Abstract: This paper designs and constructs a whole process,the multiservice training simulation system,which can simulate the dynamic change process of any load curve during the training process and realize multiservice collaborative training simulation.By acquiring the actual data of the production system and the multiservice cooperative operation,the training simulation system can more graphically simulate the dispatching and operation environment of the power system.This paper expatiates on the hardware and software architecture of the simulation system,the production of load lesson plans and the multiservice cooperation.The training simulation system described has been applied in several actual power grid dispatching centers.The simulation data are in agreement with the actual operation data,which effectively supports the training and simulation work of power grid dispatching and operation personnel.
