Research Of XML Information Standard Of Substation Equipment State Based On CIM

The maintenance of substation equipment carried out the transition to state maintenance from preventative maintenance. To achieve state maintenance,it need to accumulate a large number of state data of substation equipment and to build an intelligent diagnosis system in order to provide valuable information. In addition,it need to integrate data sources in order to freely and neatly access state data of substation equipment. Standard IEC61968 and IEC61970 enacted by International Electrotechnical Commission (IEC) built a basic model for the equipment objects in electric power system. According to the actual needs in maintenance, information management and state evaluation of substation equipment , unified model of state information of substation equipment was established. The model follows standard Common Information Model (CIM) and builded by ROSE modeling tool of Rational. State information of substation equipment is represented by XML documents. The model builts an integrated information platform for the state evaluate of substation equipment and offers exhaustive state information of substation equipment for apparatus attendant and relevant units.
