基于优化排污函数的节能发电调度方案

Energy-Saving Power Dispatch Scheme Based on More Precise Emission Function

针对目前节能发电调度的排污函数较为粗略的问题,利用ASPEN PLUS对燃煤电厂的锅炉燃烧流程进行模拟,通过SPSS软件对燃烧所产生的污染物进行回归分析,得出更加细化的排污函数。利用该函数,以发电产生的环境成本及燃料成本最优为目标,建立调度模型,并对包含26个节点、6台发电机的系统进行算例分析,验证了该排污函数和调度方案的有效性。

This paper aims at the low accuracy of emission function and uses ASPEN PLUS to simulate the process of boiler com-bustion. Then a more precise emission function is obtained from regression analysis of the data from boiler combustion by SPSS. The authors establish a dispatch model based on the more precise emission function by using the lowest environmental cost and fuel cost as the objective. Simulation shows the dispatching model based on more precise emission function is more effective in emission reduction.
