摘 要：介紹了一種基于FBD 法的有源電力濾波器諧波電流檢測方法，分析了基波有功電流和基波無功電流、諧波電流、基波負序電流和任意次諧波電流等的檢測原理。該方法采用鎖相環產生參考電壓，將負載電流投影到參考電壓上，通過低通濾波器可以準確檢測出各種電流分量，并且在電網電壓畸變情況下，該方法同樣適用。Matlab/Simulink 仿真結果證實了該方法的正確性和有效性。

Abstract: Introduction was made to a kind of harmonic current detection method based on FBD (Fryze-Buchholz-Dpenbrock). Analysis was made to active power fundamental current, reactive power fundamental current, harmonic current, negative sequence fundamental current and any sub-harmonic current etc testing principles. The method used phase locked loop to generate reference voltage, to project load current to reference voltage, and to test various current components accurately via low-pass filter, even under conditions of power net voltage distortion. Matlab/Simulink simulation results confirm the feasibility and validity of the method.
Key words: active power filter; FBD method; harmonic detection; simulation
