摘要
谐波检测方法在有源滤波技术中的研究占有重要地位。串联型有源电力滤波器(SAPF)可较好的补偿电压源型谐波源。基于三相电路广义瞬时无功功率理论,提出了一种新型的在dq0坐标下检测谐波电压的方法,并把该方法应用于SAPF的补偿电路中。理论分析和仿真结果均表明,dq0谐波电压检测方法是正确有效的。
The approach of harmonic voltage detection has an important role in the reseach of APF. The series active power filter （SAPF） can compensate the harmonics distortion caused by voltage type harmonic source This paper presents a new approach of detecting harmonic voltage in dq0 coordinates, based on the generalized instantaneous reactive power, and used in the series active power filter successfully. It is demonstrated by the theoretical analysis and the simulation results that the proposed detecting method of the harmonic voltage is correct and valid.
