Implementation of DL/T 890 HSDA Inferface Based on Plant Information Database

DL/T 890 standards stipulated for application program interface of electric power EMS system are equivalent to IEC 61970 international standards.These are used for interconnection,interworking and interoperability between EMS system and other systems of dispatch center.Plant information(PI) database is connected with dispatch supervisory control and data acquisition(SCADA) system data adopting the CIS interface of DL/T 890 standards and DL/T 890 CIM specification exchange dispatch grid model.HSDA interface which is part of DL/T 890 CIS interface is used for high speed data access.This paper introduces DL/T 860 HSDA interface standards and elaborates the way to implement DL/T 890 HSDA interface based on PI database.
