200MW机组磨煤机调节系统优化设计与应用

Optimum Design of the Adjusting System of the Pulverizer in 200MW Power Unit and its Application

对哈三电厂200 MW机组的磨煤机自动调节系统存在的问题进行了分析。通过对200 MW机组的磨煤机自动调节系统进行优化控制设计.在PID调节、控制输出保护基础上,利用电脑软件实行了4种自动控制方式.实现了机组磨煤机自动调节系统的优化控制.取得了较好的经济效益。

The existing problems of the automatic adjusting system have been analyzed in the paper of the pulverizer in 200 MW power unit in No. 3 Harbin Power Plant. Based on PID regulating and controlling output, 4 kinds of automatic controlling ways have been carried out based on the software and optimum control of the automatic adjusting system has been realized so as to have obtained better profit through optimum controlling design of the auto adjusting system of the pulverizer for 200 MW power unit.
