摘要:
针对高速列车运行过程中出现的内部过电压现象,以车载自动过分相过电压和升降弓过电压 2 种情况为例,分析过电压产生原理及其影响因素,并建立仿真模型进行验证。为抑制高速列车内部过电压,提出在中性段并联阻波高通滤波器、采用贯通式同相供电系统以及选取合适的车顶电压互感器 3 种措施。结果表明,高速列车内部过电压与动作时刻接触网电压相位、电压互感器阻抗有关;通过仿真验证,所提出的 3 种过电压抑制方法均能有效降低过电压。
Abstract:
Aiming at the internal overvoltage phenomenon during high-speed train operation, the overvoltage formation mechanism and its influencing factors were analyzed by taking the case of the overvoltage in passing neutral section and the overvoltage of pantograph raising and dropping, and a simulation model for verification was built. In order to reduce the internal overvoltage of high-speed train, three measures of parallel blocking high-pass filter in neutral section, adopting advanced co-phase traction power supply system and selecting suitable roof voltage transformer were proposed. The results showed that the internal overvoltage of the high-speed train was related to the voltage phase of the catenary at the time of operation and the impedance of the voltage transformer, the three overvoltage suppression methods proposed could effectively reduce the overvoltage with simulation.
