| Abstract | |
The electric power distribution systems are experiencing significant changes due to the integration of new technologies, such as photovoltaic solar generators, electric vehicles, energy storage systems, and smart meters. Due to the high complexity of this new condition, there is a critical need for more efficient practices of distribution systems management. Among the management practices that needs improvement is the fault location, which aims to accurately indicate the location of a short circuit (fault) allowing the system to be recovered as soon as possible. In this context, this research investigates the use of data potentially available with the modernization of the distribution systems in fault location process. A fault location method based on sparse voltage measurement is used considering, among other factors, an environment with high penetration of distributed generation. The integration of the distributed generators can be accompanied by a greater data availability, currently not accessible to the distribution utilities and can aid the fault location process. In addition, this work evaluates the possibility of improving the load estimation using measurements from smart meters and approaches to reduce the search zone of the fault location. An extensive evaluation was performed in two real networks and the results show mainly that the distributed generators do not affect the performance of the method and the increase of the amount of voltage measurements substantially improve the performance of the studied method (AU) | |
