Cov ntsuas hluav taws xob muaj ntau heev, tab sis koj puas tau xav tias "cov khoom siv" siv los ntsuas cov ntsuas no nws tus kheej li cas? Tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm kev siv ntau megawatt-theem ultra- chaw nres tsheb ceev ceev rau lub zog tshiab tsheb, yuav ua li cas kom tiav - lub zog ntsuas hluav taws xob ntawm lub ntsuas hluav taws xob yuav ua li cas thaum nws yuav siv 1000 kilowatt- teev hluav taws xob hauv ib teev xwb?
Puas yog cov ntsuas hluav taws xob ib txwm sim nyob rau hauv cov xwm txheej tiag tiag? Hauv kev ntsuas hluav taws xob, peb ntse siv "virtual load" thev naus laus zis los daws qhov teeb meem no.
Puas yog txhua qhov kev ntsuas hluav taws xob ntsuas tau ua tiav nrog lub "tiag" load?
Xaus: Tsis tas li. Txawm hais tias, nyob rau hauv txoj cai, tsav lub ntsuas hluav taws xob nrog lub load tiag tiag yog txoj kev sim yooj yim tshaj plaws, hauv kev xyaum, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas muaj cov hluav taws xob siab, siab tam sim no, lossis siab precision, "simulated load method" yog txoj hauv kev loj.
Rau qhov saum toj no UBS hluav taws xob megawatt ceev-chaw nres tsheb lub zog ntsuas hluav taws xob (1000V / 1000A), yog tias muaj tiag- kev ntsuas load ua tiav:
• Lub zog:P=U*I=1000V * 1000A=1,000,000W=1MW
• Kev siv hluav taws xob:Kev khiav ntawm tag nrho cov load rau ib teev yuav tsum tau siv 1000 kilowatt- teev hluav taws xob thiab yuav tsum tau ua kom txias txias.
Qhov no yog qhov tsis tshua muaj nyiaj txiag thiab nyuaj rau kev siv hauv chav kuaj lossis thaj chaw calibration. Yog li ntawd, rau ob qho tib si AC thiab DC lub zog ntsuas, "phantom load testing method" (tseem hu ua "standard meter method" lossis "power source method") yog cov txheej txheem tseem ceeb rau siab - fais fab calibration.
Kev kuaj load tiag tiag vs. simulated load kuaj: Dab tsi yog qhov txawv?
Ob txoj kev tuaj yeem muab piv rau "hnyav ib yam dab tsi":
• Kev xeem Load tiag:Qhov no yog qhov sib npaug ntawm qhov ntsuas qhov hnyav ntawm qhov paub qhov hnyav (lub cev muaj zog tiag tiag) ntawm qhov ntsuas (hluav taws xob ntsuas) kom pom seb qhov ntsuas puas yog.
• Virtual Load Test:Qhov no yog sib npaug rau simulating lub teeb liab "dag" los ntawm ib lub voj voog, qhia lub ntsuas hluav taws xob tias "tam sim no tau siv hluav taws xob," tab sis qhov tseeb, tsis muaj hluav taws xob ntau npaum li cas.
Load Verification Method
Txoj kev no siv cov khoom siv lub cev tiag tiag (xws li resistors, inductors, thiab capacitors) raws li cov khoom thauj:
• Txoj Cai:Lub ntsuas hluav taws xob tus qauv thiab lub ntsuas hluav taws xob nyob rau hauv kev sim tau txuas nrog hauv cov kab hauv tib lub sijhawm thauj khoom tiag tiag, tso cai rau lawv ua haujlwm hauv tib qhov hluav taws xob thiab tam sim no. Qhov sib txawv ntawm lawv cov kev nyeem ntawv yog muab piv nrog.
• Application Scenarios:Feem ntau siv rau qhov yooj yim ntawm - qhov chaw pov thawj, kuaj cov laus induction- hom ntsuas hluav taws xob, lossis hauv cov chaw sim me me uas tsis muaj siab - cov khoom siv hluav taws xob muaj tseeb.
Virtual Load Verification Method
Qhov no yog txoj hauv kev tseem ceeb rau kev ntsuas hluav taws xob niaj hnub, tshwj xeeb tshaj yog rau cov ntsuas hluav taws xob hluav taws xob thiab DC lub zog ntsuas hluav taws xob:
• Txoj Cai:Lub programmable fais fab qhov chaw yog siv los ntawm nws tus kheej muab voltage thiab tam sim no. Qhov hluav taws xob hluav taws xob thiab hluav taws xob tam sim no tau sib cais ntawm lub cev (qhov hluav taws xob hluav taws xob muaj qhov tsis tshua muaj tam sim no, thiab tam sim no muaj hluav taws xob tsawg heev). Cov khoom siv hluav taws xob muaj tseeb simulate ntau yam kev ua haujlwm uas yuav tsum tau ua rau kev ua haujlwm ib txwm muaj ntawm lub ntsuas hluav taws xob (xws li cov khoom siv hluav taws xob sib txawv thiab qhov sib txawv tam sim no).
• Application Scenarios:Yuav luag txhua lub chaw kuaj mob puv -kev ua pov thawj, kev tshuaj xyuas lub Hoobkas, thiab siab - qhov tseeb ntawm - qhov chaw calibration.
