Kev lag luam IT kev lag luam yog cov neeg siv khoom loj tshaj plaws ntawm cov khoom siv hluav taws xob tsis cuam tshuam (UPS), siv kwv yees li 75% ntawm tag nrho UPS tsim. Kev muag khoom thoob ntiaj teb txhua xyoo ntawm UPS cov cuab yeej hauv txhua hom ntawm cov chaw khaws ntaub ntawv, suav nrog kev lag luam, kev lag luam thiab ultra-loj, yog $ 3 nphom. Nyob rau tib lub sijhawm, kev muag khoom txhua xyoo ntawm UPS cov cuab yeej hauv cov chaw khaws ntaub ntawv tau nce mus txog 10% thiab nws zoo li qhov no tsis yog qhov txwv.
Cov chaw khaws ntaub ntawv tau loj dua thiab loj dua thiab qhov no ua rau muaj kev sib tw tshiab rau cov khoom siv hluav taws xob. Thaum muaj kev sib cav ntev txog qhov twg UPSs zoo li qub yog qhov zoo tshaj rau UPSs dynamic thiab vice versa, muaj ib yam uas feem ntau engineers yuav pom zoo rau - tias lub zog siab dua, cov tshuab hluav taws xob tsim nyog rau kev ua hauj lwm nrog nws: generators. tsim hluav taws xob hauv cov chaw tsim hluav taws xob.
Tag nrho cov dynamic UPSs siv lub tshuab hluav taws xob, txawm li cas los xij lawv yog cov qauv sib txawv thiab yeej txawv ntawm cov yam ntxwv thiab kev ua haujlwm. Ib qho piv txwv zoo li UPS yog qhov kev sib txuas ntawm cov tshuab hluav taws xob siv hluav taws xob, lub tshuab hluav taws xob diesel teb UPS (DRIBP). Txawm li cas los xij, nyob rau hauv lub ntiaj teb kev xyaum ntawm lub tsev cov ntaub ntawv chaw, qhov kev sib tw tiag tiag yog ntawm static UPS thiab lwm yam dynamic UPS technology - teb UPS, uas yog ib tug ua ke ntawm ib tug hluav taws xob tshuab uas generates ib tug sinusoidal voltage ntawm ntuj daim ntawv thiab lub hwj chim electronics. Xws li UPSs teb yog hluav taws xob txuas nrog lub zog cia khoom, uas tuaj yeem yog roj teeb lossis flywheels.
Kev nce qib niaj hnub hauv kev tswj hwm thev naus laus zis, kev ntseeg siab, kev ua haujlwm zoo thiab lub zog ntom ntom, nrog rau cov nqi qis dua ntawm UPS lub zog, yog cov yam ntxwv uas tsis yog tshwj xeeb rau UPS zoo li qub. Tsis ntev los no tau tshaj tawm Piller UB-V series yog qhov tsim nyog lwm txoj hauv kev.
Cia peb saib qee yam ntawm cov txheej txheem tseem ceeb rau kev ntsuam xyuas thiab xaiv UPS system rau lub chaw loj cov ntaub ntawv niaj hnub nyob rau hauv cov ntsiab lus ntawm cov thev naus laus zis zoo li yog qhov nyiam.
1. Cov nqi peev
Nws yog qhov tseeb tias UPSs zoo li qub tuaj yeem muab tus nqi qis dua ib kW rau cov tshuab UPS me, tab sis qhov kom zoo dua evaporates sai thaum nws los txog rau lub tshuab hluav taws xob siab. Lub tswv yim modular uas zoo li qub UPS cov tuam txhab lag luam inevitably yuav tsum tau txais kev hloov pauv nyob ib puag ncig ntawm kev sib txuas ntawm ntau lub zog qis UPSs, xws li 1kW qhov loj me qhia hauv qhov piv txwv hauv qab no. Txoj hauv kev no tso cai rau kom ua tiav qhov yuav tsum tau muaj lub zog tso zis, tab sis vim yog qhov nyuaj ntawm ntau cov ntsiab lus rov ua dua, nws poob 250-20% tus nqi kom zoo dua piv rau tus nqi ntawm kev daws teeb meem raws li UPS rotary. Tsis tas li ntawd, txawm tias qhov kev sib txuas ntawm cov modules no muaj kev txwv rau cov naj npawb ntawm cov chav nyob hauv ib qho UPS, tom qab ntawd cov txheej txheem sib xyaw ua ke lawv tus kheej yuav tsum tau sib npaug, uas ua rau tus nqi ntawm kev daws teeb meem ntxiv vim muaj cov hloov pauv thiab cov cables ntxiv.
Tab. 1. Kev daws piv txwv rau 48MW IT load. Qhov loj dua ntawm UB-V monoblocs txuag lub sijhawm thiab nyiaj txiag.
