Hybrid Power Quality Compensator for Traction Power System with Photovoltaic Array

A hybrid power quality compensator (HPQC) is proposed for comprehensive compensation under minimum dc operation voltage in high-speed traction power supplies. Reduction in HPQC operation voltage can lead to a decrease in the compensation device capacity, power consumptions, and installation cost. The parameter design procedures for minimum dc voltage operation of HPQC are being explored. It is shown through simulation results that similar compensation performances can be provided by the proposed HPQC with reduced dc-link voltage level compared to the conventional railway power compensator. The system rating thus can be reduced. The co phase traction power supply with proposed HPQC is suitable for high-speed traction applications. In this study, the renewable energy sources are used as the supply to the proposed concept. Since the solar radiation is abundant thought the world, we can use these systems any way. Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing power electronic converters. The compensation performance of the proposed active power filter and the associated PV system generation scheme with new control scheme is demonstrated to improve the power quality features is simulated using MATLAB/SIMULINK
