Isivinini samaturbines amanzi siphansi, ikakhulukazi i-turbine yamanzi emile. Ukuze kukhiqizwe i-50Hz AC, ijeneretha ye-turbine yamanzi isebenzisa ukwakheka kwezigxobo ezihlukene kazibuthe. Kujeneretha ye-turbine yamanzi enokuphenduka okungu-120 ngomzuzu, amapheya angama-25 ezigxobo kazibuthe ayadingeka. Ngenxa yokuthi kunzima ukubona ukwakheka kwezigxobo kazibuthe eziningi kakhulu, le courseware yethula imodeli ye-hydraulic turbine generator enamapheya angu-12 ezigxobo kazibuthe.
I-rotor ye-hydro generator isebenzisa ukwakheka kwesigxobo esibalulekile. Umfanekiso 1 ubonisa ijoka kazibuthe kanye nesigxobo kazibuthe se-generator. Isigxobo kazibuthe sifakwe ejokeni kazibuthe, okuyindlela yomugqa wensimu kazibuthe yesigxobo kazibuthe. Imodeli yejeneretha inezigxobo kazibuthe ezingu-24 phakathi kweNyakatho neningizimu, futhi isigxobo ngasinye sikazibuthe sinenxeba ngekhoyili evusa amadlingozi. Amandla avusa amadlingozi anikezwa ijeneretha evusa amadlingozi efakwe ekugcineni kwe-shaft eyinhloko noma uhlelo lwe-excitation lwe-thyristor lwangaphandle (indandatho yokuqoqa inikeza amandla kukhoyili yokuvusa).
Ijoka lamagnetic lifakwe ekusekelweni kwe-rotor, i-shaft eyinhloko ye-generator ifakwe phakathi nendawo yokusekelwa kwe-rotor, futhi i-generator yokuvuselela noma indandatho yokuqoqa ifakwe ekugcineni okuphezulu kwe-shaft enkulu.
I-generator stator core yenziwe ngamashidi ensimbi ye-silicon ane-conductivity kazibuthe enhle, futhi izikhala eziningi zisakazwa ngokulinganayo kumbuthano ongaphakathi womongo ukuze ushumeke ikhoyili ye-stator.
Ikhoyili ye-stator ishumekwe ku-stator slot ukuze yakhe ukuphenduka kwezigaba ezintathu. Ukujika kwesigaba ngasinye kwakhiwe amakhoyili amaningi futhi ahlelwe ngokomthetho othile.
I-hydro generator ifakwe ku-pier ye-turbine ethela ukhonkolo, futhi i-turbine pier ifakwe nesisekelo se-turbine. Isizinda se-turbine yisisekelo sokufakwa kwe-stator core kanye negobolondo le-hydro generator. Idivayisi yokukhipha ukushisa ifakwe egobolondweni lesizinda se-turbine ukunciphisa izinga lokushisa lomoya opholile we-generator; Uhlaka olungezansi nalo lufakwe ku-pier. Uhlaka olungezansi lufakwe i-thrust bear, esetshenziselwa ukufaka i-rotor ye-generator. I-thrust bear ithwala isisindo, ukudlidliza, umthelela namanye amandla e-rotor.
I-stator core kanye nekhoyili ye-stator ifakwe esisekelweni. I-rotor ifakwe phakathi kwe-stator futhi ine-gap encane ne-stator. I-rotor isekelwa i-thrust bear yohlaka oluphansi futhi ingajikeleza ngokukhululekile. Kufakwe ifreyimu engenhla, futhi igayidi elithwalayo lifakwa phakathi nendawo yohlaka olungaphezulu ukuze kuvinjwe i-shaft eyinhloko ye-generator ukuthi inganyakazi futhi igcinwe endaweni emaphakathi ngokuzinzile. Ngemva kokubeka indawo engaphezulu yesikhulumi nokufaka idivayisi yebhulashi noma injini evusa amadlingozi, kufakwa imodeli ye-hydro generator.
Amandla e-AC ezigaba ezintathu zemijikelezo engu-12 azobangelwa ukuzungezisa kwemodeli yerotha yejeneretha yamanzi. Lapho isivinini se-rotor singama-revolutions angu-250 ngomzuzu, imvamisa ye-AC ekhiqiziwe ingu-50 Hz.
