提出了将基于基波磁通补偿(FMFC)原理的串联混合型有源电力滤波器(SHAPF)应用于中高压系统。介绍了有源电力滤波器的滤波原理、串联变压器的设计,以及逆变器的设计和控制。样机实验结果表明:该有源滤波装置的滤波效果良好、可靠性高,同时该SHAPF的谐波压降对负载供电的影响很小;只投入有源滤波器,而没有投入无源滤波器时,仍然有较好的滤波效果。该技术可应用于电压更高、容量更大的电力系统。

A novel series hybrid active power filter（SHAPF）based on fundamental magnetic flux compensation（FMFC）is proposed to used in the high voltage level electric power system.The working principle of the SHAPF,the engineering design of series transformer and the inverter are introduced.Experimental results of engineering application prove that this SHAPF based on FMFC is good in the harmonic mitigation and reliability.The harmonic voltage on the series transformer has little influence to load voltage waveform.In addition,experimental results also prove that the harmonic mitigation effect is good when there is no passive power filter working.This SHAPF based on FMFC can be used in high voltage and large capacity electric power system.
