摘要
汽温控制是火电厂模拟量控制系统的难点,本文阐述锅炉汽温调节系统基本控制结构与特点,分析介绍河南华润电力古城有限公司在串级控制策略下所遇到的问题,并提出引入代表燃料变化的微分前馈和预估控制的解决方案.方案实施后,保证了机组更加安全、稳定运行,提高了机组运行的经济性.
The difficulty of steam temperature control of the rmal power plants lies in steam temperature control. This paperdescribes the basic structure and characteristics of a boiler steam tem perature regulation system, and exam ines theproblem swith cascade control strategy encountered by Henan Resources Power Gucheng Co. solutions, such as diffe rential forw ard feed and pred ictive control. The applications of are safer and run more stably.
