Abstract

Abstract:

As an important measure to ensure the safe operation of power system, relay protection has many functions. It is easy to realize the automation of power supply system by relying on relay protection. In view of the different operating status of the plant, in addition to mastering the basic relay protection setting method, it is also necessary to analyze, compare and select the appropriate working conditions. This paper analyzes the relay protection setting of 10kV power supply line in petrochemical plant with an example.
