Research and Implementation of The Fault Information System FOR Relay Protection Based on Cloud Computing Technology

Abstract

With the continuous development of smart grid technology, it is of great engineering application value and urgent practical demand to collect and manage more intelligently the operation and fault information of relay protection in 110kV and below substation. With the introduction of “cloud computing” technology, a cloud platform of fault information with good expansibility, high stability, loose coupling, strong reusability and convenient maintenance could be built up, which is the core of the system construction. In order to make full use of the existing data network channels and network resources in 110kV substation, a fault information system of relay protection, with its sub-station modeling and communication management, is presented based on “cloud computing” technology to realize a more efficient and convenient relay protection exchange between 110kV substation and the dispatching control center.
