On the Operation and Maintenance Technology of Power System Rrelay Protection
Relay protection is an indispensable security measure in power transmission and distribution.As the first security defense line in the power system,it can effectively protect the abnormal conditions of lines and substations and provide guarantee for the safe and stable operation of the power grid.In order to ensure the normal function of relay protection,it is necessary to pay attention to daily operation and maintenance.This paper discusses the common faults of power system relay protection,analyzes the operation requirements of relay protection in reliability,rapidity,selectivity and sensitivity,and probes into the application key points of relay protection operation and maintenance technology,in order to provide reference for the application and management of relay protection devices.
