Design of Integrated EMS/DTS System Based on IEC 61970

IEC 61970 is one of the most important standards of the new-generation EMS/DTS system. This paper proposes the key technical issues in developing the EMS/DTS system based on IEC 61970. The methods for implementing the database platform, CIM model. EMS API and heterogeneous supporting system are discussed. First, a heterogeneous database platform composed of database and soft-bus is proposed. Then three types of database management modes are adopted in the background database to store, retrieve and process data, in which the architecture guarantees the openness and efficiency of the system. Then the soft-bus, based on the real-time CORBA middleware, supports the CIS standard in an all-round way. Secondly, a WYSWYG(What you see is what you get) method for power system modeling, firmly compliant with CIM, is presented. Furthermore, different strategies are applied to wrap the legacy EMS/DTS modules. It is shown by test results that this strategy is feasible.
