The Development and Application of Key Technologies of Dispatcher Training System in China Southern Power Grid

There are two critical characteristics of China Southern Power Grid(CSG),namely a great scale grid in a hybrid AC/DC operation mode,and heavy power loads flowing among various provinces.As a result,the key technologies of a new generation of dispatcher training system(DTS) for the Power Dispatching Control Center of CSG include: distributed modeling,online teaching plan automatically creating and efficient joint rehearsal planning.For the distributed modeling,this paper proposes an algorithm that can merge the models of internal and external regions by boundary cutting.For the teaching plan creating,the state evaluation of hybrid AC/DC operation is given while for the rehearsal planning,a mode of " modeling independently,but simulating unified" as well as "dispatching unified,but operating on the spot" is put forward.The new generation of DTS in CSG consists of 879 models of various stations/power generation plans,and has operated for more than four years in the Power Dispatching Control Center of CSG,showing that the key technologies developed for DTS are feasible and efficient.
