Abstract
There are many fundamental differences between electric traction networks and other industrial supply networks in terms of dynamic behavior and static characteristics. For example, the time variation of a load causes voltage variations in a supply network, which results in variations of power flow in the supply network. Today, reactive power compensators are the most practical solutions for keeping voltage levels in normal boundaries. In this paper, with the aim of fuzzy logic, a method for compensating reactive power losses in electrical traction networks is proposed. The proposed method has many advantages such as decreasing the reactive power compensation costs, determining the optimum switching step of capacitor banks and deducing the losses in electric traction networks.

Summary
Reactive power creates numerous problems in electric railway supply networks. Because of the particular characteristics of electric traction loads, the problems have higher intensity in railway supply networks than other types of electric supply networks. Reactive power can be compensated by implementation of active or static methods. Allocation of these shunt capacitors in the network shall be according to the power network topology. This paper proposed improving power quality based on optimization of capacitor allocation in electric railway power supply network.
