Hydroelectric generator set isimba rekushandura simba rinoshandura simba remvura kuita simba remagetsi. Iyo inowanzo umbwa nemvura turbine, jenareta, gavhuna, excitation system, inotonhorera sisitimu uye magetsi chiteshi chekudzora michina.
(1) Hydraulic turbine: kune marudzi maviri e hydraulic turbines anowanzoshandiswa: impulse type uye reaction type.
(2) Jenareta: majenareta mazhinji ari synchronous generator, ane low speed, kazhinji pazasi 750r/min, uye mamwe anongova nemarevolutions/miniti; Nekuda kwekumhanya kwakaderera, kune akawanda magineti mapango; Kukura kwechimiro chakakura uye uremu; Kune marudzi maviri ekuiswa kwehydraulic generator units: vertical uye horizontal.
(3) Yekumhanyisa kudzora uye kudzora zvishandiso (kusanganisira kumhanya gavhuna uye oiri yekumanikidza mudziyo): basa reanomhanyisa gavhuna ndere kudzora kumhanya kweiyo hydraulic turbine, kuitira kuti ive nechokwadi chekuti frequency yekubuda kwesimba remagetsi rinosangana nezvinodiwa zvemagetsi emagetsi, uye kuwana mashandiro eyuniti (kutanga, kudzima, kukurumidza kuchinja, kuwedzera mutoro uye kuderera kwekuita basa) uye yakachengeteka uye yehupfumi kushanda. Naizvozvo, kuita kwegavhuna kunosangana nezvinodiwa zvekukurumidza kushanda, mhinduro inonzwisisika, kugadzikana nekukurumidza, kushanda kwakaringana uye kugadzirisa, uye inodawo yakavimbika manyorerwo ekushandisa uye emergency shutdown zvishandiso.
(4) Excitation system: iyo hydraulic jenareta inowanzova yemagetsi synchronous jenareta. Kuburikidza nekutonga kweiyo DC excitation system, iyo voltage regulation yesimba remagetsi, kudzora kwesimba rinoshanda uye reactive simba uye zvimwe zvinodzora zvinogona kuwanikwa kuvandudza kunaka kwekubuda kwesimba remagetsi.
(5) Inotonhorera sisitimu: kutonhora kwemhepo kunonyanya kushandiswa kune diki hydraulic jenareta kutonhorera stator, rotor uye iron core pamusoro pejenareta ine ventilation system. Zvisinei, nekuwedzera kweimwe unit unit simba, iyo inopisa mitoro ye stator uye rotor inoramba ichiwedzera. Kuti uwedzere simba rinobuda pachikwata chejenereta pane imwe nguva, iyo huru ye hydraulic generator inotora nzira yakananga yekutonhora kwemvura ye stator uye rotor windings; Kana kuti stator winding inotonhorera nemvura, asi rotor inotonhorera nemhepo ine simba.
(6) Magetsi chiteshi chekudzora midziyo: iyo magetsi chiteshi chekudzora midziyo inonyanya kuenderana neiyo microcomputer, iyo inoziva mabasa ekubatanidza grid, voltage regulation, frequency modulation, simba factor regulation, kuchengetedza uye kutaurirana kwe hydraulic jenareta.
(7) Braking mudziyo: ese ma hydraulic jenareta ane chiyero chakayerwa chinodarika imwe kukosha ane akashongedzerwa braking mudziyo, iyo inoshandiswa kuramba ichipwanya rotor kana kumhanya kunoderedzwa kusvika 30% ~ 40% yeyero yakayerwa kumhanya panguva yekuvharwa kwejenareta, kuitira kudzivirira iyo yekusundidzira kubva pakupisa nekuda kwekukuvadzwa kwefirimu remafuta pakumhanya kwakaderera. Rimwe basa reiyo braking mudziyo ndeyekumhanyisa zvikamu zvinotenderera zvejenareta nemafuta ekudzvanya-kudzvanya kusati kwaiswa, kugadzirisa uye kutanga. Chishandiso chebhureki chinoshandisa mweya wakadzvanywa pakubhureki
