摘　　要：循环水系统作为火电厂的重要组成部分,其优化问题已引起人们的高度重视。针对火电厂循环水系统高能耗问题,根据某火电厂提供的数据,建立了其循环水系统发电量与耗电量差额的数学模型,用有约束非线性规划的方法解出其最优解。仿真结果表明,该优化模型和求解算法能够找到最优循环水量和最佳真空,使水泵高效运行,以节约电厂耗电。Optimal control of circulating water system is an important item in energy saving of power plant. As to the high power consumption of circulating water system, we establish a mathematical model of circulating water system, according to the data of a power plant, which depicts the difference between the generating capacity and power consumption, and obtain its optimal solution based on the method of constrained nonlinear programming. The simulation result shows that the method of constrained nonlinear programming can effectually get the optimal solution. It makes pumps more effectual and saves the power consumption.
