Distribution system dispatching graphics aided switch generation and management system supported by the platform of distribution management system（DMS） is realized in response to the requirement of the safety， rapidity and convenience in distribution system dispatching planned overhaul and emergency transaction. The system is realized based on the design ideology of graphic guided switching-order generation. The switch rule database depicts the basic frame of graphic guided switching-order generation. The functions such as switch-order generation， safe verification， simulation etc are realized by the cooperation of fast network topology analysis and switch rule. The service conditions in dispatching center of Nanjing Power Supply Company show that the switch-order generation environment is real and reliable because of the integrated design with the platform of DMS and the convenience is achieved for the switch-order generation in graph and switch-order execute in switch-sheet. The safety and rationality of dispatching plan is guaranteed by the safe verification and interactive simulation.
