To realize real-time control of a power supply station's operation and achieve standardized workflow management and the goal of easy uses， a standardized workflow system for power supply station is presented. In this system， some innovative technologies is used such as reusable component development， graphic driving interface designing， client-side dynamic software upgrading， and simplified role-based access control（RBAC） model. The excellent system has the following advantages: comprehensive business， workflow circulation， faster data transmission， immediate short message service（SMS）， accurate approving location， powerful automatic power line map drawing， exact theoretical line loss calculation， effective operating history recording， and the help in detail. The proposed system has been widely used in engineering application.
