| 摘 要： | 高速铁路系统中的交-直机车和交直交机车混跑产生的高次谐波可能会引起牵引网谐振和谐波电流放大，影响高速铁路高速、重载的发展。针对目前高速铁路中的高次谐波谐振和谐波电流放大现象，对谐波电流的放大倍数进行理论推导。首次从数学公式方面推导了考虑滤波器在内的牵引供电系统的谐波模型。基于此模型以牵引网的谐波总畸变率为优化标准，10%畸变率为优化目标，对牵引供电系统中新型阻波高通滤波器接入在首端和末端的参数选择进行优化，提出一种有效选取滤波器参数的方法。研究结果表明滤波器电阻值选取较小时，对滤波器容量的要求越大。

| Abstract: | The high harmonic current which is produced by the AC-DC and AC-DC-AC locomotives of high-speed railway may cause traction network resonance and harmonic current amplification. Aiming at the traction network resonance and harmonic current amplification in high speed railway system, the amplified multiple of harmonic current is derived. The mathematical derivation for harmonic model of traction power supply system considering high-pass filter is derived firstly. Based on this model the parameter and location for the wave-trip high-pass filter in the traction network is optimized with the optimization objective of ten percent of the total harmonic distortion. An effective method to select parameters of wave-trip high-pass filter is proposed. The results show that when the resistance of wave-trip high-pass filter is small, the requirement for the capacity of filter is higher.
