摘要

介绍了牵引变流器的结构及基本工作原理，分析了无动力回送发电时牵引系统及辅助供电系统的能量流动关系，着重研究了牵引变流器无动力回送发电时的控制逻辑及中间电压保持控制策略，并对回送发电装置的故障诊断和系统保护策略进行了分析。试验结果表明了控制策略的正确性。

Abstract

Main circuit structure and basic working principle of traction converter was introduced. Energy flowing relationship of traction system and auxiliary system when traction system generated power for auxiliary loads in dragged mode was analyzed. The control logic of power-generation device and dc-link voltage control strategy of traction converter in dragged mode was proposed. Fault diagnostic of power-generation device and the system protect strategy were discussed. Finally, the experimental results proved that the proposed method was correct.
