动态寻优法在供热机组热电负荷优化分配中的应用

Application of Dynamic Optimization Method in the Optimization of Heat and Power Load Distribution of Heating Unit

简要概述了热电机组负荷最优分配在工程应用中存在的问题,采用全厂和机组运行工况表描述供电、供热能耗特性曲线,通过最优工况动态寻优方法求解负荷优化分配问题,提高了方法的工程适用性。以某2×200 MW+2×300 MW热电厂的全厂热电负荷分配问题为实例,取得日标煤消耗量下降36.91 t的节能效益。

The problems encounted in the application of heating unit load distribution optimization is simply generalized. The curves of energy consumption on heat supply and power supply were adopted to reach optimal load distribution by using dynamic optimizing method. Practically, the program of load distribution for heat supply and power supply was optimized in a 2 ×200 MW＋2 × 300 MW thermal power plant, which obtained favorable energy-saving benefits with decrease of coal consumption by 36.91 tons per day.
