操作主要以人工操作為主,操作過程風(fēng)險(xiǎn)大、強(qiáng)度高,控制精度難把握容易出現(xiàn)裝置運(yùn)行參數(shù)大幅波動(dòng)或?qū)е路怯?jì)劃停車,因此迫切需要一種智能切機(jī)控制功能,實(shí)現(xiàn)切機(jī)過程的自動(dòng)化。有時(shí)候會(huì)存在快速把主備機(jī)切換完成,一旦出現(xiàn)在用機(jī)組設(shè)備故障,需要立即進(jìn)行切機(jī),減少裝置運(yùn)行風(fēng)險(xiǎn),實(shí)現(xiàn)主備風(fēng)機(jī)組一鍵全自動(dòng)切機(jī);CC-TDOB11底板
解決長期存在的煙機(jī)入口蝶閥、煙機(jī)大、小旁通閥控制兩器壓差,響應(yīng)滯后,、同時(shí)存在兩器壓差波動(dòng)比較大的問題;
由于廣西欽州在夏天經(jīng)常出現(xiàn)雷雨天氣,環(huán)境及空氣溫濕度變化大,容易造成主風(fēng)機(jī)組入口工質(zhì)參數(shù)性能瞬時(shí)變化,如果此時(shí)操作工不及時(shí)調(diào)整機(jī)組負(fù)荷,會(huì)造成風(fēng)機(jī)出口參數(shù)變化,影響生產(chǎn);
風(fēng)機(jī)機(jī)組運(yùn)行不在最優(yōu)區(qū)間,電機(jī)功率波動(dòng)比較大,造成非常大的能量浪費(fèi);。
3.切機(jī)原理
以下為備風(fēng)機(jī)切換至主風(fēng)機(jī)的切換步驟:
第一步,各控制回路均投自動(dòng)運(yùn)行,備用主風(fēng)機(jī)組投入送風(fēng)量(FIC40412345) 和總管出口壓力(PI4040)關(guān)聯(lián)加權(quán)性能控制;
第二步,打開主風(fēng)機(jī)組送風(fēng)閥;HONEYWELL CC-TDOB11底板,CC-TDOB11使用指導(dǎo)
第三步,主風(fēng)機(jī)組投入送風(fēng)量(FIC40412345) 和總管出口壓力(PI4040)關(guān)聯(lián)加權(quán)性能控制;
第四步,選擇主機(jī)切入系統(tǒng),開始全自動(dòng)切機(jī)。隨著主風(fēng)機(jī)放空閥(防喘振閥)的逐漸關(guān)閉,主風(fēng)進(jìn)入系統(tǒng),備用主風(fēng)機(jī)的放空閥自動(dòng)逐漸打開,直至切換完成。備用主風(fēng)機(jī)退出系統(tǒng)。
如果采用備用主風(fēng)機(jī)將主風(fēng)機(jī)組切出系統(tǒng),則以上過程中的控制對(duì)象對(duì)調(diào)。

3.2主備風(fēng)機(jī)切機(jī)操作畫面
依據(jù)該操作畫面實(shí)施機(jī)組切換的過程如下:
1、首先把備風(fēng)機(jī)組投入主風(fēng)性能控制防喘閥及靜葉;
2、然后把主風(fēng)機(jī)組投入主風(fēng)性能控制防喘閥及靜葉;
3、最后在主備機(jī)切機(jī)畫面中投入主機(jī)切系統(tǒng)功能;the response of the system to disturbance. In the 20 years since he put forward this theory, many scholars have developed this theory and made it more widely used. 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
