摘　　要：近几年国内高速铁路牵引变电所陆续出现由于长期过载导致保护线断线,部分变电所地回流过大导致变电所地网发热以及腐蚀严重等问题。本文通过对供电系统及回流系统进行建模和仿真,分析既有分散回流接线方案存在的问题,提出了解决方案,并验证了方案的效果。In recent years,the broken of PW wire suffered from the long-term overload occurred subsequently in the traction substations of high-speed railways in China,and it leads to the problems of heating and severe corrosion of earthing network of substation as the ground return current passes through.The paper,on the basis of the established model and simulation,analyzes the existing problems of the scheme for decentralized return current wiring,puts forward the scheme for the solution.The effectiveness of the scheme is verified accordingly.
