PURPOSE:To ensure a satisfactory load following control, by controlling a power plant by predicting the future working state of the thermal power plant based on a load command. CONSTITUTION:A central feed command center 500 predicts the load demand of the power system and decides the load distribution of a thermal power plant 400 at the present point and a near future point. Then the load distributions of the present and near future points are delivered to each power plant in the form of the load comands of the present and near future points. A prediction control system 100 incorporated with model controls a system of a combination of a master controller 200, a subcontroller 300 and the plate 400. Thus the system 100 containing a model predicts the near future condition of the controlled system based on the load command given from the center 500. Based on the result of this prediction, an optimum control is given to the controlled system. This ensures a satisfactory load following control. |
