【摘要】 本文以电厂节能减排为先导,结合目前国内600MW主流机组为研究对象,建立了基于经济性、快速性、环保性的多目标厂级负荷优化分配数学模型。结合现场数据获得了机组煤耗率与大气污染物排放特性曲线,进而利用模糊决策理论与模糊层次分析法进行多目标问题的建模。在此基础之上,以动态规划方法作为优化算法,借助MATLAB软件对多目标优化模型进行了算例仿真,并且对仅以最小煤耗率为目标的单目标优化方案与多目标优化方案进行了对比分析。仿真结果表明:采用模糊层次分析法的多目标优化方案在经济性与环保性方面优于单目标优化方案。更多还原

【Abstract】 The precursor of the Energy Saving & Conversion has been behaved as a spur to develop a novel mathematical model combined with charecteristic of economic, rapid and emissions, subjected to a domestic mainstream units of 600MW capacity. Acquirement of field data enables graphical descriptions of both coal consumption rate (CCT) and emimssions. The concept of fuzzy decision-makings and fuzzy analytical hierarchy process (FAHP) was validated to construct the multi-objective load dispatch (MLD) model and based thereon the dynamic programming was adopted. Thus, application on MATLAB was also introduced to the simulation on MLD model. Moreover, we suggest a comparison between the single objective model concerning CCT and the MLD modle using FAHP method. Consequently, the findings show that the MLD model is more preferable on economic and emimssions.更多还原
