Liwiro la ma turbines amadzi ndi locheperako, makamaka loyimirira lamadzi.Kuti apange 50Hz AC, jenereta ya turbine yamadzi imagwiritsa ntchito kapangidwe ka maginito angapo.Kwa jenereta ya turbine yamadzi yozungulira 120 pamphindi, mapeyala 25 a maginito amafunikira.Chifukwa ndizovuta kuwona mapangidwe amitengo yambiri ya maginito, kosiyi ikuwonetsa mtundu wa jenereta wa hydraulic turbine wokhala ndi mapeyala 12 amitengo yamaginito.
Rotor ya hydro jenereta imatengera mawonekedwe amtengo.Chithunzi 1 chikuwonetsa goli la maginito ndi maginito a jenereta.Magnetic pole imayikidwa pa goli la maginito, yomwe ndi njira ya mzere wa magnetic field wa magnetic pole.Mtundu wa jenereta uli ndi mitengo ya maginito 24 pakati pa Kumpoto ndi kumwera, ndipo mtengo uliwonse wa maginito umabala ndi koyilo yosangalatsa.Mphamvu yachisangalalo imaperekedwa ndi jenereta yosangalatsa yomwe imayikidwa kumapeto kwa shaft yayikulu kapena njira yakunja ya thyristor excitation system (mphete yosonkhanitsa imapereka mphamvu kwa koyilo yosangalatsa).
Goli la maginito limayikidwa pa chithandizo cha rotor, shaft yaikulu ya jenereta imayikidwa pakati pa chithandizo cha rotor, ndipo jenereta yokondweretsa kapena mphete yosonkhanitsa imayikidwa kumapeto kwa shaft yaikulu.
Jenereta ya stator pachimake imapangidwa ndi zitsulo zachitsulo za silicon zokhala ndi maginito abwino, ndipo mipata yambiri imagawidwa mofanana mkati mwapakati kuti imangirire koyilo ya stator.
Koyilo ya stator imayikidwa mu kagawo ka stator kuti ipange mafunde atatu.Mapiringidwe a gawo lililonse amapangidwa ndi ma koyilo angapo ndipo amakonzedwa motsatira lamulo linalake.
Jenereta ya hydro imayikidwa pa konkriti kuthira turbine pier, ndipo pier ya turbine imayikidwa ndi maziko a turbine.Pansi pa turbine ndiye poyika maziko a stator pachimake ndi chipolopolo cha jenereta ya hydro.Chipangizo chochepetsera kutentha chimayikidwa pa chipolopolo cha turbine maziko kuti muchepetse kutentha kwa mpweya wozizira wa jenereta;Chimango chapansi chimayikidwanso pa pier.The m'munsi chimango okonzeka ndi kukankha, amene ntchito kukhazikitsa jenereta rotor.Kuwongolera kumatha kunyamula kulemera, kugwedezeka, mphamvu ndi mphamvu zina za rotor.
Pansi pake pali stator coil ndi stator coil.Rotor imayikidwa pakati pa stator ndipo ili ndi kusiyana kochepa ndi stator.Rotor imathandizidwa ndi kukankhira kwa chimango chapansi ndipo imatha kuzungulira momasuka.Chojambula chapamwamba chimayikidwa, ndipo chowongoleracho chimayikidwa pakati pa chimango chapamwamba kuti chiteteze tsinde lalikulu la jenereta kuti lisagwedezeke ndikulisunga pakatikati mokhazikika.Pambuyo kuyala nsanja yapamwamba pansi ndikuyika chipangizo cha burashi kapena injini yosangalatsa, mtundu wa hydro jenereta umayikidwa.
Mphamvu yama electromotive ya magawo atatu a AC yozungulira 12 idzapangitsidwa ndi kuzungulira kwa rotor yachitsanzo ya jenereta ya hydro.Pamene liwiro la rotor ndi kusinthika kwa 250 pamphindi, mafupipafupi a AC opangidwa ndi 50 Hz.
