投用性能控制后,主風(fēng)機組靜葉由38.8度關(guān)到了28.8度,防喘閥總的輸出由有11.3%關(guān)到了1.5%,主電機功率由17398KW降到了8973KW,主風(fēng)總管流量波動(dòng)范圍在30NM3/min之內。不僅穩定了裝置,而其每小時(shí)節能9000KW,經(jīng)濟效益非??捎^(guān)。
9.備風(fēng)機組投用性能控制效果分析
圖9-1備風(fēng)機性能控制工藝趨勢
由圖9-1所示,各曲線(xiàn)含義分析如下:
綠色曲線(xiàn)是總管流量的設定值;
紅色曲線(xiàn)是總管流量的實(shí)測值;ELAU C600/10/11/1/00電機
黃色曲線(xiàn)是投用主風(fēng)流量性能控制標志;
白色曲線(xiàn)是防喘閥的輸出值;
藍色曲線(xiàn)是防喘振盤(pán)旋點(diǎn);
紫色曲線(xiàn)是防喘振的實(shí)際工作點(diǎn);
淺藍色曲線(xiàn)是備風(fēng)機組靜葉輸出值;
粉色曲線(xiàn)是備電機功率;
可以看出,投用性能控制后,備風(fēng)機組在某一時(shí)段檢測到總管流量下降后,靜葉由51.0度開(kāi)到了57.0度,主電機功率由15594KW升到了15816KW,C600/10/11/1/00使用手冊主風(fēng)總管流量波動(dòng)范圍在30NM3/min之內。后來(lái)工藝人員發(fā)現是因往裝置的安全閥故障自動(dòng)打開(kāi)了,如果當時(shí)沒(méi)有投用性能控制,此事將會(huì )造成主風(fēng)低流量,切斷進(jìn)料。此項功能挽救了裝置非計劃停車(chē),創(chuàng )造了非??捎^(guān)的經(jīng)濟效益。
10.結束語(yǔ)
與傳統催化裂化的操作方式由操作人員手動(dòng)操作完成主備風(fēng)機的切換,自動(dòng)切換控制更加平穩可靠、高效安全、人性化,同時(shí)杜絕了誤操作的可能,從而保證了工藝系統平穩操作的要求。 and adaptive PID, all I know is to use the corresponding control algorithm to adjust the PID parameters in time. Let's take an example. The traditional PID algorithm formula is: ⊿ U (n) = KP [e (n) - E (n-1)] + KIE (n) + KD [e (n) - 2e (n-1) + e (n-2)] U (n) = ⊿ U (n) + U (n-1) e (n), e (n-1), e (n-2) is the deviation between the three set values in history and the process value. This is an incremental PID formula (if anyone doesn't understand what formula increment is, hehe, it may be mentioned later that my writing level is limited and I can't organize the content. Besides, where I think and write, hehe, see the cold). The so-called new PID controller is to use those advanced control laws to properly adjust KP, Ki and Ke according to the difference of E (n). As for how to adjust, hehe, it's too wordy, and it's not what this content should introduce. (the key is that I don't know, hehe, laugh). The great Xia who needs these functions should be my predecessors.