2. Kev ntseeg tau
Nyob rau hauv xyoo tas los no, cov chaw zov me nyuam tau dhau los ua cov lag luam muag khoom ntau dua, thaum muaj kev ntseeg tau nce ntxiv rau kev tso cai. Hauv qhov no, kev ntshai loj zuj zus tias qhov no yuav ua rau muaj teeb meem yav tom ntej. Vim tias cov tswv lag luam tsom rau qhov kev ua txhaum siab tshaj plaws (tus naj npawb ntawm 9) thiab nws tau xav tias qhov tsis zoo ntawm UPS thev naus laus zis zoo tshaj plaws los ntawm lub sijhawm luv luv los kho (MTTR) los ntawm kev muaj peev xwm sai thiab kub-swap UPS modules. Tab sis qhov kev sib cav no tuaj yeem ua rau tus kheej puas tsuaj. Qhov ntau modules koom nrog, qhov ntau dua qhov tshwm sim ntawm kev ua tsis tiav thiab, qhov tseem ceeb dua, qhov kev pheej hmoo siab dua uas qhov kev ua tsis tiav yuav ua rau poob ntawm kev thauj khoom tag nrho. Nws yog qhov zoo dua kom tsis muaj kev sib tsoo txhua.
Ib qho piv txwv ntawm kev vam khom ntawm cov khoom siv tsis ua haujlwm ntawm tus nqi ntawm lub sijhawm tsis ua haujlwm (MTBF) thaum lub sijhawm ua haujlwm ib txwm muaj nyob hauv daim duab. 1 thiab cov kev suav suav.
Rice. 1. Kev vam khom ntawm cov khoom siv tsis ua haujlwm ntawm MTBF index.
Qhov tshwm sim ntawm cov khoom siv tsis ua haujlwm Q(t) thaum lub sijhawm ua haujlwm ib txwm muaj, hauv ntu (II) ntawm daim duab ntawm qhov qub tsis ua haujlwm nkhaus, tau piav qhia zoo heev los ntawm txoj cai exponential ntawm kev faib tawm ntawm cov khoom sib txawv Q(t) = e-(Ξ»x t) ), qhov twg Ξ» = 1 / MTBF yog qhov kev siv tsis ua haujlwm, thiab t yog lub sijhawm ua haujlwm hauv cov xuab moos. Raws li, tom qab lub sijhawm t hauv lub xeev tsis muaj teeb meem yuav muaj N(t) kev teeb tsa los ntawm thawj tus lej ntawm txhua qhov kev teeb tsa N(0): N(t) = Q(t) * N(0).
Qhov nruab nrab MTBF ntawm static UPSs yog 200.000 teev, thaum MTBF ntawm rotary UPSs ntawm UB-V Piller series yog 1.300.000 teev. Kev suav qhia tau hais tias dhau 10 xyoo ntawm kev ua haujlwm, 36% ntawm UPS zoo li qub yuav nyob rau hauv kev sib tsoo, thiab tsuas yog 7% ntawm rotary UPSs. Muab rau hauv tus lej sib txawv ntawm UPS cov cuab yeej (Table 1), qhov no txhais tau tias 86 qhov ua tsis tiav ntawm 240 static UPS modules thiab 2 tsis ua haujlwm ntawm 20 Piller rotary UPSs, hauv tib lub chaw cov ntaub ntawv nrog 48MW IT payload tshaj 10 xyoo ntawm kev ua haujlwm.
Cov kev paub ntawm kev khiav hauj lwm zoo li qub UPSs ntawm cov chaw zov me nyuam cov ntaub ntawv hauv Russia thiab hauv ntiaj teb tau lees paub qhov kev ntseeg tau ntawm cov kev suav sau saum toj no, raws li cov txheeb cais ntawm kev ua tsis tiav thiab kev kho tshiab muaj los ntawm cov chaw qhib.
Tag nrho cov Piller teb UPSs, thiab tshwj xeeb tshaj yog cov UB-V series, siv lub tshuab hluav taws xob los tsim cov sine yoj ntshiab thiab tsis txhob siv lub hwj chim capacitors thiab IGBT transistors, uas yog feem ntau ua rau tsis ua hauj lwm nyob rau hauv tag nrho cov static UPSs. Ntxiv mus, ib qho zoo li qub UPS yog ib feem ntawm cov khoom siv hluav taws xob. Complexity txo kev ntseeg tau. UB-V rotary UPSs muaj cov khoom siv tsawg dua thiab tsim kom muaj zog ntau dua (lub tshuab hluav taws xob) kom txhim kho kev ntseeg tau.
3. Kev siv hluav taws xob zoo
Niaj hnub nimno zoo li qub UPSs muaj qhov zoo dua hauv online (lossis "ib txwm" hom) kev siv hluav taws xob ntau dua li lawv cov thawj coj. Raws li txoj cai, nrog cov txiaj ntsig zoo tshaj plaws ntawm qib 96,3%. Cov duab siab dua feem ntau tau muab, tab sis qhov no tsuas yog ua tiav thaum UPS zoo li qub ua haujlwm, hloov ntawm online thiab lwm hom (xws li ECO-hom). Txawm li cas los xij, thaum siv lwm hom kev txuag hluav taws xob, lub load yog ua los ntawm lwm lub network yam tsis muaj kev tiv thaiv. Vim li no, hauv kev xyaum hauv cov chaw zov me nyuam feem ntau tsuas yog siv hom online.
