APF与SVC组合运行分析

Analysis of the APF and SVC Combined Operation

有源电力滤波器(APF)与静止无功补偿装置(SVC)组合运行中会相互作用,导致谐波放大甚至发生谐振。通过分析其导致谐波放大的原因,提出通过对电容器组串联电抗器可以解决谐波放大的问题.通过实验证明该方法能够起到很好的滤波效果。同时,在实验基础上,总结了APF与SVC组合运行的最佳安装位置,进一步为有源电力滤波器工程应用提供指导。

APF and SVC will interact in the combined operation and lead to system harmonic amplification and resonance. The reason of causing system harmonic amplification was analyzed, then put forward series reactors in capacitors to solve this problem. The experiment results show harmonic can be effect filtered after capacitors series reactors.The optimal location for installed was also summarized when APF and SVC joint operation on the base of experiment, which will guide APF further application in engineering.
