摘要/Abstract

摘要：

为满足日益严格的环保要求,同时伴随着机组利用小时数的下滑,火力发电厂盈利空间不断被压缩,电厂正在通过优化运行方式、设备技术改造等方法提高生产效率。利用动态规划（DP）算法,使用计算机编制程序确定磨煤机最优运行方式可以降低制粉系统耗电量,提高机组供电效率,该节能降耗的思路和方法具有一定的推广价值。

关键词: 节能降耗, 动态规划算法, 制粉系统, 运行优化

Abstract:

To meet the more and more strict requirement of environmental protection, and with the reducing of unit utilization hours, the profit space of fossil fired power plant has been squeezed continuously, power plant is improving production efficiency by way of operation mode optimization and technological transformation of equipment. Through dynamic programming algorithm, combining computer programming, optimizing the operation mode of the pulverizing system can reduce the working energy consumption, improve power supply efficiency of the unit, the method and thinking of energy saving has extension value.

Key words: Energy saving, dynamic programming algorithm, pulverizing system, operation mode optimization
