Cov xwm txheej tsim qauv
Cov xwm txheej fais fab
Raws li lub zog hluav taws xob ntawm qhov project, peb lub tuam txhab xav kom nruab 18 MW cov roj generator teeb tsa+6 pawg ntawm cov booster thiab transformer skid (hom thawv, kom txhawb nqa mus rau 10 kV) + 1 pawg ntawm 10 kV sub-section post + 1 pawg ntawm step-down transformer skid. Los ntawm kev pub 18 pawg ntawm 1MWgas generator teeb tsa rau 6 lub thawv hom transformer skids, qhov hluav taws xob 400 V raug txhawb nqa mus rau 10 kV thiab tom qab ntawd sib sau ua ke rau 10 kV sub-section post, thiab cov sub-section post muab hluav taws xob rau lub tshuab cua txias compressor. Tib lub sijhawm, ib feem ntawm lub zog hluav taws xob raug tso tawm mus rau step-down transformer skid, 400V hluav taws xob raug faib los ntawm step-down transformer skid.
Raws li qhov tseeb fais fab load ntawm qhov project, 1 ~ 2 teeb tsa ntawm 1MW roj generator teeb tsa （kuj paub tias yog 1000kw roj genset) tuaj yeem kaw tau, uas tuaj yeem hloov pauv rau kev siv hauv kev saib xyuas lub tshuab hluav taws xob tom qabIb pawg ntawm cov chaw tswj chaw taws teeb pom kev zoo raug pom zoo rau qhov project, uas tuaj yeem saib xyuas kev ua haujlwm tshwj xeeb ntawm lub tshuab hluav taws xob hauv chav tswj hwm hauv nruab nrab. Cov pa roj flue ntawm cov tshuab hluav taws xob roj siv rau kev siv cua sov pov tseg, thiab chav tsev 1MW muaj DN300 flue gas header thiab flange.
Ib qho khoom siv hluav taws xob siab uas tus neeg siv muab yog 10KV ± 5% 50HZ ± 0.5HZ, peb theem peb-xaim, thiab qhov nruab nrab tsis tau grounded. Kev faus ncaj qha ntawm cov xov hlau siab-voltage armored tau qhia.
Kev tsim qauv
Tog B yog lub luag haujlwm rau kev tsim qauv ntawm 10KV / 0.4KV substation thiab lub zog muab thiab faib khoom ntawm lub Hoobkas liquefaction (nrog lub taub hau txais hluav taws xob ntawm 10KV lub txee nkag los ua ciam teb), lub luag haujlwm rau kev tsim cov duab hluav taws xob siab thiab qis, cov duab hluav taws xob tswj hwm, thiab daim duab Terminal, daim duab qhia txog cov khoom siv hluav taws xob siab thiab qis, thiab lub thawv ua haujlwm hauv zos (kab) tsim. Kev faib hluav taws xob ntawm Utility ntawm tag nrho cov nroj tsuag, kev muab hluav taws xob ntawm lub twj tso kua mis hluav taws xob tseem ceeb ntawm lub kaw lus tiv thaiv hluav taws, teeb pom kev zoo rau pej xeem ntawm tag nrho cov nroj tsuag, lub tsev teeb pom kev zoo, kev muab hluav taws xob thaum muaj xwm txheej ceev ntawm cov tshuab hluav taws xob diesel, thiab cov thawv faib khoom (txee) tsis nyob hauv qhov ntau thiab tsawg ntawm kev tsim qauv no.
Cov ntsiab cai tsim thiab xaiv
(1) Cov khoom siv tswj hluav taws xob ntawm lub Hoobkas ua kua dej no yuav tsum siv zog ua kom ntseeg tau, muaj kev nyab xeeb, siab heev thiab yooj yim rau kev ua haujlwm ntawm qhov kev ua tau raws li cov qauv tsim thiab cov txheej txheem xav tau.
(2) Kev tswj, kev ntsuas, kev tiv thaiv thiab lub teeb liab ntawm txhua lub cev muaj zog thiab cov khoom siv hluav taws xob yuav tsum tau teeb tsa raws li cov cai hauv tebchaws.
(3) Lub kaw lus 0.4KV hauv lub Hoobkas yog tsim los ua ob lub voj voog.
