摘要
介绍了一种基于FBD法的有源电力滤波器谐波电流检测方法,分析了基波有功电流和基波无功电流、谐波电流、基波负序电流和任意次谐波电流等的检测原理。该方法采用锁相环产生参考电压,将负载电流投影到参考电压上,通过低通滤波器可以准确检测出各种电流分量,并且在电网电压畸变情况下,该方法同样适用。Matlab/Simulink仿真结果证实了该方法的正确性和有效性。
Introduction was made to a kind of harmonic current detection method based on FBD （Fryze-Buchholz-Dpenbrock）. Analy- sis 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.
