地面自动过分相系统过电压抑制建模仿真研究
|
摘要
介绍了电子开关地面自动过分相系统工作原理,进行了接触网、牵引负荷、过分相装置电气参数计算和系统仿真建模。建立了基于电子开关地面自动过分相的机车带载通过分相区的等效模型。从抑制感应电压、阀组续流等方面综合设计了中性区RC支路关键参数。最后通过仿真验证了本方法抑制过分相过电压的有效性。
The working principle of ground automatic neutral section passing system of electronic switch was introduced. The calculation of electrical parameters of catenary, traction load and phase passing device and system simulation modeling were carried out. The equivalent model of the locomotive passing through the phase separation zone on load was established based on the ground automatic passing of the electronic switch. The key parameters of RC branch were designed by considering suppressing reactive voltage and maintain SCR in on-state. Finally, the effectiveness of suppressing overvoltage was validated by simulation.
