Chidziwitso: Ma seti amagetsi otsika ndi omwe amasankha magetsi adzidzidzi kwa ogwiritsa ntchito ambiri, ndipo mtundu uwu nthawi zambiri umatanthawuza ma seti a 230V/400V omwe amagwiritsidwa ntchito kwambiri pamsika.Komabe, m'madera ena, chifukwa cha mtunda wa pakati pa chipinda cha jenereta ya dizilo ndi zipangizo zamagetsi, madontho a magetsi amatha kuchitika, zomwe zimapangitsa kuti magetsi asamagwiritse ntchito bwino, ndipo nthawi zambiri, ngakhale kuyatsa zipangizo zamagetsi.Chifukwa chake, kwa ogwiritsa ntchito omwe agula kale ma seti a jenereta a dizilo otsika, kuchitapo kanthu kuti mukweze kuchokera kupsinjika mpaka kupsinjika kwambiri kumakhala njira yabwino kwambiri, kuti musachotse jenereta yoyambira yotsika kwambiri ndikupangitsa kuwonongeka kwakukulu kwachuma.
1, Kuyerekeza ubwino ndi kuipa kwa mkulu ndi otsika kuthamanga
1. Ubwino wa seti ya jenereta yamphamvu kwambiri:
(1) Mphamvu ya jenereta ikhoza kuwonjezeka, ndipo mphamvu yaikulu ya jenereta yamagetsi yamagetsi imatha kufika zikwi zingapo, kapena makumi zikwi za kilowatts.Izi ndichifukwa choti, potulutsa mphamvu yomweyo, mphamvu yamagetsi yamagetsi yamagetsi imatha kukhala yaying'ono kwambiri kuposa yamagetsi otsika.Choncho ma windings a jenereta apamwamba amatha kugwiritsa ntchito ma diameter ang'onoang'ono a waya.Chotsatira chake, kutayika kwa mkuwa wa stator wa majenereta othamanga kwambiri kudzakhalanso kochepa kusiyana ndi majenereta otsika kwambiri.Kwa majenereta amphamvu kwambiri, mukamagwiritsa ntchito mphamvu yamagetsi otsika, malo ochulukirapo a stator amafunikira chifukwa chosowa mawaya okulirapo, zomwe zimapangitsa kuti pakatikati pa stator core ndi voliyumu yayikulu ya jenereta yonse;
(2) Kwa majenereta akuluakulu opangira mphamvu, majenereta amphamvu kwambiri amagwiritsa ntchito mphamvu zochepa ndi zida zogawira kusiyana ndi majenereta otsika kwambiri, ndipo amakhala ndi kuchepa kwa mzere wochepa, zomwe zingapulumutse kuchuluka kwa mphamvu zamagetsi.Makamaka kwa 10KV majenereta othamanga kwambiri, amatha kugwiritsa ntchito mphamvu zamagetsi mwachindunji, zomwe zingachepetse ndalama pazida zamagetsi, kugwiritsa ntchito mosavuta, komanso kuchepetsa kulephera.
2. Kuipa kwa seti ya jenereta yapamwamba kwambiri
(1) Mtengo wa ma windings a jenereta ndi wokwera kwambiri, ndipo mtengo wa zipangizo zotetezera zokhudzana nazo udzawonjezeka moyenerera;
(2) Zofunikira pa malo ogwiritsira ntchito ma jenereta ndi apamwamba kwambiri kuposa majenereta otsika;
2. Njira yolimbikitsira ma seti a jenereta
Kwa malo omwe amafunikira magetsi okwera kwambiri, kuwonjezera pa kuperekedwa kwa ma seti a jenereta okwera kwambiri, ma seti amagetsi amagetsi okhala ndi ma transfoma owonjezera angagwiritsidwenso ntchito.
1. Ubwino wa Low Voltage to High Voltage Scheme
(1) Pali zofunikira ziwiri kapena zingapo zosiyana siyana pamalo omanga, kapena mphamvu yamagetsi yamagetsi ya jenereta iyenera kusinthidwa;
(2) (Isolation transformation isolation function) Mapeto amagetsi apamwamba ndi otembenuza ngodya, ndipo njira ya waya ya magawo atatu ilibe mzere wa zero.Popanda mzere wa ziro, palibe kutengerapo kwa ziro;Kupatula ma harmonics opangidwa ndi katundu wopanda mzere kumbali yamphamvu yamagetsi kuchokera kumbali yotsika-voltage, kupangitsa mbali yotsika-voltage kukhala yoyera komanso osakhudza magwiridwe antchito a automatic voltage regulator (AVR) mkati mwa jenereta, komanso kuthetsa. mavuto osiyanasiyana obwera chifukwa cha kusamutsa kwa ziro;
(3) The Great Inertia buffering function ndiyothandiza makamaka poyambitsa ma mota akulu.Zosinthira zazikuluzikulu zimakhala ndi zinthu zambiri zamkuwa, ndipo phata lalikulu la maginito limagwira ntchito yosokoneza, kuchepetsa kukhudzidwa kwa jenereta ndikuwongolera kutsika kwamagetsi nthawi yomweyo.
