Seti ya jenereta nthawi zambiri imakhala ndi injini, jenereta, makina owongolera, makina ozungulira mafuta, ndi makina ogawa mphamvu.Gawo lamphamvu la jenereta lomwe limayikidwa mu njira yolankhulirana - injini ya dizilo kapena injini yamagetsi yamagetsi - imakhala yofanana ndi mayunitsi apamwamba komanso otsika;Kukonzekera ndi kuchuluka kwa mafuta a dongosolo la mafuta makamaka kumagwirizana ndi mphamvu, kotero palibe kusiyana kwakukulu pakati pa mayunitsi apamwamba ndi otsika kwambiri, kotero palibe kusiyana pakati pa zofunikira za kayendedwe ka mpweya ndi kutulutsa mpweya wa mayunitsi omwe amapereka kuziziritsa.Kusiyana kwa magawo ndi magwiridwe antchito pakati pa ma seti a jenereta okwera kwambiri ndi ma seti otsika amagetsi otsika amawonetsedwa makamaka mu gawo la jenereta ndi gawo la dongosolo logawa.
1. Kusiyana kwa mphamvu ndi kulemera kwake
Majenereta apamwamba kwambiri amagwiritsa ntchito ma jenereta amphamvu kwambiri, ndipo kuchuluka kwa ma voltage kumapangitsa kuti zomwe amafunikira zimakwera kwambiri.Momwemonso, voliyumu ndi kulemera kwa gawo la jenereta ndizokulirapo kuposa za mayunitsi otsika.Chifukwa chake, kuchuluka kwa thupi lonse ndi kulemera kwa seti ya jenereta ya 10kV ndizokulirapo pang'ono kuposa zamagetsi otsika.Palibe kusiyana kwakukulu pamawonekedwe kupatula gawo la jenereta.
2. Kusiyanasiyana kwa njira zoyambira pansi
Njira zosalowerera zamagulu awiri a jenereta ndizosiyana.The 380V unit winding ndi nyenyezi yolumikizidwa.Nthawi zambiri, makina otsika-voltage ndi gawo losalowerera ndale, kotero nyenyezi yolumikizidwa ndi jenereta yolumikizidwa ndi gawo losalowerera ndale imayikidwa kuti ichotsedwe ndipo imatha kukhazikika pakafunika.Dongosolo la 10kV ndi kachitidwe kakang'ono kamene kamakhala pansi pano, ndipo malo osalowerera ndale nthawi zambiri samakhazikika kapena kukhazikika chifukwa cha kukana.Chifukwa chake, poyerekeza ndi mayunitsi otsika kwambiri, mayunitsi a 10kV amafunikira kuwonjezera zida zogawira mfundo zosalowerera ndale monga makabati otsutsa ndi makabati olumikizirana.
3. Kusiyana kwa njira zotetezera
High voteji jenereta akanema ambiri amafuna unsembe wa panopa chitetezo mwamsanga yopuma, chitetezo mochulukira, chitetezo grounding, etc. Pamene tilinazo panopa chitetezo yopuma mwamsanga si kukumana zofunika, kotenga nthawi chitetezo kusiyana akhoza kuikidwa.
Pamene vuto lokhazikika likuchitika pakugwira ntchito kwa jenereta yamagetsi amphamvu kwambiri, kumayambitsa chiopsezo chachikulu cha chitetezo kwa ogwira ntchito ndi zipangizo, kotero ndikofunikira kukhazikitsa chitetezo chapansi.
Mfundo yosalowerera ndale ya jenereta imakhazikitsidwa ndi resistor.Pakachitika vuto lokhazikika la gawo limodzi, vuto lomwe likuyenda mopanda ndale limatha kuzindikirika, ndipo chitetezo chopunthwa kapena kutseka chikhoza kupezedwa kudzera muchitetezo cha relay.Mfundo yosalowerera ndale ya jenereta imakhazikitsidwa ndi chotsutsa, chomwe chingathe kuchepetsa vuto lamakono mkati mwa njira yowonongeka yovomerezeka ya jenereta, ndipo jenereta ikhoza kugwira ntchito ndi zolakwika.Kupyolera mu kukana kuyika pansi, zolakwika zoyambira zimatha kuzindikirika bwino ndipo zochita zoteteza zolumikizira zimatha kuyendetsedwa.Poyerekeza ndi mayunitsi otsika-voltage, ma seti a jenereta apamwamba kwambiri amafunikira kuwonjezera zida zogawira mfundo zosalowerera ndale monga makabati otsutsa ndi makabati olumikizirana.
Ngati ndi kotheka, chitetezo chosiyana chiyenera kukhazikitsidwa pamaseti a jenereta amphamvu kwambiri.
Perekani chitetezo chosiyana cha magawo atatu pamayendedwe a stator a jenereta.Poika zosinthira zamakono pazigawo ziwiri zotuluka za koyilo iliyonse mu jenereta, kusiyana komwe kulipo pakati pa malo obwera ndi otuluka a koyilo kumayesedwa kuti mudziwe momwe koyiloyo imakhalira.Pamene dera lalifupi kapena kukhazikika kumachitika mu magawo awiri kapena atatu, vuto lamakono limatha kudziwika mu ma transformer onse, potero amayendetsa chitetezo.
4. Kusiyana kwa zingwe linanena bungwe
Pansi pamlingo womwewo, chingwe cholumikizira cha mayunitsi apamwamba kwambiri ndi ocheperako kuposa mayunitsi amagetsi otsika, kotero kuti malo ofunikira pamayendedwe otulutsira ndi otsika.
5. Kusiyana kwa Unit Control Systems
Dongosolo loyang'anira mayunitsi amagetsi otsika amatha kuphatikizidwa mbali imodzi ya gawo la jenereta pamakina a makina, pomwe mayunitsi apamwamba kwambiri amafunikira bokosi lodziyimira pawokha lodziyimira pawokha kuti likonzedwe mosiyana ndi chipangizocho chifukwa cha kusokoneza kwa ma sign.
6. Kusiyana kwa zofunikira zosamalira
Zofunikira pakukonza mayunitsi a jenereta apamwamba kwambiri pazinthu zosiyanasiyana monga dongosolo lamafuta ozungulira ndi mpweya komanso mpweya wotulutsa ndi wofanana ndi mayunitsi otsika kwambiri, koma kugawa mphamvu kwa mayunitsi ndi dongosolo lamphamvu kwambiri, komanso ogwira ntchito yosamalira. ziyenera kukhala ndi zilolezo zogwirira ntchito zamphamvu kwambiri.