Kev sib piv ntawm Ob Txoj Kev Xeem
| Sib piv Dimension | Qhov tseeb Load Calibration Method | Virtual Load Calibration Method |
|---|---|---|
| Kev siv hluav taws xob | Siab heev. Yuav tsum tau hloov hluav taws xob hluav taws xob rau hauv hluav taws xob thiab hluav taws xob, uas yog lub zog- siv thiab ua rau muaj cua sov loj heev. | Tsawg heev. Tsuas yog siv lub zog me me ntawm cov cuab yeej nws tus kheej, lub zog -txuag thiab tus phooj ywg ib puag ncig. |
| Khoom ntim | Loj thiab hnyav. Cov dej ntws loj yuav tsum muaj cov thawv loj loj (zoo ib yam li cov hluav taws xob loj heev). | Compact thiab lub teeb yuag. Feem ntau yog tsim los ntawm cov khoom siv hluav taws xob, yooj yim los ua portable. |
| Kev kuaj qhov tseeb | Tsawg heev. Muaj kev cuam tshuam zoo heev los ntawm kev thauj khoom tivthaiv kev laus thiab kub drift, nyuaj kho. | Siab heev. Muaj peev xwm ncav cuag 0.05% lossis siab dua qhov tseeb nrog zoo linearity. |
| Kev Pabcuam Ntau | Txwv tsis pub. Yooj yim kom raug simulate me me tam sim no (piv txwv li, pib tam sim no) lossis huab cua dhau heev. | Muaj ntau yam. Tau yooj yim npog tag nrho ntau yam los ntawm kev pib tam sim no (0.4% Ib) mus rau qhov siab tshaj plaws tam sim no. |
| Kev nyab xeeb | Tsawg heev. Kev tsim hluav taws xob siab tam sim no thiab luv luv - muaj kev pheej hmoo hauv Circuit Court, nrog rau kev nyab xeeb kev nyab xeeb. | Kwv tij siab. Tswj Circuit Court thiab lub zog hluav taws xob raug cais tawm, nrog cov txheej txheem tiv thaiv tiav. |
1.Vim li cas txoj kev thauj khoom virtual muaj qhov tseeb dua?
Nyob rau hauv txoj kev thauj khoom tiag tiag, yog tias lub kauj tam sim no muaj qhov tsis kam, qhov hluav taws xob poob yuav tshwm sim, ua rau muaj kev hloov pauv ntawm qhov hluav taws xob hla qhov hluav taws xob hluav taws xob, yog li qhia "qhov yuam kev ntxiv." Hauv txoj kev thauj khoom virtual, qhov hluav taws xob hluav taws xob thiab qhov hluav taws xob tam sim no muaj kev ywj pheej thiab tsis cuam tshuam rau ib leeg, yog li tsis muaj qhov yuam kev ntxiv, thiab cov txiaj ntsig kev ntsuas tau ze dua rau qhov tseeb qhov tseeb.
2.Vim li cas txoj kev thauj khoom virtual tuaj yeem ntsuas megawatt -theem fais fab?
Lub virtual load calibration ntaus ntawv (tus qauv qhov chaw) siv siab - fais fab transistors lossis IGBT modules sab hauv los hloov DC fais fab rau hauv AC waveform, lossis ua DC precision tswj. Tsis zoo li txoj kev thauj khoom tiag tiag, nws tsis tas yuav dissipate 1 MW ntawm hluav taws xob hluav taws xob raws li cua sov; Hloov chaw, los ntawm kev kaw - voj tswj, nws tuaj yeem simulate cov yam ntxwv hluav taws xob ntawm 1 MW nrog tsuas yog lub zog me me xwb.
Cov ntsiab lus
Cia peb rov qab mus rau lo lus nug thawj zaug: Puas yog cov ntsuas hluav taws xob ib txwm sim nyob rau hauv cov xwm txheej tiag tiag?
Tsis yog. Tsuas yog rau qhov tshwj xeeb ntawm - qhov chaw sim ua kom yooj yim los yog ntsuas cov ntsuas qub, kev ntsuas hluav taws xob niaj hnub (tshwj xeeb tshaj yog rau siab -voltage, siab -tam sim no DC ceev chargers) yuav luag 100% siv simulated load testing method.
Txawm hais tias txoj kev thauj khoom tiag tiag yog "qhov tseeb," nws tau maj mam phased tawm los yog tsuas yog siv los ua ib qho kev pabcuam vim muaj kev txwv ntawm kev siv zog, qhov loj me, thiab qhov tseeb.
Txoj kev simulated load siv cov cuab yeej siv hluav taws xob siab tshaj plaws kom ua tiav "cov khoom siv me me tuav cov khoom loj," kom ntseeg tau qhov tseeb ntawm lub teb chaws cov qauv ntsuas ntsuas thaum daws teeb meem kev siv hluav taws xob ntawm kev sim megawatt - theem ceev them chaw nres tsheb.
Lub sijhawm tom ntej koj pom tias lub ntsuas hluav taws xob me me ntawm lub chaw them nyiaj, nco ntsoov tias tom qab nws yog "극한 siab ntsuas" npog tag nrho cov kev ua haujlwm, simulated los ntawm cov khoom siv hluav taws xob siab -tech.
