Optimal placement of switching and protection equipments, and the impact of the installation of fault indicators on reliability indices

In this paper, it is presented algorithms to

determine the optimal locations of switching and protection

equipments in a distribution network in order to improve its

reliability. It also presents an algorithm to evaluate the impact of

the installation of fault indicators on the reliability indices. For

the modeling and programming of the used algorithms, the

software for simulation of electrical power systems DIgSILENT

PowerFactory was used. The article also describes the results of

applying these algorithms in seven electrical distribution systems.
