本文介紹了余熱電站集散型控制系統(tǒng)的構(gòu)成和設(shè)計(jì)要點(diǎn)。該系統(tǒng)由監(jiān)控層和過
程控制層并配以少量現(xiàn)場(chǎng)儀表和控制設(shè)備構(gòu)成，可實(shí)現(xiàn)對(duì)兩臺(tái)鍋爐和一臺(tái)汽輪機(jī)——
發(fā)電機(jī)組及其輔助設(shè)備的自動(dòng)控制和集中監(jiān)控。文中還對(duì)循環(huán)流化床鍋爐重要回路的
控制策略做了詳細(xì)的描述。

Abstract : The structure and design essentials to this electric station using remain heat of the
distributed control system is introduced in this paper. The system is composed of supervise
and control layer, process control layer with a few field meters and control instruments. The
DCS can realize supervising of the technology process, automatic controlling of two boilers
and a steam turbine–generator group with assist equipments. The control tactics of
important loop about cyclic mobile layer boiler is described in detail.
