摘要:溫度是發電廠中監測設備狀態的重要參數之一,涵蓋從系統到設備的每個角落。隨著DCS系統的廣泛應用,溫度參數不再僅僅局限于監視,已被廣泛運用到保護回路和自動調節回路中。本文結合電廠實際情況,介紹如何利用DCS系統的強大計算和邏輯判斷能力,對溫度拒動和誤動邏輯做出更合理的設計,實現溫度保護、溫度連續預測等功能。
關鍵詞:DCS;溫度保護
Abstract: Temperature is one of the important parameters to monitorequipment status in power plant, covering every corner from systemto equipment. With the wide application of DCS system, temperatureparameters are not only limited to monitoring, but also widely usedin protection circuit and automatic regulation circuit. Based on theactual situation of power plant, this paper introduces how to use thepowerful calculation and logic judgment ability of DCS system to makea more reasonable design for the logic of temperature misoperation andmisoperation, so as to realize the functions of temperature protectionand continuous temperature prediction.
Key words: DCS; Temperature protection
