Jenereta ndi mota zimadziwika ngati mitundu iwiri ya zida zamakina.Imodzi ndikusintha mphamvu zina kukhala mphamvu yamagetsi yopangira mphamvu, pomwe injiniyo imatembenuza mphamvu yamagetsi kukhala mphamvu yamakina kuti ikoke zinthu zina.Komabe, awiriwo sangathe kukhazikitsidwa ndi kusinthidwa wina ndi mzake.Mitundu ina ya ma jenereta ndi ma mota amatha kusinthana pambuyo pakupanga ndi kusinthidwa.Komabe, ngati pakhala cholakwika, jenereta imasinthidwanso kukhala ntchito yamagalimoto, yomwe ndi chitetezo cham'mbuyo pansi pa mphamvu yosinthira ya jenereta yomwe tikufuna kukambirana lero.
Kodi reverse mphamvu ndi chiyani?
Monga tonse tikudziwira, mphamvu ya jenereta iyenera kuyenda kuchokera ku njira ya jenereta kupita ku dongosolo.Komabe, pazifukwa zina, pamene turbine itaya mphamvu yachisonkhezero ndipo chosinthira cha jenereta chikulephera kuyenda, njira yamagetsi imasintha kuchokera ku dongosolo kupita ku jenereta, ndiko kuti, jenereta imasintha kukhala injini yomwe ikugwira ntchito.Panthawi imeneyi, jenereta imatenga mphamvu yogwira ntchito kuchokera ku dongosolo, lomwe limatchedwa reverse power.
Kuwonongeka kwa mphamvu yobwerera
Kutetezedwa kwa mphamvu ya jenereta ndikuti pamene valavu yayikulu ya turbine ya nthunzi yatsekedwa chifukwa chazifukwa zina ndipo mphamvu yapachiyambi itayika, jeneretayo imasandulika kukhala injini yoyendetsa makina opangira nthunzi kuti azungulire.Kuthamanga kwambiri kwa tsamba la turbine la nthunzi popanda nthunzi kumayambitsa kuphulika kwa mphepo, makamaka pa tsamba lomaliza, kungayambitse kutenthedwa ndi kuchititsa ngozi yowonongeka kwa tsamba la rotor.
Chifukwa chake, chitetezo chosinthira mphamvu ndiye chitetezo cha turbine ya nthunzi popanda kugwiritsa ntchito nthunzi.
Kutetezedwa kwamagetsi osinthika a jenereta
Pulogalamu ya jenereta yoteteza mphamvu makamaka kuteteza jenereta kuti isagwedezeke mwadzidzidzi chosinthira chotulutsa jenereta pansi pa katundu wina wake ndipo valavu yayikulu ya turbine ya nthunzi sinatsekedwe kwathunthu.Pankhaniyi, gawo la jenereta la turbine la nthunzi limakonda kuthamanga kwambiri komanso kuthamanga kwambiri.Pofuna kupewa izi, pazitetezero zina popanda vuto laling'ono, chizindikirocho chikatumizidwa, chimayamba kuchitapo kanthu potseka valavu yayikulu ya turbine ya nthunzi.Pambuyo pa mphamvu yobwereranso * * * ya machitidwe a jenereta, imapanga ndi valavu ndi chizindikiro chotseka valavu yaikulu ya nthunzi, kupanga pulogalamu yotetezera mphamvu pambuyo pa nthawi yochepa, ndipo zochitazo zidzachitapo kanthu.
Kusiyana pakati pa chitetezo cha reverse mphamvu ndi chitetezo cha reverse mphamvu
Kuteteza mphamvu kumbuyo ndikuletsa jenereta kuti isatembenuke kukhala mota pambuyo pa mphamvu yobwerera kumbuyo, kuyendetsa makina opangira nthunzi kuti azungulire ndikupangitsa kuwonongeka kwa turbine ya nthunzi.Pomaliza, ndikuwopa kuti wotsogolera wamkulu adzayendetsedwa ndi dongosolo ngati alibe mphamvu!
Chitetezo champhamvu cha pulogalamuyo ndikuletsa kuthamangitsidwa kwa turbine chifukwa cha valavu yayikulu yosatsekeka pambuyo poti jenereta yatha mwadzidzidzi, ndiye kuti mphamvu yakumbuyo imagwiritsidwa ntchito kupewa.Pamapeto pake, ndikuwopa kuti mphamvu zochulukirapo za woyendetsa wamkulu zitha kupangitsa kuti gawoli likhale lothamanga kwambiri.
Choncho, kunena mosamalitsa, reverse mphamvu chitetezo ndi mtundu wa jenereta relay chitetezo, koma makamaka kuteteza nthunzi chopangira magetsi.Kuteteza mphamvu kwa pulogalamuyo sikuteteza, koma ndi njira yomwe imakhazikitsidwa kuti iwonetsetse kuyendetsa pulogalamu, yomwe imadziwikanso kuti pulogalamu yodutsa, yomwe nthawi zambiri imagwiritsidwa ntchito potseka.
Chofunikira ndichakuti bola mphamvu yakumbuyo ikafika pamtengo wokhazikitsidwa, idzayenda.Kuphatikiza pakufikira mtengo wokhazikitsidwa, mphamvu yosinthira pulogalamuyo imafunanso kuti valavu yayikulu ya turbine ya nthunzi itsekedwe.Chifukwa chake, kugwiritsa ntchito mphamvu zakumbuyo kuyenera kupewedwa panthawi yolumikizana ndi grid panthawi yoyambira.
Izi ndi ntchito za chitetezo chosinthira jenereta komanso kufotokozera mphamvu yosinthira jenereta.Kwa jenereta ya turbine mu gululi yolumikizidwa, imagwira ntchito ngati injini yolumikizana pambuyo poti valavu yayikulu ya turbine ya nthunzi yatsekedwa: kuyamwa mphamvu yogwira ndikukokera makina opangira nthunzi kuti azungulire, zomwe zimatha kutumiza mphamvu zotakataka kudongosolo.Pamene valavu yaikulu ya turbine ya nthunzi yatsekedwa, tsamba la mchira wa turbine ya nthunzi imakangana ndi nthunzi yotsalira kuti iwonongeke, yomwe imawonongeka chifukwa cha kutentha kwa nthawi yaitali.Panthawi imeneyi, chitetezo cham'mbuyo chimatha kuteteza turbine ya nthunzi kuti isawonongeke.
