The utility model provides an electric wire netting short -term generation schedule check and simulation system, relates to a grid system. At present the electric wire netting staff is not when system's actual load and prediction are inconsistent, takes the short notice unit to reduce or increase that exert oneself or the short notice unit opens the method of stopping, and work load is big, the inefficiency. The utility model discloses a: the information input module, the check analysis module, emulation calculation module: including the 2nd programmable controller and the 2nd data processing device, the 2nd data processing device and a dispatch message input device and a data processing device link to each other in order to obtain data, the 2nd data processing device and the 2nd programmable controller link to each other in order to confirm balanced power plant to use load balancing as the target, revise the initial generation schedule of power plant, hand over data transmission to server. This technical scheme's software implementation is prior art.
