300KW Cummins Generator Program Reverse Power Protection

Lapho i-valve eyinhloko ye-turbine ijeneretha ivaliwe ngesizathu esithile, i-turbine isebenza ngaphandle kwesitimu.Kuleli qophelo, i-generator iba injini kagesi ephendulela i-rotor ye-turbine.Ukuzungezisa isivinini esikhulu se-turbine blade kuzodala ukulahleka kokugqokwa komoya, ikakhulukazi i-blade yokugcina ingase ibangele ukushisa ngokweqile, okuholela engozini yokulimala kwe-turbine rotor.(Kungaqondwa njengokuvikelwa kwe-turbine blade)

Amandla okusebenza :Pop =Krel (P1 +P2)

I-P1: Ukulahlekelwa okuncane kwe-steam turbine ekusebenzeni kwamandla ahlehlayo, ngokuvamile i-1% ~ 4% yamandla alinganiselwe

I-P2: Ukulahlekelwa okuncane uma ijeneretha isebenza ngamandla ahlehlayo, ngokuvamile i-P2∞(1-n)Pgn(n: ukusebenza kahle kwejeneretha, i-Pgn: amandla alinganiselwe e-generator)

I-Krel: I-coefficient yokuthembeka, ububanzi 0.5-0.8.

Ngokuvamile (0.5%~2%) amandla ejeneretha alinganiselwe, ngokuya ngedivayisi yokuvikela elinganiswa lapho i-valve eyinhloko ivala inani lamandla.

Ukuze uvimbele ijeneretha ukuthi inganqamuki ngokuzumayo i-breaker circuit eyinhloko ngaphandle kokuvala wonke ama-valve amakhulu ngaphansi kwamandla athile asebenzayo, i-turbo generator ingase yenzeke izingozi ezisheshayo nezejubane.Ukuze ugweme izingozi ezinjalo, i-valve eyinhloko ye-steam turbine kufanele ivalwe ngemva kwezinhlobo ezithile zokuvikela (ukulahlekelwa ukuvikela kazibuthe, ukuvikelwa ngaphandle kwesinyathelo, ukunqanyulwa kwamanzi e-generator, ukwehluleka kwe-cooler ye-transformer enkulu, ukuvikelwa kwenjini yokushisa, njll.).Isetshenziselwa amaphutha okujikeleza okungewona amafushane.Ngemuva kokuthi kusetshenziswe ukudluliselwa kwamandla okuhlanekezela i-generator, ukuthintana okuyisizayo okuxhunywe nesivalo esikhulu se-valve kuzokwakha umnyango othi "futhi", futhi uhlelo lokuvikela amandla ahlehlayo luzokwakhiwa ngemva komkhawulo wesikhathi esifushane, futhi konke ukuma kuzokwenzeka ngemva kokusebenza.

I-valve eyinhloko yokuxhumana nomsizi, vula indawo yokuvikela ngemva kokuba i-valve eyinhloko ivaliwe, qala uhambo lohlelo lweyunithi ngemva kokubambezeleka isikhashana.

Amandla esenzo: afanayo nenani lesenzo sokuvikela amandla okuhlehla.

Imodi yokuphuma: ukubambezeleka kokusebenza okungu-1.0-1.5s, konke kuma.

Ukuze uvimbele ijeneretha ukuthi inganqamuki ngokuzumayo i-breaker circuit eyinhloko ngaphandle kokuvala wonke ama-valve amakhulu ngaphansi kwamandla athile asebenzayo, i-turbo generator ingase yenzeke izingozi ezisheshayo nezejubane.Ukuze ugweme izingozi ezinjalo, i-valve eyinhloko ye-steam turbine kufanele ivalwe ngemva kwezinhlobo ezithile zokuvikela (ukulahlekelwa ukuvikela kazibuthe, ukuvikelwa ngaphandle kwesinyathelo, ukunqanyulwa kwamanzi e-generator, ukwehluleka kwe-cooler ye-transformer enkulu, ukuvikelwa kwenjini yokushisa, njll.).Isetshenziselwa amaphutha okujikeleza okungewona amafushane.Ngemuva kokuthi kusetshenziswe ukudluliselwa kwamandla okuhlanekezela i-generator, ukuthintana okuyisizayo okuxhunywe nesivalo esikhulu se-valve kuzokwakha umnyango othi "futhi", futhi uhlelo lokuvikela amandla ahlehlayo luzokwakhiwa ngemva komkhawulo wesikhathi esifushane, futhi konke ukuma kuzokwenzeka ngemva kokusebenza.

Isivikelo samandla esihlanekezela ugesi (uhambo lukagesi)

Ukuvikelwa kwamandla okubuyela emuva kuwuhlobo lokuvikela i-generator relay, esetshenziselwa ukuvikela ijeneretha yomshini womoya ekusebenzeni okungavamile lapho amandla asebenzayo ehlehliswa.

Umgomo olula wokuvikela amandla okubuyela emuva uwukwakha isifunda sokulinganisa i-AC yesidluliseli sesiqondiso samandla ngokuvumelana nesimiso senani lokuqhathanisa, futhi isifunda sokwakha i-voltage ye-AC sithatha indlela yokuxhuma isamba nomehluko, ukuze uthole ugesi wokuqhathanisa okubili: I-sum voltage vector A1 kanye nomehluko we-voltage vector A2.Uma i-generator isebenza ngokujwayelekile, i-A2.Lapho i-valve ye-turbine ye-steam ivalwa ngokuzumayo, amandla asebenzayo we-generator amuncwa uhlelo futhi isenzo sikhulu kunenani lokubhuleka.Lapho i-A2> A1, isenzo sokudlulisa, ngemuva kokulibaziseka okuthile, ukusika kwejeneretha.Ukuvikelwa kwamandla okubuyela emuva kuyatholakala nasezintweni zokuqalisa uhambo.

I-Dingbo inohlu olusendle lwamajeneretha edizili:Volvo / Weichai/ Shangcai /Ricardo/Perkins nokunye, uma udinga pls xhumana nathi
