制漿造紙行業(yè)工藝規(guī)程復(fù)雜、多樣,對系統(tǒng)和設(shè)備都有著較高的要求,尤其對系統(tǒng)來說,其可靠的穩(wěn)定性和較高的靈活性是保證生產(chǎn)工藝順利進(jìn)行的前提，在森博一期30萬噸項(xiàng)目中，我們采用了HONEYWELL TPS開放型分布過程控制系統(tǒng)，其完善的診斷，組態(tài)工具，模塊化的軟硬件結(jié)構(gòu)，完全滿足了系統(tǒng)的連續(xù)性和穩(wěn)定性要求。在二期擴(kuò)建的100萬噸漿項(xiàng)目中，我們再次采用HONEYWELL 新一代控制系統(tǒng)PKS ，到目前為止，我公司的木片輸送，給水及污水處理已進(jìn)行了應(yīng)用和實(shí)踐，下面將逐一介紹新一代控制系統(tǒng)的結(jié)構(gòu)、布局和控制方案。
1． EPKS硬件組成及結(jié)構(gòu)
EXPERION PKS 過程控制系統(tǒng)是HONEYWELL新一代過程自動化系統(tǒng)，它的功能高于一般的集成控制系統(tǒng)，其中嵌入式?jīng)Q策支持和診斷技術(shù)，為決策者提供了所需信息，其安全組件使安全環(huán)境獨(dú)立于主控系統(tǒng)，也提高了系統(tǒng)整體的安全穩(wěn)定性。
