摘要

某电厂 1台 6 0 0MW机组过热蒸汽温度控制采用串级调节

具有很大的迟延性

对此

采用模糊控制与PI控制相结合的控制方式进行了改进。模糊控制在运行工况发生很小波动时即对被调参数有很好的控制作用

而PI调节的积分作用可有效消除静态误差。改进后的调试结果显示

在各种工况下

主蒸汽温度都可控制在 5 30℃～ 5 45℃范围

调节品质优良

Abstract

A cascade control was used to control the superheated steam temperature of a 600MW unit in a power plant

having very big time-delay. It has been retrofitted by using a control mode of fuzzy control combined with PI control. The fuzzy control has good effect to the regulated paramenter even at the time in which only very small operating condition flucturation being occurred

and the integral effect of PI control can effectively eliminate the static error. The debugging result after retrofitting shows

the main steam temperature can be controlled in a range of 530℃～545℃ under various operating conditions

the quality of regulation being excellent.
