the strategy of intelligent control is studied in this paper and applied on unit coordinated control system, which is designed, ran and applied in menda power plant 本文论述智能控制策略的研究及其单元机组协调控制系统中的应用,并具体在内蒙古达拉特旗发电有限公司2#机组的协调控制系统中的设计、调试、投运和实现。
in this paper the algorithms of multi-variable dynamic matrix control ( mdmc ) and pair of value dynamic matrix control ( pvdmc ) and their applications are proposed on the unit coordinated control system 本文的主要工作是研究多变量动态矩阵控制算法,提出多变量双值动态矩阵控制算法,并把它们应用于单元机组协调控制中。
the paper is committed to the research on the application of fault diagnosis and fault tolerant control in the modern power plant . the new schemes of fault diagnosis both for boiler water level control system and unit coordinated control system are presented; moreover, based on the lqg strategy, a scheme of fault tolerant control for unit coordinated control system is also proposed 电厂热工控制系统的安全运行已经成为人们日益重视的课题,在这种背景下,本文致力于故障诊断与容错控制在电厂热工控制系统中的应用研究。主要内容是针对电厂锅炉汽包水位控制系统和电厂单元机组协调控制系统提出两种故障诊断的新方案;并且把lqg控制策略应用于单元机组协调控制系统,提出了协调控制系统的主动容错控制方案。
