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。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 occurred in traction network and the factors such as the length of traction network and the location of locomotive, it is proved that the built model is correct.
