O auxílio a populações carentes de alguns benefícios modernos, alcançados pela humanidade, é uma prática de promoção da cidadania. Neste trabalho é abordado um estudo técnico sobre a execução de instalações elétricas temporárias em locais isolados que visa subsidiar a atividade desenvolvida por um grupo de médicos cirurgiões que levam atendimento às populações indígenas amazônicas. O grupo Expedicionários da Saúde realiza desde 2004 expedições às comunidades amazônicas que buscam levar atendimento cirúrgico especializado às populações indígenas locais permitindo seu retorno à vida social, com a recuperação da visão e de outras habilidades essenciais para suas atividades. Um diagnóstico das condições encontradas durante uma dessas expedições mostrou que muitas das falhas que normalmente atrapalham o bom andamento das atividades executadas podem ser corrigidas com ações simples e ao alcance da equipe. As estratégias apresentadas em detalhes, como a implantação de ações de Eficiência Energética que reduzem a demanda energética, reduzem a grande necessidade de combustível e as dificuldades logísticas envolvidas no transporte dos energéticos, os cuidados na execução das instalações elétricas e dimensionamento dos grupos geradores, propiciam o aumento da disponibilidade do sistema elétrico, sua segurança e dos seus usuários e colaboram com o sucesso da expedição médica realizada. / The help to populations that need for some modern benefits, achievements of mankind, is a practice of promoting citizenship. This paper shows a technical study on the implementation of temporary electrical installations in isolated locations that is intended to subsidize the activity developed by a group of surgeons that take care of indigenous peoples of Amazonia. The group \"Expedicionários da Saúde\" held since 2004 expeditions to the Amazon communities seeking to bring specialized surgical care to indigenous populations by allowing their return to social life, with recovery of vision and other skills essential for their activities. A diagnosis of conditions found during one of these expeditions showed that many of the failures that often hinder the normal progress of activities can be corrected with simple actions that can be done by the team itself. The strategies presented in detail, as the implementation of energy efficiency actions that reduce energy demand, reduce the large need for fuel and the logistical difficulties involved in its transporting, the cares in carrying out electrical installations and optimal sizing of generators, provide increasing the availability of the electrical system, its security and its users and collaborate with the success of the expedition doctor performed.

Under deregulated environments, transmission system is playing an increasingly vital role in the modern power markets. Despite the widespread experience of electricity restructuring during the past decade, important issues remain open about the best way to organize transmission to support reliability management and market trading. In the absence of an appropriate mechanism for the transmission services unbundling, it is unlikely to take into consideration the effects of power flows that diverge from the contract path. When individuals do not confront the respective responsibility for the transmission services, the market outcome will be inefficient. Allocations of transmission loss and costs to the market participants are essential for the transmission services unbundling. In this respect, two methods are proposed in this dissertation to provide technical and economical signals for the allocations. Based on circuit theory, the first method proposes a new procedure to trace the power flows on the transmission lines. Starting with the computation of an individual generator¡¦s or load¡¦s contributions to the line currents, the network is then decomposed into different networks. In each decomposed network, bus injections and line power flows are replaced by components related to only one generator or load. Based on the components of real power flow on the transmission lines, the allocations of transmission loss and supplementary cost can be easily performed. In the second method, AC power flow based injection shift distribution factors (ISDFs) are exploited for calculating generalized generation distribution factors (GGDFs) and generalized load distribution factors (GLDFs). GGDFs and GLDFs can be used to derive the components of the real powers on each transmission line contributed by the generators and loads. Three bus-oriented schemes are proposed to allocate the transmission loss. They are aimed to reduce the number of distribution factor computation and to reflect the activity in a competitive market. The reactive powers incurred on transmission lines due to the generators and loads are also derived using the reactive power distribution factors (RPDFs). Based on the components of complex power flow on the transmission lines, transmission cost allocation methods are proposed to charge the impacts of power transactions on the network. In order to take the service reliability into account the service charges consist of the components representing normal and the contingency states respectively.
