摘要
针对用于高压直流输电的无源—有源电力滤波器混合型的滤波系统,采用滞环瞬值比较控制方式得到控制有源电力滤波器的 PWM 信号。文中分析了其基本工作原理,给出了相应的控制系统,并给出了直流有源滤波器系统谐波补偿性能的仿真结果和实验结果。
For passive-active hybrid filter system in HVDC system,the hysteresis compare control approach is used in order to get the PWM signal for active DC filter.The basic principle of active DC filter is analyzed and the corresponding control system is presented in the paper.The simulation and experiment results on harmonic compensation perfor- mance of active DC filter is also introduced.