(4) Txhua yam khoom siv hluav taws xob ua haujlwm tau nruab nrog cov thawv tswj kev ua haujlwm hauv zos (txee). Qib tiv thaiv kev tawg ntawm cov khoom siv tswj hluav taws xob hauv zos hauv thaj chaw tiv thaiv kev tawg yog tsim raws li DⅡBT4, thiab nws qib tiv thaiv yog IP65; qib tiv thaiv sab nraum zoov ntawm cov khoom siv tswj hluav taws xob hauv thaj chaw tsis tawg yog IP54 Tsim, qib tiv thaiv ntawm cov khoom siv tswj hluav taws xob sab hauv tsev yog tsim raws li IP30.
(5) Thaum lub cev muaj zog siab thiab qis pib, lub zog hluav taws xob yuav tsum ua tau raws li tsis tsawg dua 85% ntawm qhov ntsuas hluav taws xob. Vim li no, cov cev muaj zog qis nrog lub zog ntsuas ntawm 75KW thiab siab dua yuav tsum pib nrog lub tshuab pib mos; lub cev muaj zog tseem ceeb ntawm lub tshuab cua txias compressor txais yuav lub zog hluav taws xob siab ntawm lub xeev khov kho mos pib.
(6) Lub kaw lus high-voltage siv lub microcomputer integrated protection device los ua kom tiav cov haujlwm xws li relay protection thiab metering.
(7) Kev ua haujlwm, kev tiv thaiv thiab lub zog teeb liab ntawm lub tshuab hloov pauv hluav taws xob siab siv lub zog DC ntawm DC220V, uas los ntawm lub roj teeb kua qaub-acid DC uas tsis tas yuav saib xyuas, thiab lub zog DC tau sib koom nrog 10KV system.
(8) Qhov xwm txheej ua haujlwm ntawm cov khoom siv hluav taws xob ntawm tag nrho cov khoom siv liquefaction thiab lub teeb liab tam sim no ntawm lub cev muaj zog ntawm 30KW thiab siab dua nkag mus rau hauv DCS system rau kev tso saib, thiab txhua yam khoom siv hluav taws xob ntawm cov khoom siv txheej txheem tuaj yeem pib thiab nres ntawm DCS hauv chav tswj hwm hauv nruab nrab, thiab kuj tuaj yeem pib thiab nres hauv zos. Cov nyees khawm nres thaum muaj xwm txheej ceev rau cov compressors refrigerant, cov roj compressors pub, cov twj tso kua dej ncig, thiab lwm yam. Tau teeb tsa hauv chav tswj hwm hauv nruab nrab.
(9) Lub microcomputer kev tiv thaiv cov cuab yeej ntawm lub nruab nrab voltage system tau faib thiab ntsia rau ntawm txhua lub txee hloov pauv, thiab lub microcomputer keeb kwm yav dhau los saib xyuas system tau teeb tsa. Lub 10KV system keeb kwm yav dhau los saib xyuas system tau sib koom nrog 35KV keeb kwm yav dhau los saib xyuas system, thiab tsis tas yuav teeb tsa sib cais. Paub txog kev saib xyuas cov kev siv hluav taws xob ntawm cov nroj tsuag liquefaction, kev saib xyuas zoo ntawm lub zog fais fab grid, kev tswj hwm chaw taws teeb ntawm cov khoom siv, kev ntsuas thiab kev ceeb toom ua haujlwm, kev tswj hwm daim ntawv qhia, kev tshuaj xyuas qhov sib txawv, kev suav txheeb, thiab kev sau txhua yam hluav taws xob ntawm cov nroj tsuag liquefaction.
(10) Lub kaw lus 10KV siab-voltage yog nruab nrog lub cuab yeej them rov qab dynamic reactive power centralized compensation los ua cov khoom siv hluav taws xob reactive rau cov khoom siv hluav taws xob siab. Tom qab them rov qab, lub zog fais fab ntawm lub tsheb npav yog ntau dua 0.95. Lub kaw lus qis-voltage yog nruab nrog lub cuab yeej hloov pauv reactive fais fab tsis sib cuag los ua cov khoom siv hluav taws xob reactive ntawm 380V lub tsheb npav. Tom qab them rov qab, lub zog fais fab ntawm lub tsheb npav yog ntau dua 0.95.
