面向通用对象的变电站事件(GOOSE)实时解析和预警系统

Generic object oriented substation event(GOOSE) real-time analysis and surveillance system

GOOSE已经在数字化变电站中广泛应用,但缺乏对GOOSE通信过程有效的分析、监测工具。针对这一空白,提出了GOOSE报文实时解析的步骤和方法,定义了GOOSE传输的正常和异常事件,根据GOOSE实时解析的结果建立了GOOSE通信模型,并在此基础上开发了GOOSE通信预警软件和图形化的人机界面,阐述了预警系统在数字化变电站中的应用情况。GOOSE实时解析和预警系统能够及时发现通信异常,消除缺陷,保证数字化变电站的可靠运行。

GOOSE has been widely adopted in IEC61850 substation projects, but efficient tools to analyze and monitor the GOOSE communication in real-time haven＇t been fulfilled. This paper proposes the methods and procedures to analyze GOOSE packet in real-time and defines normal and abnormal behaviors in GOOSE communication. On top of the outcomes from real-time analysis, and a GOOSE communication model is built, which becomes the base of GOOSE communication surveillance system, and a graphic human interface is also provided. This system has been deployed and achieved the expected results. GOOSE real-time analysis and surveillance system can detect abnormal GOOSE communication behaviors, trace down potential defects, and thus can improve the operation reliability of IEC61850 substation.
