Improve the Power Quality in Electrical Railway Power System Using Fuzzy Logic Controller

Abstract

This paper is to create Power Quality in Electric Railway systems with the assistance of Fuzzy Logic controller. Concentrating on the cargo prepare prevailing electrical railroad power system (ERPS) blended with air conditioning dc and air conditioning dc-air conditioning trains (its power factorϵ[0.70,0.84]), this paper proposes a power factor situated railroad power flow controller (RPFC) for the power quality improvement of ERPS. In this paper the thorough relationship of the primary power factor, converter limit, and the two phase load currents are introduced. By this technique we can likewise control the power flow trade between the grid and the load, with the goal that instantaneous active and reactive power is maintain constant. Moreover, as the main commitment of this paper, the ideal remunerating procedure suited the irregular varied two phase loads is broke down and planned based on a genuine footing substation, for the reasons for fulfilling the power quality standard, improving RPFC's control adaptability, and diminishing converter's ability. Here we are utilizing the fuzzy controller contrasted with different controllers i.e. The fuzzy controller is the most reasonable for the human basic leadership component, giving the operation of an electronic system with choices of specialists. What's more, utilizing the fuzzy controller for a nonlinear system takes into account a decrease of indeterminate impacts in the system control and enhances the effectiveness. By utilizing simulation results we can examine the improvement of the power quality in electric railroad systems utilizing fuzzy logic controller.
