Indlela yokuphelisa uzibuthe kunye noMsebenzi we-900kw iGenereyitha yeDizili

900kw ijenereyitha yedizili, njenge isethi yejeneretha yamandla aphezulu , unamandla apheleleyo namandla awomeleleyo.Ngexesha elifanayo, njengesethi ye-diesel generator, ineempawu zokusebenza okulula kunye nokugcinwa okufanelekileyo.Wazi kangakanani malunga nendlela yokukhupha uzibuthe kunye nomsebenzi wejenereyitha yedizili engama-900kw?

Ijenereyitha yedizili engama-900kw iyacima.

Ukusebenzisa i-inverter yesimo sokusebenza kwesigaba sesithathu solawulo olupheleleyo lwebhulorho, i-angle yokulawula iguqulwa ukusuka kwimeko yokusebenza yokulungiswa okungaphantsi kwe-90 ° ukuya kwi-angle efanelekileyo enkulu kune-90 °.Ngeli xesha, amandla okuvuselela atshintshiwe kwaye asetyenziswe kwi-excitation winding ngendlela ye-EMF yangasemva., Inkqubo ye-de-excitation apho i-rotor yangoku ibola ngokukhawuleza ukuya kwi-zero ibizwa ngokuba yi-inverter de-excitation.Le ndlela de-excitation ngokukhawuleza ukondla umva yokugcina amandla rotor ukuya kwicala AC unikezelo lwamandla kwisigaba ezithathu ibhulorho epheleleyo-ulawulo, kwaye ayifuni resistors ukukhupha okanye arc zokucima iigridi.Yindlela elula nesebenzayo yokuphelisa imincili.Ngenxa yokuba akukho mnxibelelwano, akukho arc, kwaye akukho xabiso likhulu lobushushu lenziwayo, i-demagnetization inokuthenjwa.I-EMF enkulu ngasemva, isantya se-demagnetization sikhawuleza.I-EMF yangasemva eveliswe ngexesha lokuguqulwa kwebhulorho yolawulo olupheleleyo lwesigaba sesithathu ilingana ngokuthe ngqo nombane wecala lombane le-AC, ngoko ke ixabiso le-EMF elingasemva lilinganiselwe kwinqanaba elithile.Ngexesha elifanayo, ubuninzi bolawulo olukhulu (okanye i-angle inverter encinci i-angle min) imiselwe ukukhusela "i-inverter subversion".Ukunciphisa) kwakhona kunciphisa i-EMF yangasemva ukuya kwinqanaba elithile.Ke ngoko, i-demagnetization ye-inverter enye ilinganiselwe ngamandla ombane we-AC.Ngexesha le-inverter demagnetization, i-excitation yangoku iyancipha ngokulandelelana, kodwa ixabiso elisetyenzisiweyo le-EMF ngexesha le-inverter demagnetization lincinci kune-arc yokucima igridi ye-demagnetization indlela, ngoko ke i-attenuates yangoku Isantya sincinci, ixesha lokukhupha i-demagnetization lide kakhulu, kodwa i-overvoltage multiple nayo iphantsi kakhulu.

I-900kw ijenereyitha yedizili engahambelani ne-demagnetization.

