摘　　要：为保证串联混合型有源电力滤波器(SHAPF)在高压大功率场合下的正常运行,同时改进其滤波效果,提出了一种应用于高压大功率系统的SHAPF。将变压器次级的逆变器化解为三组单相全桥逆变器,同时将变压器次级设计为两绕组,反相注入系统基波电流,使串联变压器初级对谐波的阻抗变大。在一套10 kV样机上进行实验,验证了这种基于基波磁通补偿原理的SHAPF有良好的滤波效果和可靠性,并且完全可推广应用在更高电压等级及更大功率的电力系统的谐波抑制中。In order to ensure series hybrid active power filter（SHAPF） to operate normally in a high-voltage and high capacity system, and to improve the filtering effect, a SHAPF applied into high-voltage and high-power system is presented.This SHAPF separates the three-phase inverter which is connected to the secondary of the transformer into three sets of single-phase bridge inverters.And the secondary winding includes two windings.In this condition,the fundament current is imported into the secondary in reversed-phase to increase the impedance of the series transformer to harmonic current.As the tests based on a 10 kV prototype proof,this SHAPF which based on fundamental magnetic flux compensation has a good filtering effect and reliability.This set of device can be promoted to harmonic suppres- sion of higher voltage and higher power system.
