Coordinated control system is a complicated multi - variable control system . it is valuable to study the coordinated control system for improving the automatic degree and security economical operation level of thermal power plant 单元机组协调控制系统是一个复杂的多变量控制系统,研究单元机组协调控制系统,将有助于提高火电厂的自动化程度和安全经济运行水平,因此有重要意义。
Then use the artificial neural network to decouple the high coupling object of the coordinated control system . compared with the traditional pid controller , this intelligent control algorithm can achieve better control effect . zhang de - zhen directed by liu chang - liang 并用人工神经元网络对存此强耦合的协调控制系统的被控对象实现单向智能解耦控制,和传统的pid控制比较,这种智能控制算法取得了很好的控制效果。
According to the operation of subcritical reheat controlled circulation drum boiler , this paper analyses the factors which affect the responding speed to unit load , through modifying the coordinating control system , fully using the boiler ability of heat accumulation and other methods , the author puts forward some measures to raise responding speed to unit load 分析了影响中间储仓式汽包炉机组快速响应电网负荷变化的因素,通过对协调控制系统的改进,以及充分利用锅炉蓄热能力等方法,提出了提高机组快速响应负荷变化的几条途径。
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。
These characteristics therefore , make it have wide application prospect . as a part of the crt simulator control system of a dcs power plant , this paper constructs the model of the real control section by using block - structure method and finishes the contrivance of the coordinated control system ( ccs ) , the digital electro - hydraulic control . system ( deh ) and the control system of boiler and turbine 作为开发基于dcs的火电厂全crt仿真机的一部分,本文采用结构化、模块化的方法,对实际控制环节进行建模,完成了仿真机中的协调控制系统和功频电液控制系统以及锅炉、汽轮机控制系统模型的开发。
