A New Method for Determination of Minimum Break Points Using Genetic Algorithm

Nowadays in order to increase the reliability and other special aims, the power networks are exchanged to the large and interconnected networks. In such networks, the relays setting and coordination is complicated and needs to determine break points. Break points are the initial points in coordination process and in pervious works, different methods are proposed to finding them in interconnected networks. In this paper, a method proposed to determine suitable break point set, considering some parameters such as pilot protection, Short circuit level, … This method determines minimum break point set using genetic algorithm. After obtaining the solutions, the coordination is fulfilled using the obtained break point set and the break points are modified considering the coordination criteria.
