摘要 针对地铁供电系统中谐波治理和无功补偿问题,对并联型有源滤波器的相关技术进行研究。首先介绍了地铁低压供配电系统方案、分析了地铁动力照明负荷谐波和无功功率特征;然后介绍了并联型有源滤波器的拓扑结构、阐述了其工作原理,建立了三相三线制有源滤波器的数学模型、总结了其两大常见的控制策略;最后在Matlab/Simulink仿真平台中建立仿真模型,通过矢量谐振策略实现了有源滤波器的谐波抑制和无功补偿功能。 To solve the problem of harmonic suppression and reactive power compensation in metro power supply system, the related technologies of shunt active power filter(APF) are studied. Firstly, the scheme of LV supply and distribution system of metro are introduced, the characteristics of harmonic and reactive power of metro power and lighting system are analyzed. Then, the topological structure of shunt active power filter is introduced and its working theory is described, and the mathematical model of three-phase thee-wire APF is established and its two typical control strategies are reviewed. Finally, the simulation mode is built in Matlab/Simulink, and the harmonic suppression and reactive power compensation function of APF have been realized by the vector resonance control strategy.
