Isethi yejeneretha kagesi ngamanzi iyithuluzi lokuguqula amandla eliguqula amandla angaba khona amanzi abe amandla kagesi. Ngokuvamile lakhiwe yi-turbine yamanzi, ijeneretha, i-governor, uhlelo lokuvuselela, uhlelo lokupholisa kanye nemishini yokulawula isiteshi samandla.
(1) I-Hydraulic turbine: kunezinhlobo ezimbili zama-hydraulic turbine ezivame ukusetshenziswa: uhlobo lwe-impulse kanye nohlobo lokusabela.
(2) Ijenereyitha: iningi lamajenereyitha liyijenereyitha ezihambisanayo, ezinejubane eliphansi, ngokuvamile lingaphansi kuka-750r/min, kanti ezinye zinezijikelezo/umzuzu eziyishumi nambili kuphela; Ngenxa yejubane eliphansi, kunezinsika eziningi zamagnetic; Usayizi wesakhiwo esikhulu kanye nesisindo; Kunezinhlobo ezimbili zokufakwa kwamayunithi ejenereyitha ye-hydraulic: eqondile neqondile.
(3) Amadivayisi okulawula isivinini (kufaka phakathi i-speed governor kanye nedivayisi yokucindezela uwoyela): indima ye-speed governor ukulawula ijubane le-hydraulic turbine, ukuqinisekisa ukuthi imvamisa yamandla kagesi aphumayo ihlangabezana nezidingo zokuphakelwa kwamandla, kanye nokufeza ukusebenza kweyunithi (ukuqala, ukuvala, ukushintsha isivinini, ukwanda komthwalo kanye nokwehla komthwalo) kanye nokusebenza okuphephile nokonga imali. Ngakho-ke, ukusebenza kwe-governor kufanele kuhlangabezane nezidingo zokusebenza okusheshayo, impendulo ebucayi, ukuzinza okusheshayo, ukusebenza okulula kanye nokugcinwa, futhi kudinga nokusebenza ngesandla okuthembekile kanye namadivayisi okuvala okuphuthumayo.
(4) Uhlelo lokuvusa: ijeneretha ye-hydraulic ngokuvamile iyijeneretha ehambisanayo kagesi. Ngokulawulwa kohlelo lokuvusa lwe-DC, ukulawulwa kwamandla kagesi, ukulawulwa kwamandla asebenzayo kanye namandla asabelayo kanye nezinye izilawuli kungafinyelelwa ukuze kuthuthukiswe ikhwalithi yamandla kagesi aphumayo.
(5) Uhlelo Lokupholisa: Ukupholisa umoya kusetshenziselwa kakhulu ijenereyitha encane ye-hydraulic ukupholisa i-stator, i-rotor kanye ne-iron core ebusweni bejenereyitha ngesistimu yokungenisa umoya. Kodwa-ke, ngokwanda komthamo weyunithi eyodwa, imithwalo yokushisa ye-stator kanye ne-rotor iyanda njalo. Ukuze kwandiswe amandla okukhipha ngeyunithi ngayinye yejenereyitha ngesivinini esithile, ijenereyitha ye-hydraulic enamandla amakhulu isebenzisa imodi yokupholisa amanzi ngqo ye-stator kanye ne-rotor windings; Noma i-stator winding ipholiswa ngamanzi, kuyilapho i-rotor ipholiswa ngumoya onamandla.
(6) Imishini yokulawula isiteshi sikagesi: imishini yokulawula isiteshi sikagesi isekelwe kakhulu kumakhompyutha amancane, eqaphela imisebenzi yokuxhumeka kwegridi, ukulawulwa kwamandla kagesi, ukuguqulwa kwamaza, ukulawulwa kwamandla, ukuvikelwa kanye nokuxhumana kwamajeneretha e-hydraulic.
(7) Idivayisi yokubhuleka: wonke amajeneretha e-hydraulic anomthamo olinganiselwe odlula inani elithile afakwe idivayisi yokubhuleka, esetshenziselwa ukubhuleka i-rotor njalo lapho ijubane lehliswa libe ngu-30% ~ 40% wejubane elilinganiselwe ngesikhathi sokuvala ijeneretha, ukuze kuvinjelwe ukuthi i-thrust bearing ingashi ngenxa yomonakalo wefilimu kawoyela ngesivinini esiphansi. Omunye umsebenzi wedivayisi yokubhuleka ukufaka uwoyela ocindezelayo ezingxenyeni ezijikelezayo zejeneretha ngaphambi kokufakwa, ukulungiswa kanye nokuqala. Idivayisi yokubhuleka isebenzisa umoya ocindezelwe ukubhuleka