2. Kuipa kwa Parallel Connection Scheme kwa Magawo Ochepa a Magetsi Opangira Magetsi
Mu seti ya jenereta ya 380-415Vac, ngati ma seti angapo a jenereta amalumikizidwa mofananira mbali yamagetsi otsika kenako amalimbikitsidwa ndi chosinthira chokwera;Malire apamwamba ndi 7500 kVA, 6000 kW.Mukadutsa malire apamwamba, izi ziyenera kuganiziridwa: -
Kuthekera kwa mabasi otsika-voltage mbali kuyenera kukhala pafupi ndi 10kA, poganizira za kuthekera kwa busbar kupirira mafunde olakwika ndi chithandizo cha kutentha mkati mwa otsika-voteji lophimba (kutentha kukwera kwa otsika-voteji lophimba chophimba);
• Kuthamanga kwa ma switch otsika-voltage (mpaka kupirira mafunde olakwika), monga mpaka 65kA ndi 100kA;
• Ndikofunikira kuwerengera ngati kuyika pafupifupi zingwe za 10000 ampere, masiwichi otsika, ndi mtengo wagawo lamagetsi otsika ndizoyenera;
3, Nkhani yokonzanso
1. Zida zikuchokera ndi magawo
Wogwiritsa: Ntchito ku Macau
● Kusungirako magetsi: UPS + 6000kVA jenereta
Total mphamvu mwadzidzidzi: 4500kVA, 3600kW
Dongosolo lamagetsi: Mphamvu yayikulu 11kV, 50Hz ndi voteji otsika 415 Vac50Hz
Mphamvu: 4 KTA50-GS8 zitsanzo / 1200kW jenereta akanema
Ntchito ya jenereta: 3 yayikulu ndi 1 yosunga zobwezeretsera, ndi 1 yosungidwa kuti ikonzedwe.Jenereta iliyonse imatha kulumikizidwa ku gridi yamagetsi kuti igwiritsidwe ntchito
Jenereta anapereka voteji: 415Vac/atatu gawo/50 m'zinthu
● Low voltage switch screen of generator set:
5000A busbar/80kA1 masekondi/magawo atatu mawaya anayi/50
Busbar ya 5000A imagawidwa m'magawo A ndi B
Gawo A la busbar limalumikizidwa ndi seti ziwiri za jenereta, imodzi ndi ziwiri
Gawo B la busbar limalumikizidwa ndi seti ziwiri za jenereta, 3 ndi 4
Kuyika kwa 5000A4 pole interconnection switch ya magawo a mabasi A ndi B
○ 4 × 2500A chosinthira mpweya → cholumikizidwa ku seti 4 za jenereta
3 × 3200A chosinthira mpweya → cholumikizidwa ndi ma thiransifoma atatu (mbali yotsika mphamvu)
● Magetsi owonjezera: 3 seti ya 2000kVA11kV/0.415kV
● High voltage switch screen of transformer: vacuum switch, 15kV600A → yolumikizidwa ndi 3 sitepe-mmwamba thiransifoma (high voteji mbali)
2. Kusanthula ndondomeko
(1) Magawo anayi a jenereta a P1500 amalumikizidwa ku gridi kuti agwiritse ntchito, pogwiritsa ntchito mayunitsi a jenereta a 3+1 molumikizana.Mosasamala kuti ndi gawo liti lomwe likufunika kusamalidwa, sizimakhudza mphamvu zamagetsi;
(2) Kukachitika kuzima kwa magetsi, seti zinayi za jenereta zidzayamba nthawi imodzi ndikugwirizanitsa masiwichi anayi a 2500A otsika-voltage ndi mawotchi atatu a 200A otsika-voltage pa mbali yotsika-voltage, magnetizing chosinthira chowonjezera ndikutseka atatu 600A mkulu. -kusintha kwamagetsi kuti apereke mphamvu kumadera osiyanasiyana;
(3) Kugawa kulikonse sikufuna kuti ATS azisinthira zokha zowonetsera kapena zipinda zodziyimira pawokha, kupulumutsa ndalama zambiri komanso chuma chamtengo wapatali;Kuthetsa vuto la kusunga zinthu zoyaka moto, utsi wa utsi, ndi phokoso lobwera chifukwa cha chipinda cha jenereta;
(4) Pakuyesa kwa tsiku ndi tsiku kwa seti ya jenereta, lamulo loyambira limaperekedwa kwa seti imodzi kapena zingapo zosankhidwa za jenereta poyerekezera vuto la mains, koma masiwichi anayi a 2500A otsika-voltage ndi ma switch atatu a 3200A otsika-voltage samatseka;Ndipo ma switch atatu a 6000A apamwamba kwambiri adalandira pulogalamu yoyeserera ndikuletsa cholumikizira kuti chitseke.Busbar ya 5000A idayatsidwa, ndipo jenereta iliyonse imalumikizidwa ndi busbar.Pambuyo poyang'anira kugwirizanitsa, 2500A low-voltage switch inatsekedwa;Pambuyo kutseka, jenereta anapereka akukumana zonse katundu mayeso.Pambuyo pa mayesowo, jenereta imayikidwa poyamba imachotsa kupanikizika koipa ndi maulendo kuti amalize mayeso (ulendo woyamba 2500A low-voltage switch -3200A low-voltage switch -600A high-voltage switch);
(5) Pamene ofesi ya magetsi ikulengeza kufunikira kwa kutsekedwa kwa magetsi, jenereta ya jenereta ikhoza kutsekedwa pamanja kuchokera kumagetsi akuluakulu pambuyo podzaza molingana ndi (4), kotero kuti jenereta ikhoza kuyatsidwa;Mpaka mphamvu ya mains itabwezeretsedwa, jenereta imagwirizanitsa ndi mphamvu ya mains pansi pa katundu.Pambuyo pa kulumikizidwa kwa gridi, seti ya jenereta imachotsedwa ndikutuluka, ndipo wogwiritsa ntchito samamva kukhudzidwa kwakanthawi kwa kuzimitsa kwamagetsi kapena kusinthana munjira yonseyi;
