| 摘 要： | 在建立了电力系统多导体传输线模型的基础上,结合牵引网等值电路的自身特点,利用多导体降阶方法,并通过电力系统电磁暂态仿真平台建立了牵引网的谐波模型。采用某高速客车的典型数据,对牵引网中的谐波电流放大现象和规律进行了仿真分析和验证。通过对牵引网长度、机车位置等因素与牵引网发生谐波电流放大关系的研究,证明了所建模型的正确性。

| Abstract: | Based on the model of multi-conductor transmission line(MTL) and combining with its own characteristic of equivalent circuit of traction network and using order-reduction of multi-conductor,a harmonic model of traction network is built by PSCAD/EMTDC software.Adopting typical data of a certain high-speed passenger train,the phenomenon and law of harmonic current amplification in traction network is simulated,analyzed and verified.Through the research on the relation between harmonic current amplification oc... |
