【Abstract】 A specific method of real time load optimized distribution in power plant is presented upon SIS platform. The optimal distribution result was calculated by applying dynamic programming theory on the basis of the comprehensive consideration of the electric system load requirement, the limitation of generator set’s operation, and the characteristic curve of generator sets’ coal wastage obtained by online computation of real time process data in power plant production. Then, by the way of sending the optimal distribution result to CCS of generator sets and feeding back the relative information of power plant via RTU to load dispatching center, the total load optimal distribution among generator sets in power plant can be realized in closed loop control way. Obviously, this kind of power plant control will greatly increase the beneficial result from the economical view.更多还原
