Beschreibung
Zusammenfassung:	This invention relates to a controller of a reactive compensation device, in which, a working frequency primary voltage signal is input in the controller to control that the primary switch time of a low voltage breaker is a certain time scale of 85-95deg. of the primary voltage signal in related reactive compensation device and a current signal of the controlled compensation branch is input to it to adjust the switch time scale of the related low voltage vacuum breaker based on the diameter and direction of the inrush current when switching to turn the high frequency non-periodic component in the flow value zero and control the cut of the low voltage vacuum breaker when the current signal is zero, which avoids harmonic interference and introduces current signal of the compensation branch for negative feed-back control so as to overcome influence of random factors of time lag.
