Research and implementation of smart substation configuration file management system based on BPM process engine

Based on the analysis of current conditions and shortages of the configuration files management in smart substation, the problems existing in current conditions are proposed, such as: ICD test technology, SCD test technology, SCD difference comparison technology. In order to meet the demand of the large scale smart substation construction, a solution of building the smart substation configuration file management system based on BPM process engine is proposed. The solution is based on requirements of smart substation operation management, in accordance with the BPMN2.0 standard to establish the business process model, to establish the service node standard, to establish technical support platform for configuration files transfer process of business collaboration and data sharing, closed-loop management of configuration file is achieved. The substation configuration file management system in State Grid Ningxia electric power company successfully verified the availability and practicability of the solution.
