Research And Development Of Graphic Platform Based On RTDS

Real-time digital simulator's modeling interface and running interface are separated. Therefore, a graphic platform similar to EMS style is developed in this paper, which can exchange data with RTDS correctly and real-timely. User can monitor and control the simulation process of RTDS easily with the help of the platform. The function and implementation scheme of the system are analyzed. Wizcon is adopted as interface of the platform. The graphic display, control database and graphic platform variables are generated based on RTDS_DNP points mapping files. Two key technologies are achieved. Output data of RTDS can be displayed in graphic interface real-timely. Furthermore, RTDS can respond to user's operation on the platform. This paper studies and implements the storage of history data and the method of history data displayed as graphics. Besides, the window operation functions are also studied and achieved in this paper. At last, a small power grid model is tested firstly. The testing result shows that the system meets the design requirements. And then the system is used in China Southern Power Grid. Practice shows that the system runs well and it has practical value.
