Lub tswv yim ntawm lub zog zoo

Lub hwj chim zoo (PowerQuality), nruj me ntsis hais lus, cov cim tseem ceeb rau kev ntsuas lub zog zoo yog qhov voltage, zaus thiab waveform. Hauv kev nkag siab dav dav, nws hais txog cov khoom siv hluav taws xob zoo, nrog rau qhov zoo ntawm qhov hluav taws xob, qhov zoo tam sim no, lub zog hluav taws xob zoo thiab lub zog zoo. Cov teeb meem hluav taws xob zoo tuaj yeem txhais tau tias: kev sib txawv ntawm qhov hluav taws xob, tam sim no lossis zaus uas ua rau cov cuab yeej siv hluav taws xob tsis ua haujlwm lossis ua haujlwm tsis zoo, suav nrog kev sib txawv ntawm qhov sib txawv, qhov sib txawv ntawm qhov hluav taws xob, qhov hluav taws xob hloov pauv thiab flicker, peb theem tsis txaus, tam sim no lossis ib ntus overvoltage, waveform distortion (harmonics) , voltage sag, cuam tshuam, nce ib ntus thiab fais fab txuas ntxiv.
Lub tshuab hluav taws xob zoo tshaj plaws yuav tsum muab lub zog rau cov neeg siv ntawm qhov tsis tu ncua (50Hz) thiab sinusoidal waveform ntawm qhov ntsuas voltage (nominal voltage). Nyob rau hauv peb-theem AC fais fab system, qhov voltage thiab tam sim no ntawm txhua theem yuav tsum nyob rau hauv ib tug symmetrical lub xeev nrog sib npaug amplitude thiab ib theem sib txawv ntawm 120. Txij li thaum lub parameters ntawm lub system Cheebtsam (generators, transformers, kab, thiab lwm yam) yog. tsis zoo li linear los yog symmetrical, lub load zog sib txawv thiab hloov randomly, thiab vim lub imperfect tswj txhais tau tias, kev khiav hauj lwm, sab nraud cuam tshuam thiab ntau yam faults, no zoo tagnrho lub xeev tsis muaj nyob rau hauv kev muaj tiag, uas tau ua rau muaj ntau yam teeb meem nyob rau hauv lub lag luam ntawm lub hwj chim daim phiaj, cov khoom siv hluav taws xob thiab hluav taws xob noj, thiab lub tswv yim ntawm lub hwj chim zoo (Power Quality) kuj tau tsim.
Hauv kev txiav txim siab dav dav, lub hwj chim zoo yog hais txog cov khoom siv hluav taws xob zoo. Tab sis txog tam sim no, tseem muaj kev nkag siab sib txawv ntawm lub ntsiab lus ntawm lub zog zoo. Ntawm ib sab, qhov no yog vim muaj kev xav sib txawv. Piv txwv li, cov tuam txhab hluav taws xob tuaj yeem suav hais txog lub zog zoo raws li qhov tsim nyog tus nqi ntawm qhov hluav taws xob (kev sib txawv) thiab zaus (kev sib txawv), thiab siv cov txheeb cais los piav qhia tias 9% ntawm lub zog hluav taws xob ua tau raws li qhov xav tau zoo; cov neeg siv hluav taws xob feem ntau xav txog lub zog zoo li seb lub hwj huam mov rau lub nra yog qhov qub; thiab cov tuam txhab tsim khoom ntseeg hais tias tsim nyog lub zog zoo txhais tau hais tias cov khoom siv hluav taws xob muaj peev xwm ua tau raws li cov kev xav tau ntawm cov qauv tsim ntawm cov khoom siv hluav taws xob, tab sis qhov tseeb, cov kev xav tau rau cov khoom siv hluav taws xob sib txawv ntawm cov tuam txhab sib txawv thiab cov khoom sib txawv yuav nyob deb. Ntawm qhov tod tes, kev nkag siab ntawm lub zog zoo kuj raug txwv los ntawm theem ntawm kev txhim kho ntawm lub zog hluav taws xob, tshwj xeeb tshaj yog kev ua tau zoo thiab cov qauv ntawm cov khoom siv fais fab.