Xa inkqubo yokuvuselela ivaliwe ngokuqhelekileyo, umlawuli uya kwenza ngokuzenzekelayo i-magnetize nge-inverter;ukuba ivalwe ngengozi, iswitshi ye-demagnetization iyakutsibela ukuhambisa amandla omhlaba wemagnethi ukuya kwisixhasi esithatha amandla ukuze singabizibuthe.Xa ijenereyitha ikwimeko yokusebenza engaqhelekanga njengokutyibilika, amandla ombane aphezulu kakhulu aya kuveliswa kwisekethe yerotor.Ngeli xesha, i-rotor overvoltage monitoring unit unit A61 efakwe kwi-rotor circuit iya kubona i-rotor phambili i-overvoltage signal kwaye ngoko nangoko Qalisa i-V62 thyristor element, idibanise i-energy dissipation resistor unit FR kwi-circuit ye-rotor, kwaye isuse amandla ombane ogqithisiweyo. ukufunxwa kwamandla okumelana nokuchithwa kwamandla;kunye ne-reverse overvoltage signal ye-rotor circuit idlula ngokuthe ngqo kwi-tube ye-V61 yesibini I-resistant dissipation resistor idibaniswe ukuze ithathe amandla ukuze kuqinisekiswe ukuba i-rotor ye-generator ayiyi kuvula isiphaluka, ukwenzela ukuba ikhusele ngokuthembekileyo i-rotor insulation kumonakalo.Ngenxa yobukho bolu hlobo lokhuseleko, i-rotor winding iya kuvelisa i-magnetic field echaseneyo, enokunciphisa i-reverse magnetic field eyenziwa ngokulandelelana okungahambi kakuhle kwe-stator, ukwenzela ukukhusela umphezulu we-rotor kunye neringi yokugada i-rotor ukusuka. ukutshisa ngaphandle.

Indima ye-900kw generator diesel magnetoresistance.

Ukuvuthuza kovuyo lwe-a 900kw ijenereyitha yedizili yikhoyili ene-inductance enkulu.Ngaphantsi kweemeko eziqhelekileyo, i-excitation yangoku ivelisa indawo enamandla yamagnetic kwi-rotor generator.Xa ijenereyitha yedizili engama-900kw isilela ngaphakathi, kuyafuneka ukuba ukhawuleze unqumle i-excitation current kwaye ususe imagnethi ye-900kw yejenereyitha yedizili ukunqanda ukwanda kwengozi.Nangona kunjalo, kunzima kakhulu ukusebenzisa iswitshi ukunqumla ngokuthe ngqo umsinga kwisekethe enjalo kunye ne-inductance enkulu.Ngenxa yokuba ukunqumla ngokuthe ngqo i-excitation current kuya kuvelisa amandla ombane aphezulu kuzo zombini iziphelo zomoya wokuvuselela, ezinokutshisa abafowunelwa bokutshintsha.Ke ngoko, ngaphambi kokuba unqumle i-excitation circuit, qala uqhagamshele ukuchasana kwe-de-excitation kuzo zozibini iziphelo zerotor ngokunxuseneyo, ukuze xa i-excitation circuit inqunyulwe, ukuchasana kwe-de-excitation kunokukhawuleza ukufunxa amandla emagnethi e-excitation winding. , nciphisa isantya sokutshintsha kwe-rotor yangoku, kunye nokunciphisa i-rotor self I-electromotive force eyenziwe idlala injongo yokunciphisa i-rotor overvoltage kunye ne-demagnetization.

Ukuxhatshazwa kwe-de-excitation ayikho xa i-900kw generator ye-diesel ihambelana okanye i-de-arranged, kodwa xa i-generator ye-diesel ye-900kw isetyenzisiweyo, i-resistor de-excitation ifakwe kwaye ibekwe kuzo zombini iziphelo zekhoyili ye-rotor. sisitshixo esisetyenziselwa ukunciphisa ngokukhawuleza okwangoku kwisiphaluka sokuvuselela.Ngaphambi kokuba uqale ukwakha i-voltage, faka i-de-excitation switch.Kwimeko yokuvalwa kwejenereyitha yedizili engama-900kw okanye ngengozi, hambisa iswitshi yokucima ukuvuselela ukucima umsinga ovuselelayo ukuze kuphunyezwe injongo yokunciphisa ngokukhawuleza umbane wejenereyitha yedizili engama-900kw.

isiphumo:

(1) Kukunqumla ngokukhawuleza i-900kw yejenereyitha yokuvuselela ijenereyitha kunye nendlela yokuvuselela amandla.

(2) Ukucima ngokukhawuleza imagnethi ngaphakathi kwe-900kw generator diesel.
