Esihlokweni sokugcina, sethule isinqumo se-DC AC."impi" yaphela ngokunqoba kwe-AC.ngakho-ke, i-AC yazuza intwasahlobo yokuthuthukiswa kwemakethe futhi yaqala ukuthatha imakethe eyayikade isetshenziswa yi-DC.Ngemva kwale “mpi”, i-DC kanye ne-AC baqhudelana esiteshini sikagesi esiphehlwa ngamanzi e-Adams e-Niagara Falls.
Ngo-1890, i-United States yakha isiteshi sikagesi sase-Niagara Falls Adams.Ukuze kuhlolwe izikimu ezehlukene ze-AC kanye ne-DC, kusungulwe Ikhomishini Yamandla Yase-Niagara kazwelonke neyamazwe ngamazwe.U-Westinghouse no-Ge babambe iqhaza emqhudelwaneni.Ekugcineni, nedumela layo elikhulayo ngemuva kokunqoba kwempi ye-AC / DC kanye namakhono eqembu lososayensi abahle kakhulu abanjengoTesla, kanye nokuhlolwa okuyimpumelelo kokudluliswa kwe-AC eGreat Barrington ngo-1886 kanye nokusebenza ngempumelelo kwe-alternator ku-larffen. isikhungo sikagesi eJalimane, i-Westinghouse ekugcineni iwine inkontileka yokukhiqiza yamajeneretha angu-10 5000P AC hydro.Ngo-1894, i-5000P yokuqala ye-hydro generator yesiteshi sikagesi sase-Niagara Falls Adams yazalwa e-Westinghouse.Ngo-1895, iyunithi yokuqala yaqala ukusebenza.Ekwindla ka-1896, amandla ashintshayo ezigaba ezimbili akhiqizwa ijeneretha yaguqulwa yaba yizigaba ezintathu nge-Scot transformer, yase idluliselwa e-Baffalo 40km kude ngohlelo lokudlulisela lwezigaba ezintathu.
I-hydro generator yesiteshi sikagesi sase-Adams e-Niagara Falls yaklanywa ngu-BG lamme (1884-1924), unjiniyela omkhulu wase-Westinghouse, ngokwelungelo lobunikazi lika-Tesla, kanye nodadewabo u-B. lamme nabo babambe iqhaza ekwakhiweni.Iyunithi iqhutshwa yi-fournellon turbine (umgijimi ophindwe kabili, ngaphandle kweshubhu esalungiswa), futhi ijeneretha iyijeneretha ye-synchronous yezigaba ezimbili eqondile, 5000hp, 2000V, 25Hz, 250r / mln.Ijeneretha inalezi zimpawu ezilandelayo;
(1) Umthamo omkhulu nosayizi omude.Ngaphambi kwalokho, umthamo weyunithi eyodwa ye-hydro generator awuzange udlule i-1000 HPA.Kungashiwo ukuthi i-5000bp hydro generator yesiteshi sikagesi i-Adar hydropower e-Niagara Falls yayingeyona nje ijeneretha enkulu kakhulu yamanzi enomthamo weyunithi eyodwa emhlabeni ngaleso sikhathi, kodwa futhi yayiyisinyathelo sokuqala esibalulekile ekuthuthukisweni kwe-hydro generator kusukela kwencane kuya enkulu. .
(2) Ikhondatha yezikhali ivalwe nge-mica okokuqala ngqa.
(3) Ezinye izinhlobo zesakhiwo eziyisisekelo zamajeneretha kagesi wanamuhla ziyasetshenziswa, njengesakhiwo esivaliwe sesambulela esime mpo.Amasethi okuqala angu-8 awesakhiwo lapho izigxobo kazibuthe zime ngaphandle (uhlobo lwe-pivot), futhi amasethi amabili okugcina ashintshwa abe esakhiweni esijwayelekile samanje lapho izigxobo kazibuthe zizungeza ngaphakathi (uhlobo lwensimu).
(4) Imodi eyingqayizivele yokuvusa.Eyokuqala isebenzisa amandla e-DC akhiqizwa ijeneretha ye-DC steam eseduze ukuze ijabulise.Ngemuva kweminyaka emibili noma emithathu, wonke amayunithi azosebenzisa amajeneretha amancane e-DC hydro njengama-exciter.
(5) Imvamisa ye-25Hz yamukelwe.Ngaleso sikhathi, izinga le-Ying lase-United States lalixube kakhulu, lisuka ku-16.67hz liya ku-1000fhz.Ngemva kokuhlaziya nokuyekethisa, i-25Hz yamukelwa.Le mvamisa isiphenduke imvamisa ejwayelekile kwezinye izingxenye ze-United States isikhathi eside.
(6) Esikhathini esidlule, ugesi ophehlwa yimpahla yokuphehla ugesi wawusetshenziselwa ikakhulukazi ukukhanyisa, kuyilapho ugesi ophehlwa yisiteshi sikagesi saseNiagara Falls Adams wawusetshenziselwa kakhulu amandla ezimboni.
(7) Ukuhanjiswa kwezentengiselwano okude kwezigaba ezintathu ze-AC kuye kwabonakala okokuqala, okudlale indima eyisibonelo ekudluliselweni nasekusetshenzisweni okubanzi kwezigaba ezintathu ze-AC.ngemva kweminyaka eyi-10 yokusebenza, amayunithi angu-10 5000bp akhiqiza i-turbine yamanzi esiteshini samanzi sase-Adams avuselelwe ngokuphelele futhi ashintshwa.Wonke amayunithi ayi-10 ashintshiwe kwafakwa amayunithi amasha we-1000HP kanye ne-1200V, futhi enye iyunithi entsha ye-5000P ifakiwe, ukuze umthamo ofakiwe wesiteshi samandla ufinyelele ku-105000hp.
Impi ye-AC eqondile ye-hydro generator ekugcineni yanqotshwa yi-AC.Kusukela lapho, ubungqabavu be-DC bulimele kakhulu, futhi i-AC isiqalile ukucula nokuhlasela emakethe, okuphinde kwabeka ithoni yokuthuthukiswa kwamajeneretha e-hydro esikhathini esizayo.Kodwa-ke, kufanelekile ukusho ukuthi isici esimangalisayo sesiteji sokuqala ukuthi amajeneretha e-DC hydro asetshenziswa kakhulu.Ngaleso sikhathi, kwakukhona izinhlobo ezimbili zama-DC hydro motors.Enye ijeneretha ene-low-voltage.Amajeneretha amabili axhunywe ochungechungeni futhi ashayelwa i-turbine eyodwa.Eyesibili i-high-voltage generator, eyi-pivot ephindwe kabili kanye ne-double pole generator eyabelana ngeshaft eyodwa.Imininingwane izokwethulwa esihlokweni esilandelayo.
