possibilitará a visualização do modo de vida de propriedades não eletrificadas permitindo posteriormente a comparação com a chegada da energia elétrica que propiciará a avaliação do Programa de Eletrificação Rural. O modelo foi aplicado em dados de duas concessionárias de energia elétrica do Brasil usando dados horários coletados durante dois anos. / [en] The reality lived by the rural population has always some surprises to reveal, even more when it's about the not electrified rural domain. This research examines a part of the reality lived by homestead involved in the Rural Electrification Program Luz no Campo, showing their way of life in the previous phase of the electricity receipt. Through the data mining of the collected data in the field research in Mato Grosso do Sul state and with the application a varied of statistical multivariate techniques such as: Factors Analysis and Cluster Analysis, this research will provide the visualization of the way of life of non electrified properties allowing a later comparison with the data collected in the same properties, after the arrival of the electricity. This way, it will be possible to establish a formal evaluation of the Rural Electrification Program.
