摘要：
In single-phase harmonie current detection algorithm of active power filter (APF), phase-locked loop (PLL) is always used to detect the frequency and phase of grid voltage. As a result, the harmonie detection result is directly affected by the performance ofPLL. In order to solve this problem, combined with the demand for specific harmonie compensation, a new specific harmonie detection algorithm without PLL is proposed. Then the algorithm is analyzed theoretieally. Finally, a simulink model of single-phase active power filter with the new algorithm is buHt. Simulation result proves the effectiveness ofthe new algorithm.
