Mabaadi'da Shaqada ee Nidaamka Xakamaynta Toos ah ee Dab-dhaliyaha Naaftada

Waqtigan xaadirka ah, kobaca joogtada ah ee ganacsiga ganacsiga, isticmaalka tamarta maalinlaha ah ee xarunta xogta ayaa sidoo kale muujinaysa isbeddelka koritaanka isku mar ah.Marka korontadu xumaato, hal matoor naafto ah ma dabooli karo baahida awoodda kaydinta xarunta xogta gabi ahaanba, sidaas darteed waxay u baahan tahay awood dheeraad ah.Unugyadu waxay u socdaan is barbar socda.Si loo hagaajiyo waxtarka dhaqaale iyo isku halaynta nidaamka hawlgalka nidaamka awoodda, tani waxay u baahan tahay in nidaamka xakamaynta macquulka ah ma aha oo kaliya u baahan unugga laftiisa si uu u yeesho waxqabad wanaagsan, laakiin sidoo kale wuxuu u baahan yahay cutub kasta si macquul ah u xambaaro culeyska firfircoon iyo falcelinta ee hoosta hoose. nidaamka.Shuruudahani waxay si wada jir ah uga muuqdaan nidaamka xakamaynta xawaaraha ee dhaqdhaqaaqa ra'yiga iyo nidaamka xakamaynta korantada ee koronto-dhaliye isku xiran .

1. Xakamaynta daadinta.

Si loo hubiyo xasiloonida isbarbar-dhigga hawlgalka dab-dhaliye ee naaftada, xakamaynta qulqulka ayaa inta badan la qaataa, taas oo ah, xakamaynta qulqulka P/f iyo xakamaynta qulqulka Q/V ayaa loo isticmaalaa si loo helo soo noqnoqoshada xasilloon iyo danab.Habkan xakamaynta ayaa saameeya soosaarka tamarta firfircoon ee cutub kasta.Xakamaynta goonida ah ee leh awoodda falcelinta, iyada oo aan loo baahnayn isgaadhsiinta iyo isuduwidda u dhexeeya cutubyada, si loo gaaro xakamaynta isku-filka ah ee u dhexeeya cutubyada, iyo in la hubiyo dheelitirka sahayda iyo baahida iyo xasilloonida soo noqnoqda ee matoor naaftada dhigay nidaamka barbar socda.

Kantaroolka dhicisku wuxuu qaataa korantada iyo kantaroolka laba-loop ee hadda jira.Wareegga gudaha ee hadda wuxuu leeyahay xawaare jawaab celin firfircoon oo degdeg ah, kaas oo loo isticmaalo in lagu wanaajiyo tayada korontada ee qalabka wax dhaliya.Xakamaynta loop-ka dibadda ee danabku waxa uu leeyahay xawaare jawaab celin firfircoon oo gaabis ah, kaas oo xakamayn kara tamarta wax soo saarka ee nidaamka oo dhalin kara tixraaca wareegga gudaha.SignalMarka hore, isticmaal moduleka cabbirka si aad u ururiso danabka iyo hadda ee barta rarka, xisaabi awoodda firfircoon ee degdegga ah iyo falcelinta ee set-ga koronto-dhaliyaha, ka dibna u gudub shaandhada hoose ee LPF si aad u hesho celceliska awoodda u dhiganta;Haddii loo maleeyo in inta jeer ee la qiimeeyay uu soconayo, koronto-dhaliye-ku-soo-saarka awoodda firfircoon ee P, F, U waa baaxadda korantada ee nidaamka awoodda siday u kala horreeyaan.Inta jeer ee wax soo saarka iyo amarrada baaxadda korantada waxaa laga helaa isku xirka hoos u dhaca, ka dibna korantada tixraaca waxaa lagu soo saaraa isku xirka isku dhafka korantada.Kadibna, danab tixraaceedka waxaa loo isticmaali doonaa sidii danab iyo laba xiriiriye oo hadda jira.

2. Nidaaminta xawaaraha (xakamaynta awoodda-soo noqnoqda ee firfircoon).

Qaadashada awoodda lagu qiimeeyay fN ee koronto-dhaliyaha isku-dhafka ah sida qiimaha tixraaca, marka awoodda firfircoon ee culeyska hoose uu kordho Pred, soo noqnoqda soo-saarka koronto-dhaliyaha ayaa hoos ugu dhacaya qiimaha xasilloon ee cusub ee fref, iyo jiirada qaybta AB waa hagaajinta joogtada ah ee koronto dhaliyaha.Farqiga isku xidhka mp, Δf=fref-fN, ΔP=PN-Pred.Marka dab-dhaliyeyaasha naaftada ay si is barbar socdaan u socdaan, koronto-dhaliye kasta wuxuu si firfircoon u hagaajiyaa inta jeer iyo awooddiisa ilaa dhammaan shuruudaha rarka la buuxiyo.Haddii awoodda unug kasta oo wax soo saara ay la mid tahay, isku-habaynta is-beddelka is-beddelka sidoo kale waa isku mid, awoodda wax-soo-saarkuna waa isku mid;haddii awoodda halbeeggu ka duwan tahay, isku-habaynta toosan ee unugga ee leh halbeeg ka weyn ayaa weyn, unuguna wuxuu si dabiici ah u qaadi doonaa culeysyo badan oo hoose.

3. Nidaaminta korantada (awoodda falcelinta korantada) nidaamka.

Si la mid ah, jiirada qaybta CD-ga waxaa loogu yeeraa fal-celinta awoodda-voltage-ka-hoosaadka kontoroolka koronto-dhaliyaha nq ee koronto-dhaliyaha, kaasoo ka tarjumaysa xiriirka ka dhexeeya kororka awoodda fal-celinta go'an dhalisa iyo weecsanaanta korantada terminaalka, iyo ΔU=Uref-UN, ΔQ=QN-Qred.Marka loo eego jaantuska xannibaadda kontoroolka unugga tamarta kicinta ee koronto-dhaliyaha synchronous, korantada tixraaca waxaa lagu helaa xisaabinta isku xirka cabbirka iyo isku xirka hagaajinta faraqa, ka dibna marka la barbar dhigo koronto-dhaliyaha korantada (xakameeyaha danabku waa kantaroolka PI) , si koronto-dhaliyaha terminalku uu had iyo jeer si degdeg ah u raac amarka danab.
