Abstract: By taking the multiservice simulation mode and the multilevel dispatching integration training as the goal and referring to the practice of all-service training simulation system for multilevel power grid dispatching of North China Power Grid,the design idea and implementation methods of the system are described in detail.Focusing on the outstanding characteristics of "multiservice training "and"integration of dispatching",the implementation and control of the whole system are described from the perspective of integration of core dispatching services in the training system,the integrated model and teaching management,the power grid simulation system covering the whole power grid model,teacher monitoring and control.
