操作主要以人工操作為主,操作過(guò)程風(fēng)險大、強度高,控制精度難把握容易出現裝置運行參數大幅波動(dòng)或導致非計劃停車(chē),因此迫切需要一種智能切機控制功能,實(shí)現切機過(guò)程的自動(dòng)化。有時(shí)候會(huì )存在快速把主備機切換完成,一旦出現在用機組設備故障,需要立即進(jìn)行切機,減少裝置運行風(fēng)險,實(shí)現主備風(fēng)機組一鍵全自動(dòng)切機;CC-TDOB11底板
解決長(cháng)期存在的煙機入口蝶閥、煙機大、小旁通閥控制兩器壓差,響應滯后,、同時(shí)存在兩器壓差波動(dòng)比較大的問(wèn)題;
由于廣西欽州在夏天經(jīng)常出現雷雨天氣,環(huán)境及空氣溫濕度變化大,容易造成主風(fēng)機組入口工質(zhì)參數性能瞬時(shí)變化,如果此時(shí)操作工不及時(shí)調整機組負荷,會(huì )造成風(fēng)機出口參數變化,影響生產(chǎn);
風(fēng)機機組運行不在最優(yōu)區間,電機功率波動(dòng)比較大,造成非常大的能量浪費;。
3.切機原理
以下為備風(fēng)機切換至主風(fēng)機的切換步驟:
第一步,各控制回路均投自動(dòng)運行,備用主風(fēng)機組投入送風(fēng)量(FIC40412345) 和總管出口壓力(PI4040)關(guān)聯(lián)加權性能控制;
第二步,打開(kāi)主風(fēng)機組送風(fēng)閥;HONEYWELL CC-TDOB11底板,CC-TDOB11使用指導
第三步,主風(fēng)機組投入送風(fēng)量(FIC40412345) 和總管出口壓力(PI4040)關(guān)聯(lián)加權性能控制;
第四步,選擇主機切入系統,開(kāi)始全自動(dòng)切機。隨著(zhù)主風(fēng)機放空閥(防喘振閥)的逐漸關(guān)閉,主風(fēng)進(jìn)入系統,備用主風(fēng)機的放空閥自動(dòng)逐漸打開(kāi),直至切換完成。備用主風(fēng)機退出系統。
如果采用備用主風(fēng)機將主風(fēng)機組切出系統,則以上過(guò)程中的控制對象對調。

At present, the research focus of this theory is the control problem in nonlinear systems. In addition, there are some theories about robust control, such as structural outlier theory and interval theory. The application of robust control theory is not only used in industrial control, but also widely used in many fields, such as economic control, social management and so on. With the continuous improvement of people's requirements for control effect, the robustness of the system will be paid more and more attention, so as to make this theory develop faster. Seeing that many brothers and sisters came to ask about the PID controller, I combined with my own understanding and described the concept of PID control and how to design a simple PID controller. The purpose is that interested friends can design a simple
