Abstract: Amasethi ejeneretha kagesi aphansi okwamanje ayinketho yomthombo wamandla ezimo eziphuthumayo kubasebenzisi abaningi, futhi le modeli ivamise ukubhekisa kumasethi ejeneretha kadizili angu-230V/400V asetshenziswa kakhulu emakethe.Nokho, kwezinye izindawo, ngenxa yebanga eliphakathi kwegumbi lokuphehla udizili nezinsiza zikagesi, ukwehla kwamandla kagesi kungase kwenzeke, okubangele ukungakwazi ukusebenzisa ugesi ngendlela evamile, futhi ezimweni ezimbi kakhulu, kushiswe ngisho nezinto zikagesi.Ngakho-ke, kubasebenzisi asebevele bethenge amasethi ejeneretha edizili enengcindezi ephansi, ukuthatha izinyathelo zokuthuthukisa kusuka kungcindezi ephansi kuya kokucindezela okuphezulu kuba yinketho engcono kakhulu, ukuze bangalahli isethi yejeneretha yokucindezela okuphansi futhi kubangele ukulahlekelwa okukhulu kwezomnotho.
1. Ukuqhathaniswa kwezinzuzo kanye nokubi kwengcindezi ephezulu nephansi
1. Izinzuzo zamasethi ejeneretha anamandla kagesi aphezulu:
(1) Amandla we-generator angandiswa, futhi amandla aphezulu wesethi ye-generator high-voltage angafinyelela izinkulungwane ezimbalwa, noma ngisho namashumi ezinkulungwane zama-kilowatts.Lokhu kungenxa yokuthi, lapho ukhipha amandla afanayo, i-current of high-voltage generator ingaba yincane kakhulu kunaleyo ye-low-voltage generator.Ngakho-ke i-high-voltage generator windings ingasebenzisa amadayamitha ocingo amancane.Ngenxa yalokho, ukulahlekelwa kwe-stator yethusi yama-generator aphezulu-voltage nakho kuzoba kuncane kunama-generator aphansi.Kumajeneretha anamandla amakhulu, lapho usebenzisa amandla aphansi-voltage, i-slot enkulu ye-stator iyadingeka ngenxa yesidingo sezintambo ezinkulu, okuholela kububanzi obukhulu be-stator core kanye nomthamo omkhulu we-generator yonke;
(2) Kumajeneretha amakhulu wamandla, amajeneretha anamandla amakhulu asebenzisa amandla amancane kanye nemishini yokusabalalisa kunamajeneretha anamandla aphansi, futhi abe nokulahlekelwa kwelayini ephansi, okungagcina inani elithile lokusetshenziswa kwamandla.Ikakhulukazi kumajeneretha angu-10KV aphezulu, angasebenzisa ngokuqondile ugesi wegridi, okuzonciphisa ukutshalwa kwezimali kumishini yamandla, kube lula ukusetshenziswa, futhi kunciphise izinga lokuhluleka.
2. Ukungalungi kwamasethi ejeneretha ane-voltage ephezulu
(1) Izindleko zama-winding ejeneretha ziphezulu uma kuqhathaniswa, futhi izindleko zezinto ezihambisanayo zokuhlanganisa nazo zizokhuphuka ngokufanele;
(2) Izidingo zendawo yokusetshenziswa kwamajeneretha ziphakeme kakhulu kunalezo zamajeneretha anamandla aphansi;
2. Indlela yokuthuthukisa yamasethi ejeneretha
Ezindaweni ezidinga ukunikezwa kwamandla kagesi aphezulu, ngaphezu kokwabelwa amasethi ejeneretha anamandla kagesi aphezulu, amasethi ajwayelekile e-voltage generator anama-step-up transformer angasetshenziswa.
