摘要

Abstract

Fires and human casualties caused by single phase-to-ground faults in distribution networks are frequent. However

existing ground fault suppression methods are affected by ground fault resistance. Thus

an adaptive suppression method that seamlessly combines principles of current and voltage suppression is proposed

which has good adaptability to different ground fault resistance. Meanwhile

a multi-criteria ground fault suppression exit strategy matched to adaptive suppression method is proposed to avoid damage of device caused by power backflow

which provides the possibility for reliable and fast exit of the fault suppression device. Experimental results demonstrate effectiveness and advantages of the adaptive suppression method and its exit strategy.
