Research on the application of fiber optic differential protection for 220 kV transmission lines
The rapid development of communication technology has made optical fiber communications increasingly mature.With the increasing demand for power grid reliability,it has become an inevitable trend for optical fiber protection to replace high-frequen-cy protection.The article describes the application and transformation of optical fiber differential protection in the 220 kv line of Dashan 220 kv substation,solving the problem of channel failures that often occur in line protection,providing a reliable and stable optical fiber transmission channel,and providing a reference for the real-time monitoring data of the control center of Shangrao Power Supply Company.
