Study on Optimization of Differential Protection Method of 10 kV Distribution Line Sectional Switches
Differential protection method is a kind of protection technology widely used in power system,which detects and isolates faults by comparing the difference of current,thus protecting distribution lines.Therefore,it is particularly important to study and optimize the sectional switch differential protection method for 10 kV distribution lines.This paper analyzes the main problems faced by existing protection methods in practical application,including misoperation and refusing action,and discusses the potential impact of these problems on the stability of power system.Based on this,a series of optimization strategies of protection methods are put forward to improve the accuracy and response speed of protection methods.Proved by experimental tests,the proposed optimization strategy can significantly improve the differential protection performance of 10 kV distribution lines,which provides strong support for ensuring the reliable operation of power system.
