Design and development of distribution grid defect management information system

The present distribution grid management information systems emphasize information acquisition and management,but not pay sufficient attention to the workflow management.Based on the present ways of developing distribution network management information system,this paper introduces workflow management technology,and puts forward the closed-loop workflow.Combining the design and construction of management information system for power supply production inside Tianjin Electric Power Co.,it expounds the workflow model based on closed-loop,systematically introduces the overall structure of distribution grid management information system.According to the workflow model,the logic control of the closed-loop workflow is designed in this paper,and the lectotype and design of the system platform and database are described.It is proved that the system implements the closed-loop control and progress monitor of the defect management.
