| 摘 要： | 提出了一种新型的综合电能质量控制器（UPQC）。该控制器能满足大容量综合补偿的要求。该控制器由晶闸管投切的电容器组、串联有源电力滤波器和并联有源电力滤波器组成。并联电容器组补偿系统无功，并联滤波器补偿负序电流和谐波电流，串联滤波器补偿谐波电压和不对称电压。文中建立了仿真模型以检验UPQC的补偿效果。仿真结果表明，UPQC的补偿效果是比较理想的。

| Abstract: | A novel unified power quality controller (UPQC) is proposed which consists of thyristor controlled capacitorbanks, serial active power filter and shunt active power filter. The fundamental frequency reactive power of the powersystem is compensated by thyristor controlled capacitor banks, the negative sequence current and harmonic current iscompensated by shunt active filter, the harmonic voltage and unsymmetrical voltage is compensated by serial active filter. To appraise the compensating effect of UPQC a simulationmodel is established. The simulation results show that theproposed UPQC can offer satisfied compensation performance. |