1. Izinzuzo Zesikimu samandla kagesi aphansi ukuya ku-High Voltage Scheme
(1) Kunezidingo ezimbili noma ngaphezulu ezahlukene zamandla kagesi endaweni yokwakha, noma amandla kagesi esethi yejeneretha kudingeka ashintshwe;
(2) (Umsebenzi wokuhlukanisa ukuguqulwa kwe-Isolation) Isiphetho se-voltage ephezulu siyi-engeli transformer, futhi isistimu yocingo yezigaba ezintathu ayinawo umugqa onguziro.Ngaphandle komugqa onguziro, akukho ukudluliswa komugqa onguziro;Hlukanisa ama-harmonics akhiqizwa imithwalo engeyona imigqa ohlangothini lwamandla kagesi aphezulu ukusuka ohlangothini lwe-voltage ephansi, okwenza uhlangothi lwe-voltage ephansi luhlanzeke futhi lungaphazamisi ukusebenza kwesilawuli se-automatic voltage (AVR) ngaphakathi kwesethi yejeneretha, kanye nokuxazulula izinkinga ezihlukahlukene ezibangelwa ukudluliswa komugqa we-zero;
(3) Umsebenzi wokubhafa we-Great Inertia uwusizo kakhulu ekuqaliseni amamotho amakhulu.Ama-transformer amakhulu amakhulu aqukethe inani elikhulu lezinto zethusi, kanti ingqikithi kazibuthe enkulu idlala indima yokubhafa, inciphisa umthelela kujeneretha futhi ithuthukise ukwehla kwe-voltage ngaleso sikhathi.
2. Ububi be-Parallel Connection Scheme yamayunithi akhiqiza amandla aphansi kagesi
Kusethi yejeneretha engu-380-415Vac, uma amasethi amaningi ejeneretha exhunywe ngokuhambisana ohlangothini lwe-low-voltage bese ekhuliswa i-transformer ekhuphukayo;Umkhawulo ophezulu onconywayo ngu-7500 kVA, 6000 kW.Uma weqa umkhawulo ophezulu, kufanele kubhekwe lezi zinto ezilandelayo:-
Umthamo webha eseceleni ye-voltage ephansi kufanele usondele ku-10kA, kucatshangelwa ikhono lebhasi lokukwazi ukumelana namaza angalungile kanye nokuphathwa kokushisa ngaphakathi kweswiwi ye-low-voltage (ukukhuphuka kwezinga lokushisa kwesikrini sokushintshwa kwe-voltage ephansi);
• Umthamo wokukhubeka wamaswishi ane-voltage ephansi (aze akwazi ukumelana namaza angalungile), afika ku-65kA kanye no-100kA;
• Kuyadingeka ukubala ukuthi ukufakwa kwezintambo ze-ampere ezicishe zibe ngu-10000, amaswishi ane-voltage ephansi, kanye nezindleko ohlangothini lwe-low-voltage zinengqondo yini;
3. Icala lokuvuselela
1. Ukwakheka kwemishini kanye nemingcele
Umsebenzisi: Iphrojekthi e-Macau
● Gcina amandla okunikezwa kwamandla: UPS+6000kVA generator
Isamba somthamo wezimo eziphuthumayo: 4500kVA, 3600kW
Isistimu ye-voltage: I-voltage ephezulu 11kV, 50Hz kanye ne-voltage ephansi 415 Vac50Hz
Amandla: 4 amamodeli we-KTA50-GS8/1200kW amasethi ejeneretha
Ukusebenza kwesethi ye-generator: 3 main kanye nesipele esingu-1, esi-1 sibekelwe ukulungiswa.Isethi ngayinye yejeneretha ingaxhunywa kugridi yamandla ukuze isetshenziswe
Isethi ye-generator voltage: 415Vac/isigaba sesithathu/50 imijikelezo
● Isikrini sokushintsha i-voltage ephansi sesethi yejeneretha:
I-5000A busbar/80kA1 imizuzwana/izigaba ezintathu zezintambo ezine/imijikelezo engu-50
Ibha yebhasi engu-5000A ihlukaniswe izigaba A no-B
Isigaba A sebha yebhasi sixhunywe kumasethi amabili ejeneretha, eyodwa namabili
