Integration Method and Test of IEC 61850 Client in Integrated Supervision and Control System of Substation

Abstract

Currently, the information exchange between various systems in substation is difficult, and the scheme of integrated supervision and control system of substation can effectively promote the smooth flow of information in the substation. In this paper, by analyzing the Communication architecture of integrated supervision and control system, the devices that communicate following the IEC61850 standard in station layer are given, which all need to integrate IEC61850 client. Then an integration method of IEC61850 client is proposed, providing unified IEC61850 client for different devices in integrated supervision and control system of substation to reduce the risk of interoperability failure because of using different IEC61850 clients. While a communication test is conducted using IED simulator and communication gateway simulator to verify the feasibility of the proposed integration method.
