Oriented at the goals of integrated dispatching and control and referring to the developing experience of the dispatchers and operators simulator of North China power grid，a design idea and implementing methods are described.The system has two prominent characteristics，one is the procedure-style and the other is integration of operation.Some new features are elaborated round the two characteristics，including simulation platform，secondary signals simulation，load case，generation control simulation.Meanwhile，the mechanism of data exchange with other simulators and typical training procedure are also dealt with.