Isigaba B sebha yebhasi sixhunywe kumasethi amabili ejeneretha, u-3 no-4
Ukufakwa kweswishi ye-5000A4 ye-pole interconnection yezigaba zebhasi A no-B
○ 4 × 2500A iswishi yomoya → exhunywe kumasethi angu-4 akhiqiza ugesi
Iswishi yomoya engu-3 × 3200A → ixhunywe kuma-transformer akhuphukayo angu-3 (uhlangothi olunogesi ophansi)
● Ama-transformer akhuphukayo: 3 amasethi angu-2000kVA11kV/0.415kV
● Isikrini sokushintsha amandla kagesi aphezulu se-transformer: switch vacuum, 15kV600A → exhunywe kuma-step-up transformer angu-3 (uhlangothi lwe-voltage ephezulu)
2. Ukuhlaziya uhlelo
(1) Amayunithi amane ejeneretha e-P1500 axhunywe kugridi ukuze asetshenziswe, kusetshenziswa amayunithi ejeneretha angu-3+1 ngokuhambisana.Kungakhathaliseki ukuthi iyiphi iyunithi edinga ukulungiswa, ayithinti ukunikezwa kwamandla okuphuthumayo;
(2) Uma kwenzeka ukucima kukagesi, amasethi amajeneretha amane azoqala ngesikhathi esisodwa futhi axhume amaswishi amane angu-2500A ane-voltage ephansi kanye namaswishi amathathu angu-200A low-voltage ohlangothini lwe-low-voltage, enza zibuthe isiguquli esikhuphukayo futhi avale ezintathu ezingu-600A phezulu. -ukushintshwa kwe-voltage ukunikeza amandla ezifundeni ezihlukahlukene;
(3) Ukwahlukanisa ngakunye akudingi izikrini zokushintsha okuzenzakalelayo ze-ATS noma amakamelo okukhiqiza azimele, ukonga izindleko eziningi kanye nezinsiza zomhlaba ezibalulekile;Ukuxazulula ngokungaqondile izinkinga zokugcina izinto ezivutha umlilo, imfucumfucu yentuthu, nomsindo obangelwa igumbi lokuphehla ugesi;
(4) Ekuhlolweni kwansuku zonke kwamasethi ejeneretha, umyalo wokuqala ukhishwa kusethi eyodwa noma amaningi ejeneretha aqokiwe ngokulingisa iphutha lamapayipi amakhulu, kodwa amaswishi amane angu-2500A ane-low-voltage kanye namaswishi amathathu we-3200A low-voltage awavali;Futhi amaswishi amathathu e-6000A high-voltage athole uhlelo lokuhlola futhi akhansela isixhumi esiphakathi ukuze kuvalwe.Ibha yebhasi engu-5000A ivuliwe, futhi isethi ngayinye yejeneretha yavunyelaniswa nebha yebhasi.Ngemva kokuhlolwa kokuvumelanisa, inkinobho ye-2500A low-voltage yavalwa;Ngemva kokuvala, isethi ye-generator ibhekana nokuhlolwa komthwalo ogcwele.Ngemva kokuba ukuhlola sekuqediwe, isethi yejeneretha iqala isusa ingcindezi engalungile kanye nohambo lokuqedela ukuhlola (uhambo lokuqala lwe-2500A low-voltage switch -3200A low-voltage switch -600A high-voltage switch);
(5) Lapho isikhungo sokuphakelwa kukagesi simemezela isidingo sokucisha kukagesi, isethi yokuphehla ugesi inganqanyulwa mathupha ekuphakeleni kukagesi ohamba phambili ngemva kokulayishwa ngokuvumelana no-(4), ukuze isethi yejeneretha ikwazi ukuvuleka;Kuze kube yilapho amandla amakhulu ebuyiselwa, isethi ye-generator ivumelanisa namandla amakhulu ngaphansi komthwalo.Ngemuva kokuxhumeka kwegridi, isethi yejeneretha iyasuswa futhi iphume, futhi umsebenzisi akawuzwa umthelela wesikhashana wokucisha kukagesi noma ukushintsha kuyo yonke inqubo;
