Ziziphi izinto eziluncedo zoKhuseleko lweeSeti zeGenereyitha yeDizili ethuleyo

Silent genset inokunciphisa ingxolo kwaye ithandwa kakhulu kwiindawo zokuhlala, ezibhedlele nakwezinye iindawo.Kwiminyaka yakutshanje, imarike yeejenereyitha zedizili ezithuleyo iye yafuneka ngakumbi nangakumbi.Makhe sijonge kwiijenereyitha zedizili ezithuleyo ngezantsi.Iinzuzo ezilishumi zokhuseleko.

1. Ijenereyitha ye-diesel ethuleyo yokulahlekelwa kwe-excitation yokukhusela.

Ukukhuselwa kokulahlekelwa kwe-excitation kusetyenziswa njengelahleko-ye-excitation yokukhusela impazamo xa i-excitation current ye-generator ihla ngokungaqhelekanga okanye iphele ngokupheleleyo.Iqulunqwe ziikhrayitheriya ezinje nge-excitation low voltage Ufd(P), i-voltage ephantsi yenkqubo, i-static impedance, uqhawulo lwe-TV oluthi ixabiso lokumisela litshintsha ngokuzenzekelayo ngamandla asebenzayo, asebenza ngokusayina kunye nokucima uvuyo ngokulandelelanayo.Zombini i-excitation low voltage Ufd (P) ikhrayitheriya kunye nekhrayitheriya yozinzo lwe-static inxulumene nomda wozinzo omileyo, onokubona ukuba i-generator ilahlekelwa ukuzinza kwayo okumileyo ngenxa yokulahleka kovuselelo.Uzinzo oluzinzileyo lwekhrayitheriya lusebenza kumda wozinzo olumileyo emva kokulahleka kwemagnethi.

2. Thulisa ijenereyitha yedizili ukhuseleko olugqithisileyo.

Ukukhuselwa kwe-overexcitation lukhuselo olubonisa ukusebenza ngokugqithisileyo koxinaniso lwemagnethi yombindi wentsimbi obangelwa kukucutha amaza ombane wejenereyitha okanye amandla ombane agqithisileyo.Ukukhuselwa kwe-overexcitation kuhlukaniswe kwiindawo eziphezulu kunye nezisezantsi.Ummiselo ophantsi uthumela umqondiso emva kokulibaziseka okusisigxina kwe-5s kunye nokunciphisa i-voltage excitation (umsebenzi wokunciphisa i-voltage ye-excitation kunye ne-excitation current ayisetyenziswanga okwethutyana), kwaye i-high setting isebenza kwi-de-loading emva komda wexesha eliphambeneyo.I-Demagnetization.Umda ophezulu wokulibaziseka kwexesha le-inverse yimizuzwana emi-5, kwaye umda ophantsi yimizuzwana engama-200.

3. Ijenereyitha ye-dizeli ethuleyo yokukhusela i-stator yomhlaba.

I-generator stator grounding protection isetyenziswe njenge-generator stator yesigaba esisodwa sokukhusela impazamo.Iqulathe amacandelo amabini: inxalenye yombane wolandelelwano olusisiseko onguziro kunye nombane wesithathu we-harmonic.I-voltage esisiseko yokulandelelana kwe-zero ikhusela i-stator yesigaba esinye somoya kwindawo ye-95% ukusuka ekupheleni komatshini ukuya kumsila womatshini.Isiphoso somhlaba siqulunqwe ngokubonakalisa umgaqo we-voltage ye-zero-sequence ekupheleni kwe-generator, esebenza kwi-demagnetization emva komda wexesha le-t1 (3s);i-voltage yesithathu ye-harmonic ikhusela i-single-phase-grounding fault of the stator winding from the generator tail to 30% of the end of generator.Indawo engathathi hlangothi yejeneretha kunye nomgaqo wesithathu-harmonic ekupheleni kwejenereyitha yenziwe, kwaye isebenze kwisignali emva kwexesha le-t2 (5s).Ezi zimbini zenza i-100% yokukhusela i-stator grounding.Ukhuseleko luxhotyiswe nge-PT yokuvala uqhagamshelo.

4. I-dizeli ethuleyo yokukhusela i-stator yokujika yokukhusela.

Ukhuseleko luqulunqwe ngumbane wolandelelwano lwe-longitudinal zero kunye nekhrayitheriya yolandelelwano olubi lwecandelo lempazamo.Amanyathelo okuthintela ukunqanyulwa kwe-PT amiselwe njengokhuseleko oluphambili lokujika kwangaphakathi kwejeneretha kunye nesigaba esifutshane sesiphaluka kunye ne-welding evulekileyo ye-stator winding.Ikhrayitheriya yecala lolandelelwano olubi lwecandelo lesiphoso liyagqithiswa Ukubona amandla alandelelanayo angalunganga aphuma kwijenereyitha ukuqonda ikhrayitheriya yomthamo we-longitudinal zero-ulandelelwano lwevoltage iphunyezwa ngokubona i-longitudinal 3UO iphumayo nge-3PT evulekileyo ye-delta evuthuzayo enendawo yokungathathi hlangothi iqonde ngqo. iqhagamshelwe kwindawo engathathi hlangothi yejenereyitha kodwa ayisekelwanga.Isenzo sokukhusela sikwisigxina.

