Abstract :
In order to incarnate area wide protection in engineering application and improve the capability of relay protection, the paper refers to regional intelligent protection system. In compared with wide area protection, regional intelligent protection system pays attention to improving the capability of relay protection by using regional power network information. In regional intelligent protection system, the relay protection devices could obtain more abundant information from regional power network than local area, including fault direction information, breaker information. And the paper also introduces some regional protection means by using the information, which is useful to improve the reliability of relay protection.
