200 MW及以下容量机组除氧器和凝汽器水位多变量模糊控制系统

摘要

This paper analyzed the water level characteristics of deaerator and condenser of 200 MW and below thermal power units. By combining with the retrofitting project of No.4 unit in Yangzhou Power Plant a novel method of multivariable fuzzy logic control was proposed which was very suitable for deaerator＇s and condenser＇s level control of 200 MW and below units. The results of more than two years＇ running show that the fuzzy control system features good control performance being able to ensures the long-term stable operation of deaerator＇s and condenser＇s water levels.%对200 MW及以下容量机组除氧器和凝汽器水位被控对象进行分析,结合扬州发电有限公司4号机组的实际工程改造,提出一种适合于国内200 MW及以下容量机组除氧器水位和凝汽器水位的多变量模糊控制方法。实际运行表明,该控制方法具有优良的控制品质,确保了该控制系统长期稳定投入。
