摘　　要：电气化铁路中各种电力机车产生了大量的谐波,严重影响了电网的电能质量。有源滤波技术是目前谐波治理的主要方法,分为谐波检测和谐波补偿2部分。选择韶山SS9型电力机车作为谐波治理的研究对象,首先简要分析了该机车主电路结构和控制策略,然后介绍了基于瞬时无功功率理论谐波检测方法和基于滞环比较控制的补偿电流产生电路,最后用Matlab/Simulink建立了SS9型电力机车的仿真模型并对其谐波进行检测和补偿。仿真结果表明有源滤波技术可以很好地治理SS9型电力机车的谐波,具有较高的理论和实际价值。The widely application of all kinds of the electric locomotive of electrified railway produced a lot of harmonic, which influence electrical power quality. So far,active power filter technology is the main method for harmonic control, including harmo,lic detection and harmonic compensation. This paper takes Shao Shan （SS） 9 electric locomotive as a research object, analyses the structure of tile circuit and control strategy, and introduces harmonic detection method based on instantaneous reactive power theory and harmonic compensation method based on hysteresis control theory. In the end,the paper establishes the simulation model of SS9 and carries on its the harmonic detection and compensation using Matlab/Simulink. The results show that the active filter technology can solve the harmonic problem in SS9 electric locomotive.
