The Study of Relay Protection Integrated Automation System

To protect the security and stability of the power system, it is necessary to increase the correct action rate of the relay protection, satisfying the requirement of the power system ’s operation. The implementation of the relay protection integrated automation system enhances the performance and reliability of the relay protection and plays an important role in guaranteeing the network security and stability of the power grid operation. This paper proposed the concept of the relay protection integrated automation system and expatiate the system ’s structure, function and implementation method.
