有源电力滤波器的谐波滤除效果分析

Harmonics Filtering Effect Analysis of Active Power Filter

介绍杭州市某枢纽综合楼工程中产生谐波的主要设备,用ABB谐波计算软件Harmonic Analysis from ABB JUMET进行谐波计算,列出1#～4#变压器的各次谐波计算结果。设计选用ABBPQFA-A和PQFA-B型有源滤波器各2台,通过测试滤波前后的相电流和三相电流电压波形,并进行比较分析,得出结论:滤波器的滤波效率明显,超过95%。

Main harmonics sources of one general building in Hangzhou are introduced. Harmonics are calculated by Harmonic Analysis from ABB JUMET. Results of 1-4 transformer are presented, The designer selected 2 ABB PQFA-A active power filters and 2 ABB PQFA-B filters, tested and compared current and voltage waves between fore-filtering and filtering, then draws this conclusion： filtering efficiency are greater than 95%.
