Study on the data synchronization mechanism of Dispatcher Training Simulator

Abstract

With the development of electrical power automation, the relationship of DTS (Dispatcher Training Simulator), which is a non-real time system, with real-time dispatching and control system becomes closer than ever before. For enhancing the security of system operation, reducing the adverse effect of DTS data synchronization on the real-time system is necessary. Through exploration of data synchronization and modeling process in different contexts of DTS, potential dangerous factors that exist in the currently used DTS database are exposed. In light of the principle of secure partitioning, a new architecture of DTS is presented to separate the future mode and the real-time mode of DTS into two independent sub-systems. Graphs and models in each subsystem's database are maintained and modified respectively so as not to interfere with the real-time system. Analysis indicates that the influence of DTS on the realtime system can be reduced to a lower level by the proposed architecture, meanwhile, the modeling process in DTS is also simplified. The research findings enhance the security and reliability of DTS system as well as the real-time system.
