Abstract
Nyob rau hauv xyoo tas los no, nrog kev loj hlob sai ntawm cov chaw zov me nyuam, cov teeb meem kev siv hluav taws xob ntawm cov chaw zov me nyuam tau dhau los ua qhov tseem ceeb. Kev tswj xyuas hluav taws xob thiab kev siv hluav taws xob thiab kev tsim qauv ntawm cov chaw zov me nyuam tau dhau los ua teeb meem kub. Tsim nyog thiab txhim khu kev qha cov ntaub ntawv chaw hluav taws xob faib cov kev daws teeb meem, yog ib txoj hauv kev tsim nyog los txhim kho lub zog ntawm cov ntaub ntawv chaw thiab txo cov khoom siv hluav taws xob. Ua ke nrog cov kev qhia tshwj xeeb, qhov zoo thiab qhov tsis zoo ntawm cov qauv qub thiab tshiab lub zog faib hluav taws xob ntawm lub chaw cov ntaub ntawv raug tshuaj xyuas, thiab cov ntaub ntawv siv tau muab rau kev tsim qauv ntawm chav tsev tshiab modular computer.

Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, tus lej, nplai, thiab lub zog ntom ntom ntawm cov ntaub ntawv chaw txuas ntxiv nce ntxiv, thiab qib kev tsim kho txuas ntxiv txhim kho. Lub zog faib hluav taws xob yog qhov tseem ceeb tshaj plaws ntawm cov ntaub ntawv chaw. Fais fab tuag los yog cov khoom siv hluav taws xob tsis zoo yuav ua rau cov neeg rau zaub mov poob haujlwm. ua rau poob. Yuav ua li cas optimize tus tsim los txhim kho kev nyab xeeb thiab kev cia siab ntawm cov ntaub ntawv chaw fais fab mov los xyuas kom meej lub uninterrupted thiab ruaj khov kev khiav hauj lwm ntawm cov ntaub ntawv hluav taws xob system tau dhau los ua ib qho teeb meem tseem ceeb rau data center designers. Piv nrog rau cov qauv siv hluav taws xob thiab kev faib tawm ib txwm muaj, txawm tias muaj kev nyab xeeb, kev lag luam thiab kev siv hluav taws xob ruaj khov dua yog qhov teeb meem uas cov neeg tsim khoom saib xyuas.
2. Lub tswv yim faib hluav taws xob thaum kawg ntawm chav ntaub ntawv
Qhov project Overview
Tag nrho cov kev tsim kho cheeb tsam ntawm ib lub chaw ntaub ntawv yog 1906.24 square meters, uas tag nrho cov kev tsim kho cheeb tsam ntawm cov ntaub ntawv chaw yog 210.6 square meters, nrog rau 1F cov ntaub ntawv chav tsev thiab 1F chav sib txuas lus. Qhov chaw ua haujlwm suav nrog chav cav loj (chav computer, chav sib txuas lus), thaj chaw tswj hwm (chaw ua haujlwm, chav siv khoom siv hauv Internet, thiab lwm yam) thiab chav pabcuam.
Txoj kev faib hluav taws xob ib txwm muaj
Lub 10kV high-voltage fais fab mov yog kos los ntawm ob qhov sib txawv substation mains, thiab cov high-voltage thiab low-voltage tsis txuas. Qhov thib peb fais fab mov yog kos los ntawm lub tshuab hluav taws xob diesel ntawm lub chaw fais fab. Lub ntsiab thaub qab fais fab mov thiab lub tshuab hluav taws xob hluav taws xob hloov pauv ntawm qhov hluav taws xob ntawm lub tshuab hluav taws xob kom ntseeg tau tias lub zog siv ntawm cov ntaub ntawv chaw. Cov cuab yeej siv hluav taws xob ntseeg tau. Xav txog tias lub peev xwm ntawm ib lub tshuab hluav taws xob tsawg dua 2500kW, thiab tus naj npawb ntawm cov tshuab hluav taws xob tsis tau mus txog ntau dua 10, 0.4kV low-voltage generator teeb raug xaiv. Qhov nruab nrab nruab nrab ntawm 0.4kV generator teeb yuav tsum ncaj qha hauv av, thiab cov conductors txuas ntawm lub hnub qub ntsiab lus ntawm lub tshuab hluav taws xob yuav tsum tau insulated. Tag nrho ntawm 2 teeb ntawm 400kVA UPS tshuab tau teeb tsa hauv qhov chaw cov ntaub ntawv los tsim 2N qhov kev ua txhaum cai. Lub dual-circuit thiab dual-tso tawm txee tuaj yeem muab lub zog rau cov khoom siv hluav taws xob cov ntaub ntawv thiab cov chaw ua haujlwm nyob hauv cov ntaub ntawv chaw. Lub roj teeb ntawm UPS system tuaj yeem muab lub zog txuas ntxiv rau 15 feeb rau txhua qib ① loads. Ib tus neeg rau zaub mov thauj khoom ntawm cov ntaub ntawv chaw yog suav tias yog 3kW, thiab qhov siab tshaj plaws load tsis tshaj 4kW. Txhawm rau kom tsis txhob muaj qhov tsis ua haujlwm ntawm cov ntaub ntawv chaw UPS thaum lub sijhawm hloov hluav taws xob los cuam tshuam rau kev ua haujlwm ib txwm muaj ntawm cov khoom tseem ceeb, hloov ATS ntawm lub mains thiab diesel generators yuav tsum yog plaub-theem hloov nrog PC-theem thiab nruab nrab kab sib tshooj. hloov.
