Abstract

According to the twenty-five instructions about anti-accident measure and the technical code for relaying protection and security automatic equipment, the principle and significance of dual-configuration relay protection on EHV networks is put forward. The characteristics of dual-configuration relay protection in several aspects are researched and analyzed, such as DC power supply, alternating current, alternating current voltage, transmission channel and so on. And some methods to solve the problems are present. Specific aspects of dual-configuration of relay protection are discussed and counter measures are proposed. It has great significance to provide high security and stability for power system
