Ukusebenza komthwalo weeGenereyitha zeDizili zeVolvo

1. Intshayelelo kwithoni enzulu

Ukucheba okunzulu luhlobo lwendlela yokusebenza apho imveliso yezityalo zamandla iyancitshiswa kwaye iiseti zejenereyitha zigqithise isikali esisisiseko sokucheba ngenxa yomahluko omkhulu wentlambo yentlambo yomthwalo wegridi.Isikali somthwalo wolawulo lwencopho enzulu ludlula ubuninzi obuzinzileyo bomthwalo wokutsha webhoyila yeplanti yamandla (ngokubanzi, ubunzulu bolawulo oluphezulu lommiselo wencopho enzulu yi-60% -70% BMCR).Okwangoku, amandla okushisa amalahle abonisa iimpawu zokunyuka kwenani leeyunithi ezithatha inxaxheba ekulawuleni umthwalo ophezulu okanye ukulamla, ukunciphisa iiyure zenkonzo kunye nezinga eliphantsi lomthwalo weyunithi.

I-peak-shaving mode ye-coal-fired thermal power unit yomenzi we-generator ngumsebenzi womthwalo oguquguqukayo, kwaye umenzi we-generator uhlengahlengisa ngokunzulu umthwalo ngaphaya kobunzulu bohlengahlengiso jikelele, kwaye umthwalo uguquka ngokukhawuleza.

Kwixesha elidlulileyo, umgaqo-nkqubo wokucwangcisa umthamo omkhulu weyunithi yamandla okushisa amalahle yayisebenza ixesha elide elizinzileyo kunye nomthwalo wesiseko, kwaye ugxininiso lwalukwindlela yokwandisa imo yokupholisa ye-stator ukujija kunye ne-stator core, ukuze kuphuculwe imveliso. amandla kunye neeparamitha zemoto phantsi kwemeko yomthwalo opheleleyo.Nangona kunjalo, ngenxa yotshintsho kwimeko yokusebenza yangaphandle yegridi yamandla, indlela yokusebenza yejeneretha yahluke kakhulu kuleyo yakudala.Ixesha kunye nokuphindaphinda kokulawulwa kwencopho, ukulawulwa koxinzelelo kunye nokusebenza kwesigaba sokungena kwanda kakhulu.Nangona ekuqaleni kokucwangciswa kwejenereyitha, iimpembelelo zeendawo ezahlukeneyo zokusebenza kwijenereyitha zicatshangelwe kwaye amanyathelo ahambelanayo athatyathwa ukuhlangabezana nawo, ngokwenene, ii-turbogenerators ezimbalwa ezinkulu ezisebenza phantsi kwexesha elide kunye nokulawulwa koxinzelelo kubandakanywa nesigaba sokufaka. , kwaye uhlalutyo lwendlela yezi ndlela zokusebenza kwishishini alanelanga.

2. Uhlalutyo oluthelekisayo lwempembelelo yemowudi yokusebenza eqhelekileyo kunye nohlengahlengiso lwencopho yobunzulu kwi-stator kunye ne-rotor windings kunye nombindi wentsimbi wejenereyitha.

E-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd, kukho ii-turbogenerators ezisi-8 ezibaswa ngamalahle kwinkonzo, phakathi kwazo iijenereyitha ezingama-635MW kunye ne-1000MW zonke zibandakanyeka kuhlengahlengiso olunzulu.Ngenxa yeengxaki ezinokwenzeka kuhlengahlengiso olunzulu, ukulungelelaniswa kwejeneretha kunye ne-rotor zihlolwe ngokubanzi ngexesha lokulungiswa okukhulu kunye nokuncinci.Ngethuba lexesha lohlengahlengiso olunzulu, uhlalutyo lwedatha lugxininise kumahluko wokwandiswa kwe-thermal phakathi kwentsimbi yentsimbi kunye nentonga yocingo yokulungelelanisa i-generator kunye ne-rotor.Ukuze uhlalutye iqondo lempembelelo ye-modulation enzulu kwinkqubo yombane, yenza uphando kunye nemilinganiselo yokuchasana.

2.1 Uhlalutyo lweempazamo eziqhelekileyo ze ijenereyitha i-stator kunye ne-rotor kwindlela yokusebenza eqhelekileyo

2.1.1 Isiphelo sestator sikhululekile

Kuhlaziyo lweyunithi ye-1000MW ngo-2014, kwafunyaniswa ukuba iphini lokutyibiliza elimilise okwe-l ekupheleni kwejenereyitha stator lalinxitywe kwiindawo ezintandathu, isibiyeli sikwi-10, 11, 12, 1, 2, 4 kunye ne-5 o. 'iwotshi phakathi stator imincili isibiyeli ekupheleni kunye nekhonkco umsesane inxitywe izidanga ezahlukeneyo, kwaye ukhokelo 11 o phakathi kwesiphelo imincili kunye umsesane inkxaso inxitywe ngomgubo kancinane omthubi.Unyango: coca, jonga, phinda usete isikhonkwane sesilayidi, kwaye ulungise isikhonkwane sesilayidi.Susa intambo yokubopha ekhululekileyo ye-stator ring lead, yongeza ibhloko yomgama kwi-lead lead, kwaye uyibophe ngokuqinileyo nge-φ 5 intambo ye-polyester wave efakwe kwiglue ye-NAZ.

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. esekwe ngo-2006, ngumvelisi wejenereyitha ye-diesel e-China, edibanisa ukuyila, ukubonelela, ukuthunyelwa kunye nokugcinwa kweseti yejeneretha ye-diesel.Imveliso igubungela iCummins, iPerkins, iVolvo, iYuchai, iShangchai, Dutz , Ricardo, MTU, Weichai njl kunye noluhlu lwamandla 20kw-3000kw, kwaye babe ngumzi-mveliso wabo we-OEM kunye neziko lobuchwepheshe.
