Abstract
With the development of society, the power grid plays an increasingly important role. As a common accident, leakage current has had a serious impact on the normal operation of the power system. At present, the bridge method and the signal injection method are mainly used to detect DC leakage current. In view of this, this paper is based on a proportional-integral-multimode resonant controller, which determines whether there is leakage current by detecting the output current of the controller. The method is simple, and different times of resonance controllers can be selected according to the actual situation, which is beneficial to make a portable leakage current detection device and has ideal development potential in the future.
