摘　　要：随着高速铁路的高速度、大容量、高密集网络化发展,高速机车引起的牵引网谐波放大、谐振问题越发严峻。为考察牵引网谐波传输特性,在分析谐波传输理论的基础上,利用Matlab/Simulink建立通用的高速动车组(electric multiple unit,EMU)与牵引网的联合仿真模型,通过对高速动车组的不同工况和不同出力下的谐波特性进行仿真分析,验证了模型的正确性。在联合仿真模型的基础上,分别针对机车位置固定、不同机车位置和不同牵引网长度3种情况下的谐波电流传输特性进行仿真分析,结果表明:联合仿真模型较恒电流源模型、恒功率源模型更符合牵引供电系统的实际。该研究结果对降低和避免牵引网谐振带来的危害有一定的参考价值。With the development towards high-speed, high-capacity, high-density cyberization of high-speed railway, harmonics amplification and resonance problems of traction network caused by high-speed locomotive are getting more serious. In order to study the harmonic transmission characteristic of the traction network, Matlab/Simulink software was used to build the united model of electric multiple unit （EMU） locomotive and traction network. The correctness of this model was verified by the simulation of various power in different conditions. Based on this model, this paper analyzed the transmission characteristic of the harmonic currents under three conditions which include fixed locomotive position, different locomotive positions and different lengths of traction lines. Simulation results show that this united model is more practical than consist current model and consist power model. The research sheds light on reducing and avoiding the harm of traction resonance.
