Mu nkhani yomaliza, tinapereka chigamulo cha DC AC. "Nkhondo" inatha ndi kupambana kwa AC. Chifukwa chake, AC idapeza kasupe wa chitukuko cha msika ndipo inayamba kutenga msika womwe kale unali ndi DC. Pambuyo pa "nkhondo" iyi, DC ndi AC adapikisana pa siteshoni yamagetsi ya Adams ku Niagara Falls.
Mu 1890, dziko la United States linamanga siteshoni yamagetsi ya Niagara Falls Adams. Pofuna kuyesa njira zosiyanasiyana za AC ndi DC, bungwe la Niagara Power Commission la dziko lonse komanso lapadziko lonse lapansi linakhazikitsidwa. Westinghouse ndi Ge adatenga nawo gawo pampikisano. Pomaliza, ndi mbiri yake yokwera pambuyo pa kupambana kwa nkhondo ya AC / DC ndi luso la gulu la asayansi abwino kwambiri monga Tesla, komanso kuyesa bwino kwa kutumiza kwa AC ku Great Barrington mu 1886 ndikugwira bwino ntchito kwa alternator mu chomera chamagetsi cha larffen ku Germany, Westinghouse pomaliza pake idapambana pangano lopanga majenereta 10 a 5000P AC hydro. Mu 1894, jenereta yoyamba ya 5000P ya siteshoni yamagetsi ya Niagara Falls Adams idabadwa ku Westinghouse. Mu 1895, gawo loyamba lidayamba kugwira ntchito. Mu nthawi yophukira ya 1896, mphamvu yosinthira magawo awiri yopangidwa ndi jeneretayo idasinthidwa kukhala magawo atatu kudzera mu transformer ya Scot, kenako idatumizidwa ku Baffalo pamtunda wa makilomita 40 kudzera mu njira yotumizira magawo atatu.
Jenereta yamadzi ya siteshoni yamagetsi ya Adams ku Niagara Falls idapangidwa ndi BG lamme (1884-1924), mainjiniya wamkulu wa Westinghouse, malinga ndi patent ya Tesla, ndipo mlongo wake B. lamme nawonso adachita nawo kapangidwe kake. Chipangizochi chimayendetsedwa ndi turbine ya fournellon (yothamanga kawiri, yopanda chubu chowongolera), ndipo jenereta ndi jenereta yolumikizana ya magawo awiri, 5000hp, 2000V, 25Hz, 250r / mln. Jenereta ili ndi makhalidwe otsatirawa;
(1) Mphamvu yayikulu komanso kukula kwake kwakutali. Zisanachitike izi, mphamvu ya hydro generator ya unit imodzi sinali yoposa 1000 HPA. Tinganene kuti hydro generator ya 5000bp ya siteshoni yamagetsi ya Adar ku Niagara Falls sinali jenereta yayikulu kwambiri ya hydro yokhala ndi mphamvu ya unit imodzi padziko lonse lapansi panthawiyo, komanso gawo loyamba lofunikira pakupanga hydro generator kuyambira yaying'ono mpaka yayikulu.
(2) Chowongolera cha armature chimatetezedwa ndi mica koyamba.
(3) Mitundu ina yoyambira ya ma hydro generator amakono imagwiritsidwa ntchito, monga mawonekedwe otsekedwa ndi ambulera yoyima. Ma seti 8 oyamba ndi a kapangidwe kamene ma poles a maginito amakhala osakhazikika kunja (mtundu wa pivot), ndipo ma seti awiri omaliza amasinthidwa kukhala kapangidwe kamene kalikonse komwe ma poles a maginito amazungulira mkati (mtundu wamunda).
(4) Njira yapadera yosonkhezera. Yoyamba imagwiritsa ntchito mphamvu ya DC yopangidwa ndi jenereta ya turbine ya nthunzi ya DC yapafupi kuti isonkhezere. Pakatha zaka ziwiri kapena zitatu, mayunitsi onse adzagwiritsa ntchito majenereta ang'onoang'ono a DC hydro ngati zosonkhezera.
(5) Ma frequency a 25Hz adagwiritsidwa ntchito. Panthawiyo, Ying rate ya ku United States inali yosiyana kwambiri, kuyambira 16.67hz mpaka 1000fhz. Pambuyo pofufuza ndi kuvomereza, 25Hz idagwiritsidwa ntchito. Ma frequency awa akhala ma frequency wamba m'malo ena a United States kwa nthawi yayitali.
(6) Kale, magetsi opangidwa ndi zida zopangira magetsi ankagwiritsidwa ntchito makamaka powunikira, pomwe magetsi opangidwa ndi siteshoni yamagetsi ya Niagara Falls Adams ankagwiritsidwa ntchito makamaka popereka magetsi m'mafakitale.
(7) Kutumiza kwa malonda kwa AC ya magawo atatu kwachitika koyamba, zomwe zakhala chitsanzo chabwino pakutumiza ndi kugwiritsa ntchito kwambiri AC ya magawo atatu. Patatha zaka 10 akugwira ntchito, mayunitsi 10 a jenereta ya turbine yamadzi ya 5000bp ya siteshoni yamagetsi ya Adams asinthidwa mokwanira ndikusinthidwa. Mayunitsi onse 10 asinthidwa ndi mayunitsi atsopano a 1000HP ndi 1200V, ndipo unit ina yatsopano ya 5000P yayikidwa, kotero kuti mphamvu yonse ya siteshoni yamagetsi ifike pa 105000hp.
Nkhondo ya AC yolunjika ya hydro generator potsiriza idagonjetsedwa ndi AC. Kuyambira pamenepo, mphamvu ya DC yawonongeka kwambiri, ndipo AC yayamba kuimba ndikuukira pamsika, zomwe zakhazikitsanso njira yopangira ma hydro generator mtsogolo. Komabe, ndikofunikira kunena kuti chinthu chodziwika bwino pagawo loyamba ndichakuti ma DC hydro generator amagwiritsidwa ntchito kwambiri. Panthawiyo, panali mitundu iwiri ya ma DC hydro motors. Chimodzi ndi jenereta yamagetsi otsika. Ma jenereta awiri amalumikizidwa motsatizana ndipo amayendetsedwa ndi turbine imodzi. Chachiwiri ndi jenereta yamagetsi okwera, yomwe ndi jenereta yamagetsi awiri ndi ya pole ziwiri yogawana shaft imodzi. Tsatanetsatane udzafotokozedwa m'nkhani yotsatira.
