Study of Real-time Database Based on Common Information Model

In electric power company, there are some different application information systems for different departments. Lack of unified planning, design, a large number of data information is repeated input, maintenance, waste of a lot of manpower. IEC 61970/61968 common information model (CIM) and component interface specification (CIS) are used for deal with these problems. This paper proposes a real-time database design using CIM. CIM XML files and MySQL database are used for electric power grid data model saving. Based on Light OPC, the real-time data access mode is realized. A prototype is presented and verifies the IEC 61970 the feasibility of application of OPC.
