Research on Condition Information Model of Substation Equipment Based on CIM/XML

Power equipment with healthy condition is vital to security and stability of power grid. It is helpful to ensure power network secure and stable to grasp equipment status data immediately and comprehensively and to evaluate equipment status accurately. Information that reflects healthy status of substation equipment is analyzed. The CIM model is extended by following the semantic and grammar of CIM , a unified model for substation equipment condition information is built. The rule for translating extended CIM model into XML document is proposed. By using the extended model and XML technology it is effective to integrate distributed substation equipment status information and to realize retrieving flexible so as to support the higher level unit to made decision of equipment maintenance.
