摘要
利用瞬时功率的概念提出了一种对三相交流电量实时采集与检测的方法,这种方法能实时检测出电流带有谐波时的基波和谐波分量,并且这种方法实时性好,精度较高,硬件电路简单。
This text exploits the concept of the moment power and put forward a kind of method to collect and examine three mutually the alternate current qua ntity,this method can examine the fundamental component and harmonic component w hen the current has harmonics, and this kind of method has no delay and the accu racy is higher, the hardware electric circuit is very simple .
