I-300KW Cummins Generator Programme Reverse Power Protection

Xa ivalve engundoqo ye turbine ijenereyitha ivaliwe ngesizathu esithile, i-injini yomoya isebenza ngaphandle komphunga.Ngeli xesha, i-generator iba yinjini yombane ejika i-rotor ye-turbine.Isantya esiphezulu sokujikeleziswa kweblayidi yeinjini yomoya iya kubangela ilahleko yokuguga komoya, ngakumbi iblade yokuphela kwayo inokubangela ukushisa okugqithisileyo, okukhokelela kwingozi yomonakalo weblade ye-injini yomoya.(Inokuqondwa njengokhuseleko lweblade ye turbine)

Amandla okusebenza :Pop =Krel (P1 +P2)

I-P1: Ilahleko encinci ye-injini yomphunga ekusebenzeni kwamandla angasemva, ngokubanzi i-1% ~ 4% yamandla alinganisiweyo

I-P2: Ilahleko encinci xa ijenereyitha ibaleka kumandla angasemva, ngokuqhelekileyo i-P2∞(1-n) iPgn(n: ukusebenza kakuhle kwejenereyitha, iPgn: amandla alinganiswe yijenereyitha)

I-Krel: i-coefficient yokuthembeka, uluhlu lwe-0.5-0.8.

Ngokubanzi (0.5% ~ 2%) i-generator ireyithiwe amandla, ngokuhambelana nesixhobo sokukhusela esilinganiswe xa i-valve engundoqo ivala ixabiso lamandla.

Ukuthintela ijenereyitha ukuba ikhuphe ngokukhawuleza i-breaker sekethe engundoqo ngaphandle kokuvala zonke iivalvu eziphambili phantsi kwamandla athile asebenzayo, i-turbo generator inokuthi yenzeke iingozi ezikhawulezayo kunye ne-overspeed.Ukunqanda iingozi ezinjalo, i-valve engundoqo ye-injini yomphunga kufuneka ivalwe emva kweentlobo ezithile zokhuseleko (ukulahleka kokhuseleko lwamagnetic, ukhuseleko lwamanyathelo, ukucinywa kwamanzi e-generator, ukusilela kwe-cooler ye-transformer engundoqo, ukukhuselwa kwe-injini yokushisa, njl. njl.).Isetyenziselwa iimpazamo zesekethe ezingezizo ezimfutshane.Emva kokuba i-generator reverse relay yamandla isebenze, uqhagamshelwano oluncedisayo oludityaniswe nevalve engundoqo evaliweyo luya kwenza "kunye" umnyango, kwaye inkqubo yokukhusela umbane wokubuyisela iya kwenziwa emva kwexesha elifutshane, kwaye zonke izitofu ziya kwenzeka emva kokusebenza.

I-valve engundoqo yoqhagamshelwano oluncedisayo, vula i-outlet yokukhusela emva kokuba i-valve enkulu ivaliwe, qalisa uhambo lweprogram yeyunithi emva kokulibaziseka okufutshane.

Amandla esenzo: ngokufanayo nexabiso lesenzo sokubuyisela umva ukhuseleko lwamandla.

Imodi yokuphuma: ukulibaziseka kwe-1.0-1.5s yokusebenza, konke kumisa.

Ukhuseleko lwamandla okubuyisela umva (uhambo lombane)

Ukubuyisela umva ukukhuselwa kwamandla luhlobo lokukhusela i-generator relay, esetyenziselwa ukukhusela i-turbine generator ekusebenzeni okungaqhelekanga xa amandla asebenzayo eguqulwa.

Umgaqo olula wokhuselo lwamandla okubuyisela umva kukwakha isekethe yokulinganisa i-AC yokuhanjiswa kombane ngokomgaqo wexabiso lothelekiso, kunye nesekethe yombane we-AC yamkela indlela yesambuku kunye noqhagamshelo lomahluko, ukuze ufumane umbane wokuthelekisa ezimbini: Ivektha yamandla ombane asisixa i-A1 kunye nevektha yombane umahluko i-A2.Xa i-generator isebenza ngokuqhelekileyo, i-A2.Xa i-valve ye-turbine ye-steam ivalwe ngokukhawuleza, amandla asebenzayo ejeneretha athatyathwa yinkqubo kwaye isenzo sikhulu kunomlinganiselo wokuqhawula.Xa i-A2> i-A1, i-relay action, emva kokulibaziseka okuthile, i-generator cut.Ukhuseleko lwamandla okubuyisela umva lukwakhona kwizinto zokuqalisa uhambo.

I-Dingbo inoluhlu lwasendle lweejenereyitha zedizili: Volvo / Weichai/ Shangcai / Ricardo/Perkins njalo njalo, ukuba ufuna i-pls qhagamshelana nathi
