摘要
针对含有大量无功功率和谐波较高的场合,提出了由有源电力滤波器(APF)和电容器组成的混合补偿系统。通过负载电流检测和复合电流检测的方式分析了混合系统的幅频特性。通过对APF单独补偿、及混合系统补偿进行仿真,验证了混合补偿系统的有效性。在钢厂的实际应用验证了混合补偿系统可行性。
A hybrid compensation system of active power filter and capacitors is proposed for large amounts of reactive power and harmonic situation. Amplitude frequency characteristics of the hybrid system are analyzed by means of load current detection and composite current detection. Through to the simulation of APF compensation and hybrid system, the validity of the hybrid compensation system is verified. The feasibility of hybrid compensation system is proved by the practical application in the steel mills.
