摘要
针对注入式混合有源电力滤波器中注入支路存在谐波注入能力与无功过补互相矛盾的问题，研发了双谐振注入式混合型有源滤波器。该滤波器具有突出的谐波注入能力，谐波治理效果显著，可补偿大量的电容性基波无功，并能有效防止电网无功过补。以某110kV变电站为例，就其电能质量治理需求提出了相应的治理方案。
There is a contradictory between injecton capacity and reactive power compensation in the injection circuit of hybrid active power filter. Aiming at the problem, this paper develops a double resonance injection hybrid active power filter. This new kind of filter has so great harmonic injection capacity that the harmonic suppression is good enough, and a lot of capative reactive power of the fundamental wave can be compensated, and it is prevented to over compensate the reactive power of networks. Taking a 110 kV substation as an examnle,the paper proposes the treatment scheme for the requirements of its power quality control.
