解決長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(yīng)滯后,、同時存在兩器壓差波動比較大的問題;
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)機組入口工質(zhì)參數(shù)性能瞬時變化,如果此時操作工不及時調(diào)整機組負(fù)荷,會造成風(fēng)機出口參數(shù)變化,影響生產(chǎn);
風(fēng)機機組運行不在最優(yōu)區(qū)間,電機功率波動比較大,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(quán)性能控制;
第二步,打開主風(fēng)機組送風(fēng)閥;HONEYWELL CC-TDOB11底板,CC-TDOB11使用指導(dǎo)
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(quán)性能控制;
第四步,選擇主機切入系統(tǒng),開始全自動切機。隨著主風(fēng)機放空閥(防喘振閥)的逐漸關(guān)閉,主風(fēng)進入系統(tǒng),備用主風(fēng)機的放空閥自動逐漸打開,直至切換完成。備用主風(fēng)機退出系統(tǒng)。
如果采用備用主風(fēng)機將主風(fēng)機組切出系統(tǒng),則以上過程中的控制對象對調(diào)。

3.2主備風(fēng)機切機操作畫面
依據(jù)該操作畫面實施機組切換的過程如下:
1、首先把備風(fēng)機組投入主風(fēng)性能控制防喘閥及靜葉;
2、然后把主風(fēng)機組投入主風(fēng)性能控制防喘閥及靜葉;
3、最后在主備機切機畫面中投入主機切系統(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