Piller UB-V series ntawm rotary UPSs tsis hloov lub xeev thaum lub sijhawm ua haujlwm li qub thaum tseem muab txog 98% kev ua haujlwm hauv online ntawm 100% load thiab 97% ntawm 50% load.
Qhov sib txawv ntawm kev siv hluav taws xob no tso cai rau koj kom tau txais kev txuag hluav taws xob tseem ceeb thaum ua haujlwm (Table 2).

4. Chaw nyob
Lub hom phiaj tseem ceeb ntawm UPSs tau dhau los ua qhov sib txuam nrog kev hloov pauv mus rau IGBT thev naus laus zis thiab tshem tawm cov hloov pauv. Txawm li cas los xij, txawm hais tias qhov xwm txheej no, UB-V series rotary UPSs muab qhov nce ntawm 20% lossis ntau dua ntawm qhov chaw nyob hauv ib chav tsev ntawm lub zog. Qhov txiaj ntsig ntawm qhov chaw txuag tau tuaj yeem siv ob qho tib si los ua kom muaj peev xwm ntawm lub zog ntawm qhov chaw, thiab ua kom "dawb", muaj txiaj ntsig, qhov chaw ntawm lub tsev kom haum rau cov servers ntxiv.

5. Muaj
Ib qho ntawm cov cim tseem ceeb ntawm qhov chaw zoo tsim, tsim thiab ua haujlwm cov ntaub ntawv yog nws qhov kev ua txhaum siab rau qhov sib piv. Thaum 100% uptime yog ib txwm lub hom phiaj, cov ntaub ntawv qhia tias ntau tshaj 30% ntawm lub ntiaj teb no cov ntaub ntawv chaw zov me nyuam muaj tsawg kawg yog ib tug unplanned outage nyob rau hauv ib xyoos. Ntau ntawm cov no yog tshwm sim los ntawm tib neeg kev ua yuam kev, tab sis lub zog infrastructure kuj plays lub luag haujlwm tseem ceeb. UB-V series siv ntau xyoo ntawm kev pov thawj Piller monobloc teb UPS thev naus laus zis uas yog qhov zoo tshaj plaws hauv kev ntseeg siab rau lwm yam thev naus laus zis. Dab tsi ntxiv, UB-V UPS nws tus kheej hauv cov chaw khaws ntaub ntawv nrog ib puag ncig tswj kom zoo tsis tas yuav raug kaw txhua xyoo rau kev saib xyuas.
6. Yooj yim
Feem ntau, cov ntaub ntawv chaw IT systems tau hloov kho thiab kho dua tshiab hauv 3-5 xyoos. Yog li ntawd, lub zog thiab cua txias infrastructures yuav tsum yoog raws li qhov no thiab muaj txaus rau yav tom ntej. Ob qho tib si zoo li qub UPS thiab UB-V UPS tuaj yeem teeb tsa hauv ntau txoj hauv kev.
Txawm li cas los xij, muaj pes tsawg leeg ntawm cov kev daws teeb meem raws li yav tas los yog dav dua, thiab feem ntau hais lus, vim qhov no dhau ntawm qhov kev nthuav dav ntawm tsab xov xwm no, nws ua rau nws muaj peev xwm siv cov tshuab hluav taws xob tsis cuam tshuam ntawm qhov nruab nrab ntawm 6-30 kV, ua haujlwm. ntawm cov tes hauj lwm nrog cov khoom siv txuas ntxiv dua tshiab thiab lwm tiam, tsim kom muaj txiaj ntsig zoo, txhim khu kev ntseeg siab, Tier IV UI raws IP Bus systems hauv N + 1 teeb tsa.
Raws li qhov xaus, ntau cov lus xaus tuaj yeem kos. Cov chaw zov me nyuam ntau cov ntaub ntawv hloov zuj zus, qhov nyuaj dua txoj hauj lwm ntawm optimizing lawv ua thaum nws yog ib qho tsim nyog los tswj cov kev ntsuas nyiaj txiag ib txhij, kev ntseeg siab, lub koob npe nrov thiab txo qis ntawm ib puag ncig. Static UPSs tau ua thiab yuav txuas ntxiv siv rau hauv cov chaw khaws ntaub ntawv yav tom ntej. Txawm li cas los xij, nws tseem tsis tau lees paub tias muaj lwm txoj hauv kev uas twb muaj lawm hauv kev siv hluav taws xob hluav taws xob uas muaj qhov zoo ntawm "zoo qub statics".
