ABB MODCELL多回路控制器及其在火电厂过程控制中的应用

ABB MODCELL MULTILOOP CONTROLLER AND ITS APPLICATION IN POWER PLANT CONTROL

本文介绍了ABBMODCELL多回路控制器及其技术特点，并结合一国产200MW火电机组的热控系统改造实例介绍其在电厂锅炉控制中的应用情况。应用结果表明，以MODCELL多回路控制器作为控制越来完成电厂热工过程的自动调节、顺序控制及机炉协调控制是行之有效的，以它为基础构成的分散控制系统在火电厂单元机组（200MW及以下）控制中具有推广应用价值。

This paper describes ABB MODCELL multiloop controller and its successful application in the renovation of thermal control system for 200MW coal-fired unit.The result of renovation indicates that it is effective to carryout the autoregulation and sequential control of thermal process and the control of boiler-turbine coordination by meansof MODCELL as the control station of distributed controlsystem in power plant.
