摘要
为提高区域内各电厂的总体经济性,实现节能降耗的目标,基于区域内各火电厂机组运行数据与试验报告,建立各机组煤耗量及经济收益方程。在此基础上,构建供热机组热、电负荷优化分配不同目标函数。在给定总热、电负荷及相应的边界条件下,分别以相对最小煤耗量和相对最大化经济收益为目标进行优化分配各机组的热、电负荷。结果表明:热负荷、电负荷为上、下同一极值时,两种方案优化分配结果保持一致;其他情况时,不同目标优化方案结果不一致;影响分配结果的因素取决于边界约束条件和机组的热力性能。
To improve the overall economy of the power plants in the region,achieve the goal of energy saving and consumption reduction,based on the operating data and test reports of unit combination of the thermal power plants in the region,the coal consumption rate and economic benefit equations of each unit have been established.On the basis,different objective functions for the optimal distribution of heat or electric load of heating units are constructed.Given the total heat or electricity load and corresponding boundary conditions,the heat or electricity load of each unit is optimally allocated with the relative minimum coal consumption and the relative maximum economic benefit respectively.The results show that when the upper extreme value of heat load and electric load is the same as the lower extreme value,the optimal allocation results of the two schemes are the same,and in other cases,the results of optimization of different schemes are inconsistent,and the factor affecting the allocation results depends on the edge constraint conditions and thermal performance of the unit.
