The System Design and Simulation Research of Low Voltage Lockout over Current Protection about Transmission Line

Abstract:

Electricity has become the foundation of the national economy. Electric power security concerns the vital interests of people , economic development and social stability. Power system relay protection and automatic device is a reliable guarantee for safe and stable operation of power system .On the basis of the over current protection , low voltage lockout over current protection can improve the reliability of protection action by using low voltage lockout condition. The article describes the structure of low voltage lockout over current protection system and working state of it.The simulation results indicate that the system can correctly reflect the working state of protection, and it is conducive to understand the working principle of low voltage lockout over current protection . So, the system has practical application value.
