Abstract
This paper studies the optimal configuration and setting scheme of hierarchical protection in distribution network.This paper first introduces the present situation and challenges of distribution network protection,then expounds the concept and advantages of hierarchical protection,and then puts forward an optimal configuration scheme based on hierarchical protection,including the layout of protection devices,the formulation of protection strategies and the calculation of setting values.The feasibility and effectiveness of the scheme are verified by simulation.The experimental results show that this scheme can significantly improve the protection performance of distribution network,reduce the power outage range in case of fault,improve the reliability and stability of power supply,provide new ideas and methods for optimal configuration and setting of distribution network protection,and have great significance for improving the operation safety and stability of distribution network.
