Geza turbine yemvura nesimba ringangoita kana kinetic simba, uye turbine yemvura inotanga kutenderera. Kana tikabatanidza jenareta kune turbine yemvura, jenareta inogona kutanga kugadzira magetsi. Kana tikasimudza mwero wemvura kuti udzikise turbine, kumhanya kweturbine kuchawedzera. Naizvozvo, iyo yakakura musiyano wechiyero chemvura, iyo yakakura simba rekinetic rinowanikwa neturbine, uye yakakwirira inoshandurwa simba remagetsi. Uyu ndiwo musimboti wekutanga wehydropower.
Iyo simba rekushandurwa kwesimba nderekuti: simba rinokwevera repamusoro pemvura inoshandurwa kuita kinetic simba rekuyerera kwemvura. Kana mvura ichiyerera kuburikidza ne turbine, simba rekinetic rinoendeswa kune turbine, uye turbine inotyaira jenareta kushandura simba rekinetic kuita simba remagetsi. Nokudaro, inzira yekushandura simba remagetsi kuita simba remagetsi.
Nekuda kweakasiyana echisikigo mamiriro ezviteshi zvehydropower, kugona uye kumhanya kwema hydro generator zvikamu zvinosiyana zvakanyanya. Kazhinji, madiki ma hydro jenareta uye anomhanyisa ma hydro jenareta anofambiswa nema turbines anowanzo tora zvakachinjika zvimiro, nepo makuru uye epakati kumhanya jenareta anowanzo tora zvimiro zvakamira. Sezvo nzvimbo dzakawanda dzemagetsi emvura dziri kure nemaguta, dzinowanzoda kupa simba kune mitoro kuburikidza nemitsara yakareba yekufambisa, naizvozvo, hurongwa hwemagetsi hunoisa mberi kwepamusoro zvinodiwa zvekushanda kugadzikana kwemagetsi emagetsi emagetsi emagetsi anofanirwa kunyatsosarudzwa; Izvo zvinodikanwa zvenguva ye inertia ye rotor yakakura. Naizvozvo, kutaridzika kwe hydro generator kwakasiyana neiyo steam turbine jenareta. Rotor dhayamita yayo yakakura uye kureba kwayo ipfupi. Iyo nguva inodiwa yekutanga uye grid yekubatanidza yehydro generator zvikamu ipfupi, uye mashandiro ekutumira anochinjika. Pamusoro pekugadzirwa kwemagetsi zvakajairika, inonyanya kukodzera peak shaving units uye emergency standby units. Iyo yakawanda yehuwandu hwemvura turbine generator units yasvika 700000 kilowatts.
Kana iri musimboti wejenareta, fizikisi yechikoro chesekondari yakajeka, uye misimboti yayo yekushanda yakavakirwa pamutemo wemagetsi induction uye mutemo wemagetsi emagetsi. Naizvozvo, iyo yakajairwa musimboti wekuvaka kwayo ndeye kushandisa yakakodzera magineti conductivity uye conductive zvinhu kugadzira magineti dunhu uye dunhu remutual electromagnetic induction kugadzira magetsi emagetsi uye kuzadzisa chinangwa chekushandura simba.
Iyo turbine jenareta yemvura inofambiswa neiyo turbine yemvura. Rotor yayo ipfupi uye gobvu, nguva inodiwa yekutanga unit uye grid yekubatanidza ipfupi, uye oparesheni yekutumira inoshanduka. Pamusoro pemagetsi ekugadzira magetsi, inonyanya kukodzera peak shaving unit uye emergency standby unit. Kuwanda kwehuwandu hwemajini ejenareta emvura turbine yasvika 800000 kilowatts.
Iyo jenareta yedhiziri inofambiswa neinjini yekupisa mukati. Inokurumidza kutanga uye iri nyore kushanda, asi mutengo wayo wekugadzira magetsi wakakwira. Inonyanya kushandiswa sesimba rekuchengetedza rekukurumidzira, kana munzvimbo idzo gidhi remagetsi rakakura risingasviki uye nhare dzemagetsi. Kugona kunobva kune akati wandei kilowatts kusvika kune akati wandei kilowatts. Iyo torque inobuda painjini yedhiziri shaft iri pasi pe periodic pulsation, saka tsaona resonance uye shaft breakage dzinofanirwa kudzivirirwa.
Iko kumhanya kweiyo hydro jenareta kucharatidza kuwanda kweiyo alternating ikozvino inogadzirwa. Kuti uone kugadzikana kweiyo frequency, kukurumidza kwe rotor kunofanirwa kudzikamiswa. Kuti ugadzikane kumhanya, kumhanya kweiyo prime mover (yemvura turbine) inogona kudzorwa mune yakavharwa loop control mode. Chiratidzo chefrequency yesimba re AC rinozotumirwa kunze rinotorwa uye kudzoserwa kudhizaini yekudzora inodzora kuvhura nekuvhara kona yegidhi vane ye turbine yemvura kudzora kubuda kwesimba re turbine yemvura. Kuburikidza nemutemo wekudzora mhinduro, kumhanya kwejenareta kunogona kudzikamiswa.
