摘要

针对轨道车辆需在交流和直流供电制式下穿梭运行的问题，设计了一种对交流和直流供电制式进行诊断的检测电路和控制方法。该方案在轨道车辆牵引、制动、惰行和过分相工况均可准确计算电网电压并判断相应制式，控制列车牵引系统工作于相匹配的状态，当发生异常时，可自动进行诊断和保护。通过现场列车在AC 25 kV与DC 3 000 V供电模式下的实际试验测试，验证了检测电路和控制方法的有效性。

Abstract

In view of the problem that the train need be switched in AC and DC power supply system

an inspection circuit and control method were designed to inspect the AC and DC power supply system. The scheme could accurately calculate the real grid voltage to judge the corresponding system mode under the conditions of the train such as traction

braking

idling and passing the phase separation

and control the traction system of train to work in a matching state. When the abnormality occurs

it could automatically inspect and protect. It was proved that the scheme could effectively improve the safety and reliability of trains through the application and test of existing trains in AC 25 kV and DC 3 000 V power supply system.
