Abstract

The high reactive power demand on the electrical power grid reduces the power factor and increases voltage drop. One of the compensation methods of required reactive power is the application of capacitor banks. Among the major problems with this equipment is shock, created at the moment of connection to the grid, which can cause accidents in power stations. While studying the statistical analysis of the incidents due to use of capacitor banks, this paper analyzes the shock caused by their connection, and realistically simulates a sample power station in the EMTP / WORKS software. Finally, this paper suggests useful and efficient methods to reduce the transient conditions caused by transient capacitor banks switching to the grid. doi: 10.14456/WJST.2015.27
