| Since 1999, China’s first 500-kilovolt substation integrated automation put into operation, with the development of computer technology, big data network technology, coupled with aging equipment, hardware and software upgrades and other factors fast, comprehensive domestic large number of 500 kV substation automation system into the replacement period. While gradually advancing grid "three five" construction, but also cause a lot of 500-kilovolt substation will be integrated automation system reform and access to centralized monitoring center.In this paper, the current 500-kilovolt substation automation system problems, analyze the substation automation system transformation of sense to explore the transformation substation automation data network structure, application and other issues IEC61850 data protocols Statute. Research on Jiangxi Power Grid 500-kilovolt substation automation system Yongxiu transformation plan designed to transform simulation test after test integrated automation systems analysis to verify the reliability of the system and ensure that the new, the old system a smooth transition. Discussion on the implementation of the process 500-kilovolt substation automation system transformation, analyzed and discussed the 500-kilovolt substation automation system upgrading construction technical measures, the danger point and countermeasures. Yongxiu combined 500-kilovolt substation automation system transformation, analyzed 500 kilovolt substation automation data access centralized monitoring center, once the equipment on-line monitoring, intelligent inspection robot and other new technologies in the 500 kV substation automation system implementation Application and so on.Through the 500-kilovolt substation integrated automation system for research, carried out 500-kilovolt substation automation system Yongxiu transformation practical applications, the initial realization of intelligent operation and maintenance of 500-kilovolt Substation. |
