摘　　要：为了兼顾谐波治理需求,同时避免传统无源滤波器容易引起系统谐波谐振的问题,提出一种基于混合型有源滤波器(HAPF)的新型静止无功补偿器(SVC)结构,并量化推导了有源滤波部分的谐波控制系数的合理设计范围。在此基础上,提出一种基于同步旋转坐标和改进广义积分控制的HAPF控制策略,从频率特性角度剖析了闭环跟踪精度及控制稳定性,并进一步校核新型SVC的谐振抑制能力。最后,搭建新型SVC样机实验平台,验证了所提方法的可行性和有效性。In order to take into account the demand of harmonic control and avoid the problem of system harmonic resonance caused by traditional passive filters,a novel static var compensator(SVC)structure based on hybrid active power filter(HAPF)is proposed,and the reasonable design range of harmonic control factor of active power filter is qu-antified.On this basis,an HAPF control strategy based on synchronous rotation coordinates and improved generalized integral control is proposed.The closed-loop tracking accuracy and control stability are verified from the perspective of frequency characteristics,and the resonance suppression capability of the novel SVC are further analyzed.Finally,a novel SVC prototype platform is established to verify the feasibility and effectiveness of the proposed method.
