Kodi Zifukwa Zotani Zakuvuta Kwambiri Kwa Hydro Jenereta

Mafupipafupi a AC samakhudzana mwachindunji ndi liwiro la injini ya hydropower station, koma amagwirizana mwachindunji.
Ziribe kanthu kuti ndi mtundu wanji wa zida zopangira mphamvu, zimafunika kutumiza mphamvu ku gridi yamagetsi pambuyo popanga mphamvu, ndiko kuti, jenereta iyenera kulumikizidwa ku gridi yopangira mphamvu.Pambuyo polumikizidwa ndi gridi, imalumikizidwa ndi gridi yamagetsi yonse, ndipo ma frequency paliponse mu gridi yamagetsi ndi chimodzimodzi.Kukula kwa gridi yamagetsi, kumachepetsa kusinthasintha kwafupipafupi komanso kukhazikika kwafupipafupi.Komabe, ma frequency a gridi yamagetsi amangogwirizana ndi ngati mphamvu yogwira imagwira ntchito moyenera.Pamene mphamvu yogwira ntchito yopangidwa ndi jenereta yowonjezera imakhala yaikulu kuposa mphamvu yogwira ntchito yamagetsi, mafupipafupi a gridi yamagetsi adzawonjezeka, ndipo mosiyana.
Mphamvu yogwira ntchito ndi vuto lalikulu la gridi yamagetsi.Chifukwa kuchuluka kwa mphamvu kwa ogwiritsa ntchito kumasinthasintha nthawi zonse, gridi yamagetsi iyenera kuwonetsetsa kutulutsa kwamagetsi ndi kuchuluka kwa katundu.Kugwiritsa ntchito kofunikira kwambiri kwa hydropower station mumagetsi amagetsi ndikusinthasintha pafupipafupi.Zachidziwikire, mphamvu yayikulu kwambiri yamadzi ya Mitsinje itatu imagwiritsidwa ntchito kwambiri popangira magetsi.Poyerekeza ndi mitundu ina ya malo opangira magetsi, malo opangira magetsi amadzi ali ndi maubwino ake pakusinthasintha pafupipafupi.Makina opangira madzi amatha kusintha mwachangu liwiro, lomwe limatha kusinthanso mphamvu yogwira komanso yotakataka ya jenereta, kuti muzitha kuwongolera kuchuluka kwa gululi, pomwe mphamvu yamafuta ndi mphamvu ya nyukiliya imasintha injiniyo pang'onopang'ono.Malingana ngati mphamvu yogwira ntchito ya gridi yamagetsi ndi yabwino, voteji imakhala yokhazikika.Chifukwa chake, malo opangira magetsi a hydropower amathandizira kwambiri kukhazikika pafupipafupi kwa gridi yamagetsi.

Pakali pano, malo ambiri ang'onoang'ono ndi apakatikati opangira mphamvu zamagetsi ku China ali pansi pa gridi yamagetsi.Gululi lamagetsi liyenera kukhala ndi mphamvu zonse pamagetsi akuluakulu osinthira ma frequency modulation, kuti zitsimikizire kukhazikika kwa grid yamagetsi pafupipafupi ndi voteji.Mwachidule:
1. Gulu lamagetsi limatsimikizira kuthamanga kwa injini.Tsopano timagwiritsa ntchito ma synchronous motors popanga mphamvu, ndiko kuti, kusintha kwamphamvu kumakhala kofanana ndi gridi yamagetsi, ndiye kuti, nthawi 50 pamphindi imodzi.Kwa jenereta yamagetsi yotentha yokhala ndi maelekitirodi amodzi okha, imazungulira kuzungulira kwa 3000 pamphindi.Kwa jenereta ya hydropower plant yokhala ndi n ma electrode, imazungulira 3000 / N mu mphindi imodzi.Makina opangira madzi ndi jenereta nthawi zambiri amalumikizidwa palimodzi kudzera pamakina opatsirana okhazikika, motero tinganene kuti amatsimikiziridwa ndi ma frequency a gridi yamagetsi.
2. Kodi ntchito yoyendetsera madzi ndi yotani?Sinthani kutulutsa kwa jenereta, ndiko kuti, mphamvu yotumizidwa ndi jenereta ku gridi yamagetsi.Nthawi zambiri, mphamvu inayake imafunika kuti jenereta ifike pa liwiro lake, koma jenereta ikangolumikizidwa ndi gridi yamagetsi, liwiro la jenereta limatsimikiziridwa ndi ma frequency a gridi yamagetsi.Pakadali pano, nthawi zambiri timaganiza kuti ma frequency a gridi yamagetsi sasintha.Mwa njira iyi, mphamvu ya jenereta ikadutsa mphamvu yofunikira kuti ikhale yothamanga mofulumira, jenereta imatumiza mphamvu ku gridi ndikuyamwa mphamvu mosiyana.Choncho, pamene galimoto imapanga mphamvu pansi pa katundu wolemetsa, ikangochotsedwa ku galimotoyo, liwiro lake lidzawonjezeka mofulumira kuchokera pa liwiro lovomerezeka mpaka kangapo, zomwe zimakhala ndi ngozi zowuluka!
3. Mphamvu yopangidwa ndi jenereta idzakhudzanso ma frequency a grid, ndipo ma hydropower unit nthawi zambiri amagwiritsidwa ntchito ngati ma frequency modulation mayunitsi chifukwa cha kuchuluka kwa malamulo.
