Abstract
Besides characteristic harmonics, there are many non-characteristic harmonics in power system. The common passive filter cannot deal with it, which worsens performance and may be results in the resonance to destroy the filter device. According to this problem, the paper presents a novel shunt hybrid active power filter (PHAPF), the principle of PHAPF is analyzed and a complex control strategy for detecting both load harmonics and grid harmonics is proposed. Simulative results show that the PHAPF has excellent performance and application outlook??
