摘　　要：针对传统有源滤波器(APF)只能治理本地谐波源的不足,提出了基于虚拟谐波电阻的谐波主动防御系统(HADS)。分析了HADS治理配电网谐波的原理,建立了HADS仿真模型,提出了谐波功率最大化和谐波畸变率最小化两种控制策略,并研制工程样机进行了工程示范应用。研究和实验证明,HADS能够有效降低区域谐波污染,可以成为新型电力系统下的区域谐波治理手段之一。Aiming at the deficiency that the traditional active power filter(APF)can only control the local harmonic source,a harmonic active defense system(HADS)based on virtual harmonic resistance was proposed.The principle of harnessing harmonics in distribution network by HADS was analyzed,the HADS simulation model was established,and two control strategies of maximizing harmonic power and minimizing harmonic distortion rate were proposed.An engineering prototype was developed for engineering demonstration application.Theoretical and experiments prove that HADS can effectively reduce regional harmonic pollution and become one of the regional harmonic control means under the novel power system.