5. Ijeneretha ye-diesel ethuleyo ngaphandle kwenyathelo lokukhusela.

Ukukhuselwa kusebenzisa i-impedance element emithathu ukuze kubonwe inani leepali ze-sliding kunye nokumisela indawo yeziko le-oscillation ngokutshintshwa kwendlela yokuthintela.Kwimeko yesiphambeko sesiphaluka esifutshane, i-oscillation yenkqubo, ukuchithwa kwesekethe ye-voltage, njl., ukukhuselwa akuyi kusebenza kakubi.Ukhuseleko lusebenza ngokubanzi kumqondiso;xa isikhungo se-oscillation singaphakathi kweqela le-generator-transformer, isigaba sokukhusela ndiqala kwaye ndithumela umyalelo wohambo nge-t1 (0.5s), esebenza kwi-de-excitation;xa isikhungo se-oscillation singaphandle kweqela le-generator-transformer, ukukhuselwa Ukuqala kwecandelo II kubonakaliswe kwi-t2 (2s).Isixhobo sokukhusela sixhotyiswe ngesixhobo sokuthintela ngoku ukuze kuqinisekiswe ukuba i-current ayidluli kwi-rated out-of-step breaking current of the circuit breaker xa i-circuit breaker ivaliwe.

6. Ukukhuselwa okunyukayo okuphantsi kweejenereyitha zedizili ezithe cwaka.

Ukhuseleko lokuqokelelwa kweefrikhwensi ezisezantsi lusabela kwisiphumo esongezelekayo sokuncitshiswa kwamaza enkqubo kwi-injini yomphunga.Ukhuselo lubandakanya i-relay frequency ebuthathaka kunye nekhawuntara, kwaye ivalwe luqhagamshelwano oluncedisayo lwe-breaker circuit outlet (oko kukuthi, ukhuseleko oluphantsi lwe-frequency yokuqokelela nayo iyaphuma xa i-generator iphuma ekusebenzeni), kunye ne-cumulative system frequency iphantsi. i-frequency isethwe kwi-47.5 Hz, xa ixesha eliqokelelweyo lifikelela kwixabiso elimiselweyo lemizuzwana ye-3000, isignali iya kuthunyelwa emva kokulibaziseka kwemizuzwana ye-30.Isixhobo sinokujongwa ngexesha lokwenyani ngexesha lokusebenza: ixabiso elimiselweyo, i-frequency f kunye ne-cumulative time display.

7. Thula diesel generator excitation ukhuselo overload.

Ukukhuselwa kwe-excitation circuit overload isetyenziselwa ukukhusela i-rotor excitation circuit kwi-overcurrent okanye i-overload.Idityaniswe kwisigaba sesithathu kwaye iqulethwe ngamacandelo amabini: ixesha eliqinisekileyo kunye nomda wexesha elichaseneyo.Umbane osebenzayo wenxalenye yexesha eliqinisekileyo usekwe ngokwemeko yokuba inokubuyiselwa ngokuthembekileyo phantsi komgangatho obekiweyo wokusebenza okuqhelekileyo.Emva kwexesha elilinganiselwe le-t1 (5s), lisebenza kwisignali kwaye linciphisa ukutshatyalaliswa kwangoku (umsebenzi wokunciphisa umbane wokuvuselela awusetyenziswanga);Uphawu lwesenzo senxalenye yexesha eliguquguqukayo ngokwejenereyitha Umthamo womthwalo ogqithisileyo wokuvuthuza okujikajikayo umisiwe, kwaye isenzo sokukhusela sisekususeni amandla kunye nokucima.Umda ophezulu womda wexesha eliguquliweyo yimizuzwana eyi-10.

8. Inqaku elinye lokukhuselwa komhlaba kwi-rotor ye-generator ye-diesel ethuleyo.

I-generator ye-rotor enye indawo yokukhusela isiseko isetyenziselwa ukubonakalisa impazamo yomhlaba omnye wesiphaluka se-rotor generator.Ukhuseleko lwamkela umgaqo wokutshintsha kweping-pong.I-voltages yomhlaba echanekileyo kunye nembi yesekethe ye-rotor isampuliwe, kwaye ukuxhathisa kwe-rotor grounding kubalwa ngexesha langempela ngokusombulula ii-equations ezimbini ezahlukeneyo zomhlaba.Kwaye indawo yokumisa.Ukhuseleko luya kusebenza kwisignali emva kokulibaziseka kwemizuzwana ye-2.

9. Ukukhuselwa komthwalo olinganayo kwiijenereyitha zedizili ezithe cwaka.

Isixhobo sokukhusela siqulunqwe ngamacandelo amabini: ixesha eliqinisekileyo kunye nomda wexesha elichaseneyo.Inxalenye yexesha eliqinisekileyo lisebenza kwisiginali emva komda wexesha lemizuzwana emi-5.Uphawu lwesenzo sexesha eliguquguqukayo lumiselwa ngokwesakhono sejenereyitha yokumelana nomthwalo ogqithisiweyo wangoku, kwaye isenzo sikwi-de-loading.Isixhobo sokukhusela sinokubonakalisa inkqubo yokuqokelela ubushushu be-stator ye-generator.

10. Ulandelelwano olungalunganga lokhuseleko lomthwalo ogqithisiweyo kwiijenereyitha zedizili ezithuleyo.

Isixhobo sokukhusela siqulunqwe ngamacandelo amabini: ixesha eliqinisekileyo kunye nomda wexesha elichaseneyo.Ixesha eliqinisekileyo lomda wentshukumo yangoku imiselwe ngokwexesha elide elivumelekileyo lolandelelwano olubi ixabiso langoku le ijenereyitha kunye nexabiso langoku elithintela ukungalingani kwesihluzo sangoku sokulandelelana okungalunganga phantsi komthwalo omkhulu.Izenzo zesibini kumqondiso.Uphawu lwesenzo sexesha eliphambeneyo luchongwa ngokuhambelana namandla ejeneretha yokumelana nolandelelwano olubi lwangoku, kwaye isenzo sikwi-de-excitation kunye ne-de-excitation.