Tshiab fais fab mov thiab faib cov phiaj xwm 2
Nrog kev tsim kho thev naus laus zis thiab kev tawm tswv yim ntawm lub tswv yim ntawm kev txuag hluav taws xob ntsuab, lub koom haum TGG thoob ntiaj teb tau thov PUE, ib qho kev ntsuas ntawm lub zog ua haujlwm ntawm cov ntaub ntawv chaw. PUE yog qhov piv ntawm tag nrho cov zog siv los ntawm cov ntaub ntawv chaw rau lub zog siv los ntawm IT loads, thiab yog qhov rov qab ntawm DCIE. PUE=kev siv hluav taws xob ntawm tag nrho cov khoom siv hauv cov ntaub ntawv chaw / lub zog siv ntawm IT cov cuab yeej, PUE yog qhov piv, qhov ntsuas yog 2, ze rau 1, qhov zoo dua qhov kev siv hluav taws xob ntau dua, qhov siab dua cov qib ntsuab ntawm ib data center.
Los ntawm kev txheeb xyuas cov ntaub ntawv ntau, nws tau txiav txim siab tias qhov hluav taws xob hluav taws xob ncaj qha tam sim no (HVDC) lub zog hluav taws xob thiab cov khoom xa tawm, AC-DC kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob thiab kev faib tawm, thiab UPS ntxiv rau HVDC muaj kev ua haujlwm ntau dua, uas tuaj yeem ua haujlwm tau zoo. txhim kho lub zog-txuag Performance index ntawm cov ntaub ntawv chaw.
3. Kev sib piv ntawm cov khoom siv hluav taws xob tshiab thiab qub thiab cov kev daws teeb meem kev faib tawm
Qhov tso zis ntawm UPS fais fab mov system yog lub zog zaus, thiab lub lim tsis loj, thiab HVDC yog cov lim dej ntau zaus thiab nyob hauv thaj chaw me me. Lub roj teeb ntawm UPS yog nyob rau hauv qhov kawg input. Yog tias UPS nws tus kheej ua tsis tiav, lub load tseem yuav poob lub zog; thaum lub roj teeb ntawm HVDC nyob rau qhov kawg tso zis. Txawm hais tias HVDC nws tus kheej tsis ua haujlwm, lub roj teeb tseem tuaj yeem muab lub zog rau lub nra kom ntseeg tau tias lub zog tsis cuam tshuam. UPS fais fab mov system muaj kev sib txuas nruab nrab ntau dua li HVDC fais fab mov. Lub roj teeb HVDC txuas ncaj qha rau lub tsheb npav, tshem tawm qhov xav tau ntawm qhov txuas inverter, thiab txhua qhov sib txuas nruab nrab ntawm qhov sib txuas yuav txo qhov kev hloov pauv hloov pauv, ua rau muaj zog siv zog ntxiv.
4. Acrelcov kev daws teeb meem rau HVDC cov kev daws teeb meem
Acrel's AMC16Z series DC fais fab faib saib xyuas cov cuab yeej yog cov cuab yeej ntsuas tshwj xeeb uas tsim los rau cov ntaub ntawv chaw server tswj fais fab. Cov cuab yeej siv tau yooj yim hauv kev tsim, thiab tuaj yeem saib xyuas txhua qhov hluav taws xob tsis muaj hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab hluav taws xob ntes cov xwm txheej ntawm A ntxiv rau B ob kab nkag thiab 192 cov kab tawm hauv lub sijhawm. Lub tswb ntsuas ntawm txhua qhov ntsuas ntsuas tuaj yeem teeb tsa ntawm nws tus kheej. Qhov kev txwv tsis pub tam sim ntawd ua rau lub suab nrov thiab lub teeb ceeb toom, thiab tuaj yeem nruab nrog lub ntsuas hluav taws xob ntsuas hluav taws xob, uas tuaj yeem kuaj xyuas cov xwm txheej rwb thaiv tsev ntawm DC system busbar thiab ceg Circuit Court rau kev saib xyuas thiab kev tswj xyuas hauv online, thiab ua tiav qib siab. ntawm kev koom ua ke ntawm kev soj ntsuam voj nyob rau hauv lub ntim ntawm cov tsoos ntsuas.
