摘要
对轨道交通供电系统中电力谐波的产生原因、构成、危害及抑制措施进行分析;论述混合型有源电力滤波器的结构和工作原理,讨论谐波检测、脉宽调制(PWM)控制技术及设备容量的解决方法等。仿真研究、样机验证和工程应用表明,有源电力滤波器可以有效地解决谐波治理和无功补偿,满足轨道交通供电系统的电力质量要求。
This paper analyzes the causes of harmonics in rail transit power supply system and discusses the harmonic components and effects on the machine and electricity systems. After analyzing the structure and working principles of hybrid active power filter （HAPF）, author emphatically discussed the detection of harmonic, control technology of pulse-duration modulation （PWM）and the solution of equipment capacity. Simulation results, prototype validation and engineering application show that the designed HAPF can effectively eliminate harmonics and compensate reactive power, and can meet the quality requirements of the rail transit power supply system.
