摘　　要：针对当前我国电气化铁路处于新旧技术的交替阶段、交直机车与交直交机车(动车组)混跑、牵引供电系统谐波含量丰富的情况,介绍了国内外电气化铁路谐波治理技术,重点介绍了指定次谐波电流分频控制研究现状;从电气化铁路的供电特点,分析低次、高次谐波分布;研究了以模块化多电平变换器为主电路拓扑的铁路功率调节器的谐波抑制技术,并将其与无源高通滤波器相结合,提出一种适用于牵引供电系统的谐波抑制策略,实现指定次谐波与高次谐波的抑制。在RT-LAB平台下搭建了仿真模型,仿真结果验证了该控制策略的可行性。Nowadays, China＇s electrified railway technologies were in the alternating stage. AC-DC and AC-DC-AC locomotive （CRH） running in mixture led to rich harmonics in the traction power supply system. Harmonic elimination technology in electrified railway at home and abroad was introduced, and status of specified harmonic current friquency dividing control was focused on; Low-order and high-order harmonic distribution was also analyzed considering of electrified railway power supply characteristics; Combined passive high-pass filter with harmonic suppression technology of railway power controller （RPC） based on a modular multilevel converter （MMC） topology, harmonic suppression strategy for traction power supply system to achieve the specified harmonic and high harmonics suppression was proposed. A simulation model was built in the RT-LAB platform and simulation results showed the validity of the control strategy.
