Research on improving quality of electricity energy in train's traction

Abstract

Based on the analysis on the contradiction between the designing of thyristor controlled series capacitor(TCSC) and static var compensator(SVC) in same circuitry, how to coordinate control dynamic parallel capacitor compensation and series capacitor compensation in power supply system of train's traction is studied. For saving energy, an optimal control strategy about capabilitys of compensations and a qualitative-quantify control way for dynamic parallel capacitor compensation are advanced. The system can improve effectively the rate and precision of compensating, and has a fine performance to change the compensation when load changes, so it has great significance for making over our electrization railway.
