Sukurudza turbine yemvura nesimba rinogona kukwira kana kuti kinetic energy, uye turbine yemvura inotanga kutenderera. Kana tikabatanidza jenareta neturbine yemvura, jenareta inogona kutanga kugadzira magetsi. Kana tikasimudza mwero wemvura kuti turbine ibude, kumhanya kweturbine kuchawedzera. Saka, musiyano wemvura uri mukuru, simba rekinetic rinowanikwa neturbine rinokura, uye simba remagetsi rinoshanduka rinokwira. Iyi ndiyo nheyo huru yesimba remvura.
Maitiro ekushandura simba ndeekuti: simba rekukwevera simba remvura iri kumusoro rinoshandurwa kuita simba rekufamba kwemvura. Kana mvura ikayerera nepakati peturbine, simba rekufamba rinoendeswa kuturbine, uye turbine inotyaira jenareta kuti ishandure simba rekufamba kuita simba remagetsi. Saka, inzira yekushandura simba remagetsi kuita simba remagetsi.
Nekuda kwemamiriro akasiyana ezviteshi zvemagetsi emvura, kugona uye kumhanya kwemayuniti emagetsi emvura zvinosiyana zvakanyanya. Kazhinji, majenereta madiki emvura uye majenereta emagetsi emvura anomhanya zvikuru anotungamirwa nematurbine emhepo anowanzo tora zvivakwa zvakatwasuka, nepo majenereta makuru neapakati anowanzo tora zvivakwa zvakatwasuka. Sezvo nzvimbo zhinji dzemagetsi emvura dziri kure nemaguta, dzinowanzo da kupa simba kumitoro kuburikidza nemitsetse mirefu yekutumira, saka, sisitimu yemagetsi inoisa zvinodiwa zvepamusoro zvekugadzikana kwekushanda kwemajenereta emvura: maparameter emota anofanirwa kusarudzwa nokungwarira; Zvinodiwa panguva yekusashanda kwerotor zvakakura. Naizvozvo, chitarisiko chejenereta yemvura chakasiyana nechejenereta yemhepo yemhepo. Dhayamita yayo yerotor yakakura uye kureba kwayo kupfupi. Nguva inodiwa yekutanga uye kubatanidza grid yemayuniti emagetsi emvura ipfupi, uye kutumira kwekushanda kunochinjika. Kuwedzera pakugadzira simba rese, inonyanya kukodzera mayuniti ekugera epamusoro uye mayuniti ekukurumidza. Kugona kwakanyanya kwemayuniti ejenereta emvura eturbine kwasvika 700000 kilowatts.
Kana iri nhungamiro yejenareta, fizikisi yechikoro chesekondari yakajeka, uye nhungamiro yayo inoshanda yakavakirwa pamutemo we electromagnetic induction uye mutemo we electromagnetic force. Saka, nhungamiro huru yekuvakwa kwayo ndeyekushandisa magnetic conductivity yakakodzera uye zvinhu zvinofambisa mhepo kugadzira magnetic circuit necircuit ye electromagnetic induction pamwe chete kuti igadzire simba re electromagnetic uye kuzadzisa chinangwa chekushandura simba.
Jenareta yeturbine yemvura inofambiswa neturbine yemvura. Rotor yayo ipfupi uye yakakora, nguva inodiwa yekutanga unit uye kubatanidza grid ipfupi, uye kutumira mashandiro kunochinjika. Pamusoro pekugadzira magetsi akajairika, inonyanya kukodzera unit yekugera peak uye emergency standby unit. Kugona kwakanyanya kwemayuniti ejenareta yeturbine yemvura kwasvika 800000 kilowatts.
Jenareta yedhiziri inofambiswa neinjini inobatidza mukati. Inokurumidza kutanga uye iri nyore kushandisa, asi mutengo wayo wekugadzira magetsi wakakwira. Inonyanya kushandiswa sesimba rekuchengetedza emergency, kana munzvimbo dzisina grid hombe yemagetsi uye nzvimbo dzemagetsi dzinofambiswa. Kugona kwayo kunotangira pamakilowatts akati wandei kusvika kumakilowatts akati wandei. Kubuda kwetorque pashaft yeinjini yedhiziri kunoitika nguva nenguva, saka tsaona dze resonance uye shaft dzinofanira kudzivirirwa.
Kumhanya kwejenareta remvura ndiko kuchasarudza frequency yealternating current inogadzirwa. Kuti ive nechokwadi chekuti frequency iyi yakagadzikana, kumhanya kwerotor kunofanirwa kugadzikana. Kuti kudzikamise kumhanya, kumhanya kweprime mover (water turbine) kunogona kudzorwa nenzira yekudzora yakavharika. Chiratidzo chefrequency chesimba reAC rinotumirwa chinotorwa sampuli uye chinodzoserwa kusystem yekudzora inodzora kona yekuvhura nekuvhara yeguide vane yewater turbine kuti idzore simba rekubuda kwewater turbine. Kuburikidza nepfungwa yekudzora mhinduro, kumhanya kwejenareta kunogona kugadzikana.
