With the aid of these blocks , it is convenient and flexible to make up different kind of automatic - controlled simulating system and so to accomplish different kind of automatic adjusting task . this paper is focused on the construction of the simulation model of ccs by using the contrived control section model . the ccs employs advanced direct energy balance control strategy and can simulate different running patterns such as turbine following boiler pattern , boiler following boiler pattern , etc . two independent control loops : power control and frequency control , are used in the contrivance of deh and they are separately corresponding to the normal condition and the abnormal condition 本文利用开发的控制环节模块，着重建立了协调控制系统的仿真模型，该协调控制系统采用了先进的直接能量平衡控制策略，并能仿真机跟炉、炉跟机、机炉协调、手动以及定压和滑压等运行方式；开发的功频电液系统模型采用了功率控制和频率控制两个独立的控制回路，能够在机组正常运行和启停时对汽轮机进行控制。
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。
