摘要
文中提出一种基于环保综合评价以解决电网节能环保调度问题,节能环保综合值采用以焓-熵-流量三维热力状态模型表征机组系统的热力循环效率,将其整合为发电煤耗、节能潜力、污染物排放量和回水温度偏差四种因素并赋予权值计算,通过经典进化规划迭代得到电网节能环保调度的最优机组出力分配方案,最后通过合肥电厂#5机组实例表明在电网安全运行基础上,进一步发展节能、环保友好型调度模式的可行性。
A novel environmental comprehensive evaluation is proposed in this paper to solve the problems of grid en- ergy saving and environmental protection dispatching. The comprehensive value adopts the enthalpy entropy flow mod- el which is used to represent the 3D thermodynamic cycle of the power generator. It is integrated four factors of coal consumption, energy saving potential, quantity of pollutant emissions and back water temperature deviation, and then assigned with different weights. The best output scheduling scheme at the station of energy saving and environmental protection dispatching model is obtained by the classical evolutionary programming. Subsequently, the example of fifth unit of Hefei power plant analysis shows the possibility of developing the scheduling model with energy-saving and en- vironmental protection based on safe operation of power grid.
