基于YNvd平衡变压器的电铁背靠背SVG补偿系统研究
Electrified railway back-to-back SVG compensation based on YNVD balance transformer
摘要
Abstract
According to the problems of negative sequence,reactive and harmonic caused by traction power supply system,back-to-back SVC compensation scheme based on balance transformer is proposed. Two back-to- back SVGs together use a DC capacitor,when the loads of two aims are different,active power can pass through the middle of the DC capacitor and then the loads can be nearly equal,so the loads can be equivalent to symmetrical load at the primary side of the transformer so as to salve negative sequence problem and also to solve harmonic and reactive power problems caused by the traction load. Simulation result of the system is presented to verify the system feasibility.关键词
