Kushanda Nheyo yeOtomatiki Kudzora System yeDiesel Jenareta Set

Parizvino, nekukura kunoramba kuripo kwebhizinesi rebhizinesi, kushandiswa kwesimba kwemazuva ese kwenzvimbo yedata kuri kuratidzawo maitiro ekukura panguva imwe chete.Kamwe kana mains simba kutadza kuitika, imwe dhiziri jenareta haigone kusangana nedata rekuchengetedza simba rinodiwa zvachose, saka rinowanzoda rimwe simba.Mauniti ari kushanda akafanana.Kuti uvandudze kushanda kwehupfumi uye kuvimbika kwehurongwa hwekushanda kwesimba remagetsi, izvi zvinoda kuti iyo system yekudzora logic haingodi kuti unit pachayo iite zvakanaka, asi inodawo kuti unit yega yega itakure zvine musoro mitoro inoshanda uye inoshanda muzasi kwerwizi. system.Izvi zvinodikanwa zvinoratidzwa pamwe chete Muiyo yekumhanyisa regulation system yeiyo prime mover uye voltage regulation system ye synchronous jenareta .

1. Drop control.

Kuti uone kugadzikana kwekushanda kwakafanana kwemaseti ejenareta, droop control inowanzogamuchirwa, kureva, P / f droop control uye Q / V droop control inoshandiswa kuwana yakagadzikana frequency uye voltage.Iyi nzira yekudzora inokanganisa simba rinoshanda rinobuda nechikamu chimwe nechimwe.Kuparadzanisa kutonga nesimba rinoshanda, pasina kudiwa kwekutaurirana uye kubatana pakati pezvikamu, kuwana peer-to-peer kutonga pakati pemayuniti, uye kuve nechokwadi chechiyero chekugovera uye kudiwa uye frequency kugadzikana kwedhiziri generator set parallel system.

Iyo droop control inotora voltage uye ikozvino mbiri-loop control.Ikozvino yemukati loop ine inokurumidza dynamic yekupindura kumhanya, iyo inoshandiswa kugadzirisa simba remhando yejenareta seti.Iyo voltage yekunze loop controller ine inononoka dynamic yekupindura kumhanya, iyo inogona kudzora inobuda voltage yesystem uye kugadzira yemukati loop referensi.Signal.Kutanga, shandisa iyo yekuyera module kuunganidza voltage uye ikozvino yenzvimbo yekuremedza, kuverenga iyo pakarepo inoshanda uye inogadzirisa simba rejenareta seti, uye wozopfuura yakaderera-pass sefa LPF kuti uwane inoenderana avhareji simba;tichifungidzira kuti yakayerwa frequency iri kushanda, iyo jenareta seti inobuda inoshanda simba P, F, U ndiyo frequency uye yakayerwa voltage amplitude yesimba system zvichiteerana.Iyo inobuda frequency uye voltage amplitude mirairo inowanikwa kuburikidza neiyo droop link, uyezve referensi voltage inogadzirwa kuburikidza neiyo voltage synthesis link.Zvadaro, iyo referensi voltage ichashandiswa sevoltage uye ikozvino mbiri mbiri yekubatanidza Controller yekupinda.

2. Speed ​​​​regulation (inoshingaira simba-frequency control) system.

Kutora iyo yakatemerwa simba fN yejenareta inopindirana seyereferensi kukosha, kana simba rinoshanda remutoro wezasi richiwedzera kusvika kuPred, iyo inobuda frequency yeiyo synchronous jenareta inodonha kune yakagadzikana kukosha kwefref, uye kutsetseka kwechikamu AB ndiyo static kugadzirisa kweiyo synchronous jenareta.Musiyano wepakati mp, Δf=fref-fN, ΔP=PN-Pred.Kana dhiziri seti yejenareta iri kushanda zvakafanana, jenareta yega yega inogadzirisa zvine simba frequency uye simba kusvika zvese zvinodikanwa zvasangana.Kana huwandu hwechimwe nechimwe chekugadzira chikwata chakafanana, iyo static kugadzirisa coefficient zvakare yakafanana, uye simba rinobuda rinowanzofanana;kana chiyero cheyuniti chakasiyana, iyo static gadziriso coefficient yeyuniti ine yakakura imwe unit unit yakakura, uye iyo unit inozotakura inotakura mitoro yepasi.

3. Voltage regulation (reactive power-voltage control) system.

Nenzira imwecheteyo, kutsetseka kwechikamu cheCD kunonzi reactive power-voltage droop control coefficient nq ye synchronous generator, iyo inoratidza hukama pakati peiyo reactive simba kuwedzera kweiyo. kugadzira set uye iyo terminal voltage deviation, uye ΔU = Uref-UN, ΔQ = QN-Qred.Zvinoenderana nedhizaini yekudzora dhizaini yeiyo yekukurudzira simba unit yeiyo synchronous jenareta, iyo referensi voltage inowanikwa kuburikidza nekuverenga kweyero yekuyera link uye musiyano wekugadzirisa link, wozoenzaniswa nejenareta terminal voltage (iyo voltage regulator iPI control) , kuitira kuti jenareta terminal voltage nguva dzose Kurumidza kutevera voltage command.

Kana iwe uchida kuziva zvakawanda nezve majenareta edhiziri, ndapota taura neDingbo Power neemail dingbo@dieselgeneratortech.com.
