摘要
文章提出了一种基于 ip、iq运算方式的改进型谐波电流检测方法 ,该方法成本低 ,检测精度高 ,无论电源电压是否畸变均能准确地检测出谐波电流 ,谐波补偿效果好 ,主要部件参数对谐波检测精度的灵敏度低。
An improved harmonic current detecting method is presented on the basis of i p? i q calculating modes. Low cost and high detecting sensitivity is its character. Whenever source voltages are distorted, this method can precisely detect harmonic current, the compensations effect of harmonic current is good, and the sensitivity of main parts parameter to the harmonic current is low. Simulation results demonstrate the validity of this method.
