Jenereta Reverse Power Maintenance

Kuyika mawerengedwe a turbine yosinthira mphamvu yosinthira mphamvu ndikutsimikizira mphamvu ya Pdz ndikuchedwa kuchitapo kanthu T pakukonza.

1. Mphamvu yamphamvu ya Pdz set turbogenerator inverse yokonza mphamvu yokonza mphamvu imatha kuwerengedwa motsatira njira iyi: Pdz=(Krel*P1)/η Pdz- inverse power maintenance operation power Krel- reliability coefficient, kutenga 0.8 P1- mphamvu yogwiritsidwa ntchito ndi turbine kusunga synchronous kasinthasintha liwiro pambuyo valavu chachikulu chatsekedwa, kukula kwa mphamvu imeneyi zikugwirizana ndi kapangidwe ndi mphamvu ya turbine, Zimagwirizananso ndi kamangidwe ka nthunzi yaikulu dongosolo turbogenerator (mapangidwe a payipi ndi kaya pali payipi yodutsa, etc.).Nthawi zambiri, mphamvu yovotera ndi 1.5~2% η- mphamvu ya jenereta pamene jenereta imakoka turbogenerator kuti izungulira, ndi 0.98~0.99, kotero: Pdz≈ (1.2~1.6%) PN PN- mphamvu yovotera ya jenereta. .Pochita, Pdz = ikhoza kukhala 1-1.5% PN.

2.Kuchedwa kuchitapo kanthu jenereta Kuchedwerako kwa mphamvu yosinthira mphamvu, kuyenera kukhala molingana ndi jenereta ya turbine ya nthunzi pambuyo valavu yayikulu yotsekedwa yololedwa kugwiritsa ntchito nthawi yoyika, nthawi yololedwa nthawi zambiri imakhala 10 ~ 15min.Mawerengedwe ndi machitidwe ogwirira ntchito akuwonetsa kuti pamene makina opangira nthunzi opangira nthunzi ali ndi chitoliro chodutsa, nthawi yogwira ntchito iyenera kukhala yayitali.Choncho, ngati kuchedwa kwa ntchito yokonza kumayikidwa molingana ndi nthawi yomwe imaloledwa kuthamanga pambuyo poti valavu yayikulu ya turbine yatsekedwa, 5 ~ 10min ndiyoyenera.Pambuyo pakuchita, imagwiritsidwa ntchito pochotsa maginito.

Kuphatikiza apo, ma turbogenerators akulu omwe akugwira ntchito nthawi zambiri amagwiritsa ntchito kukonza mphamvu zobwerera kumbuyo kuti ayambitse pulogalamu yaulendo.Pakadali pano, nthawi yochitapo nthawi zambiri imatenga 1 ~ 2s.Pakukonza mphamvu zoyendetsedwa ndi pulogalamu, chifukwa nthawi yogwira ntchito ndi yochepa, pakangopita nthawi yochepa kwambiri valavu yayikulu itatsekedwa, chifukwa cha inertia ya turbine ndi jenereta, mphamvu yogwiritsa ntchitoyo ikhoza kukhala yaying'ono kwambiri, mtengo wokhazikika wa mphamvu yosinthira siyenera kupitilira 1% PN.

Chiyambi cha mfundoyi

Pamene jenereta ali n'zosiyana mphamvu (zigawo mphamvu kunja kwa jenereta, ndiye jenereta amakhala chikhalidwe galimoto), n'zosiyana mphamvu yokonza ntchito dera wosweka maulendo.Kufuna kumasonkhanitsa ma voltages a magawo atatu ndi ma sign apano a magawo awiri.

Chifukwa cha mitundu yosiyanasiyana ya mphamvu zoyambira, ma jenereta osiyanasiyana amatha kupangidwa.Kugwiritsa ntchito zinthu zamadzi ndi mgwirizano wa makina opangira madzi, zitha kupangidwa kukhala jenereta yamadzi;Chifukwa cha kusiyana kwa mphamvu yosungiramo madzi ndi kutsika kwa mutu, ma hydro-generator okhala ndi mphamvu zosiyana ndi liwiro amatha kupangidwa.Pogwiritsa ntchito malasha, mafuta ndi zinthu zina komanso kugwirizana ndi ma boilers ndi injini za turbo-steam, majenereta a turbo amatha kupangidwa, omwe nthawi zambiri amakhala othamanga kwambiri (3000rpm).Kuonjezera apo, pali mitundu yonse ya majenereta omwe amagwiritsa ntchito mphamvu ya dzuwa, mphamvu ya mphepo, mphamvu ya atomiki, mphamvu ya geothermal, mphamvu yamadzi, mphamvu zamoyo ndi zina zotero.Kuphatikiza apo, chifukwa mfundo yoyendetsera jenereta ndi yosiyana ndipo imagawidwa kukhala jenereta ya dc, jenereta ya asynchronous ndi jenereta yolumikizana.Mu ambiri ntchito lalikulu jenereta ndi synchronous jenereta.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. unakhazikitsidwa mu 2006, ndi Mlengi wa jenereta dizilo ku China, amene integrates kamangidwe, kupereka, kutumiza ndi kukonza dizilo jenereta seti.Zogulitsa zimaphatikizapo Cummins, Perkins, Volvo , Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai etc. ndi mphamvu osiyanasiyana 20kw-3000kw, ndi kukhala fakitale OEM ndi pakati luso.
