| 摘 要： | 提出了基于双DSP结构的有源滤波与无源滤波相结合的无功与谐波动态补偿原理和方案，设计了无功与谐波自动补偿装置主电路结构与控制系统。采用晶闸管相控电抗器(TCR)的无源滤波器可以增大电源系统的容量，降低成本；而采用基于双DSP结构的有源滤波器可以大大改善滤波性能，并能抑制LC电路与电网之间的谐振，提高补偿系统动态性能。此装置主要解决了补偿中的谐振问题，并使电力系统的功率因数提高到0．9以上，同时有效抑制了供电网的谐波。

| Abstract: | This paper discusses the reactive power and harmonic dynamic compensation principle and their scheme combining passive power filtering with active power filtering based on dual DSPs. The main circuit frame and control system of reactive power and harmonic automatic compensation installation are designed. To use the passive powered filter with TCR can enlarge the capacity of power source system, and reduce its cost. While the reactive power filter based dual DSPs can improve the performance of filtering, and restrain the resonance between LC circuit and electrical network as well as improve the dynamic performance of compensation system. The equipment solves mainly the resonance problem in compensation, makes power factor be more than 0.9, and restrains the harmonic in electrical network effectively. |
