Abstract. Data fusion with different types of data that used for grid fault location can bring more accurate and clear results. Therefore, a new method for fault location which contains multi grid current and voltage, time and coordinate data information is proposed. Transient traveling wave is analyzed for determine the required data information in the first place, and then affirm the positioning principle and the selection rules of positioning network according to characteristics of multi fault traveling wave. Finally, Grid fault location will be precisely positioned by applying multiple data grid fault location algorithm. Simulation results shows that the proposed method is feasible, and the new algorithm has higher positioning accuracy.

Este exemplar foi revisado e corrigido em relação à versão original, sob responsabilidade única do autor e com a anuência de seu orientador. This research presents the development and implementation of fault location algorithms in power distribution networks with distributed generation units installed along their feeders. The proposed algorithms are capable of locating the fault based on voltage and current signals recorded by intelligent electronic devices installed at the end of the feeder sections, information to compute the loads connected to these feeders and their electric characteristics, and the operating status of the network. In addition, this work presents the study of analytical models of distributed generation and load technologies that could contribute to the performance of the proposed fault location algorithms. The validation of the algorithms was based on computer simulations using network models implemented in ATP, whereas the algorithms were implemented in MATLAB.Keywords: power system protection, power system automation, fault location, distributed generation. ResumoSouto, Laiz Localização de faltas em redes elétricas de distribuição com a presença de unidades de geração distribuída. 114 p. Dissertação de mestradoEscola Politécnica, Universidade de São Paulo, 2016.Esta pesquisa apresenta o desenvolvimento e a implementação de algoritmos para localização de faltas em redes primárias de distribuição de energia elétrica que possuem unidades de geração distribuída conectadas ao longo dos seus alimentadores. Esses algoritmos são capazes de efetuar a localização de faltas utilizando registros dos sinais de tensões e correntes realizados por dispositivos eletrônicos inteligentes, instalados nas saídas dos alimentadores de distribuição, além de informações que permitam determinar os valores das cargas conectadas nesses alimentadores, características elétricas, e o estado operativo da rede de distribuição. Ademais, este trabalho apresenta o estudo de modelos analíticos de unidades de geração distribuída e de cargas que poderiam contribuir positivamente com o desempenho dos algoritmos propostos. A validação dos algoritmos foi realizada através de simulações computacionais, utilizando modelos de rede implementados em ATP e os algoritmos foram implementados em MATLAB.Palavras-chave: proteção de sistemas elétricos, automação de sistemas elétricos, localização de faltas, geração distribuída.
