Layisha iSpeed ​​​​Speed ​​and Power Factor of Generator Set

Ukunyuka kwesantya somthwalo emva kokuba i-generator ixhunywe kwigridi kufuneka inqunywe ngokuhambelana nomthamo weyunithi, iimeko zokupholisa kunye nokufudumala kunye neemeko zokusebenza zangempela.Ukuba ubushushu be-stator winding kunye ne-stator core ye-generator idlula i-50% yeqondo lokushisa elilinganisiweyo, i-generator inokuthathwa njengento eshushu.Ukuba iqondo lokushisa le-stator winding kunye ne-stator core lingaphantsi kwe-50% yeqondo lokushisa elilinganisiweyo, i-generator ingathathwa njengento eshushu.Isimo esibandayo.Emva kokuba i-turbo generator idibaniswe kwinkqubo yamandla ukusuka kwimeko ebandayo, ngokuqhelekileyo i-stator inokuthwala ngokukhawuleza i-50% ye-current rated current, ize iphakame kwixabiso elilinganisiweyo kwisantya esifanayo kwimizuzu engama-30.Ngokutsho kwedatha efanelekileyo, kuthatha malunga nemizuzu ye-37 kwi-stator yangoku ye-a Iseti yejenereyitha eyi-1MW ukufikelela kwixabiso elilinganisiweyo ukusuka kwi-50%.

Isizathu sokunciphisa isantya sokunyuka komthwalo wejeneretha kukuthintela i-deformation eseleyo ye-rotor windings.Ngenxa yokuba i-rotor ijikeleza ngesantya esiphezulu, amandla amakhulu e-centrifugal acinezela i-rotor windings kwi-slot wedge kunye ne-ferrule ye-rotor core, eyenza into engenakushukunyiswa.kukonke.Emva kokuba i-rotor ishushu, ukwandiswa kwentonga yobhedu ejikelezayo kukhulu kunokwandiswa kwentsimbi yentsimbi kwaye ayikwazi ukuhamba ngokukhululekile.Intonga yobhedu icinezelekile kwaye ikhubazekile.Xa uxinzelelo loxinzelelo ludlula umda we-elastic, i-deformation eseleyo iya kwenzeka.Xa i-generator ivaliwe ukupholisa, i-copper iyancipha ngaphezu kwentsimbi, eya kubangela umonakalo we-insulation, kwaye umzantsi wetanki unzima kakhulu.Esi siganeko siphinda rhoqo xa siqala kwaye siyeke, kwaye i-residual deformation iqokelela ngokuthe ngcembe, enokubangela isiphaluka esifutshane phakathi kokujika okanye impazamo yomhlaba.Ngoko ke, "iMimiselo" ichaza ixesha elifunekayo ukuze i-stator yangoku inyuke ukusuka kwi-50% (ngokwezibalo, xa ukunyuka ngokukhawuleza komthwalo kungadluli i-50% ye-current rated current, i-rotor winding ayiyi kuvelisa i-deformation residual) I-100% yexabiso langoku.Ukongezelela, xa Xa i-generator ikwimeko eshushu okanye engozini, isantya apho umthwalo unokunyuswa emva kokuhlanganiswa kwinkqubo yamandla ayikhawulelwanga.

I-power factor cosΦ ye-generator, eyaziwa ngokuba yi-force rate, yi-cosine ye-angle yesigaba phakathi kwe-voltage ye-stator kunye ne-stator yangoku.Ibonisa ubudlelwane phakathi kwamandla asebenzayo, amandla asebenzayo kunye namandla abonakalayo akhutshwa yijenereyitha.Ubungakanani bayo bubonisa imveliso yejenereyitha yomthwalo osebenzayo kwisixokelelwano.Umthwalo osebenzayo othunyelwa yijenereyitha udla ngokuba yi-inductive.Ngokubanzi, amandla alinganisiweyo we-generator yi-0.8.

Xa amandla ombane we-generator atshintsha ukusuka kwixabiso elilinganisiweyo ukuya kwi-1.0, umphumo olinganisiweyo unokugcinwa.Kodwa ukuze kugcinwe ukusebenza okuzinzile kwejeneretha, umbane wamandla akufanele udlule i-0.95 kwisigaba sokugqibela, ngokuqhelekileyo usebenza kwi-0.85.

Xa amandla ombane angaphantsi kwexabiso elilinganisiweyo, imveliso ye-generator kufuneka icuthwe.Ngenxa yokuba esezantsi into yamandla, kokukhona icandelo elisebenzayo le-stator yangoku, kwaye inamandla impendulo yezixhobo ze-demagnetization.Ngeli xesha, ukuze kugcinwe i-terminal voltage ye-generator ingatshintshi, i-rotor current kufuneka inyuswe, kwaye i-generator stator current nayo Yandiswa ngokunyuka kwamacandelo asebenzayo.Ngeli xesha, ukuba ukuveliswa kwejeneretha kuya kugcinwa rhoqo, i-generator rotor current kunye ne-stator current iya kudlula ixabiso elilinganisiweyo, kwaye ukushisa kwe-rotor kunye nokushisa kwe-stator kuya kudlula ixabiso elivumelekileyo kunye nokugqithisa.Ngoko ke, xa i-generator isebenza, ukuba amandla ombane angaphantsi kwexabiso elilinganisiweyo, kufuneka kuthathelwe ingqalelo ukulungelelanisa umthwalo ukwenzela ukuba i-rotor yangoku ingadluli ixabiso elivumelekileyo.
