Lub hwj chim zoo, raws li qhov taw qhia tseem ceeb rau kev ntsuas kev ua haujlwm ntawm lub zog hluav taws xob, tau pom nws cov ntsiab lus tsis tu ncua ntxiv nrog kev hloov pauv ntawm cov phiaj xwm hluav taws xob thiab cov ntawv thov scenarios. Kev faib tawm kev tshawb fawb pab kom paub meej txog cov yam ntxwv teeb meem, tsim cov tswv yim kev tswj hwm, thiab muab lub hauv paus rau kev teeb tsa tus qauv thiab kev xaiv thev naus laus zis. Tam sim no, kev lag luam feem ntau faib cov teeb meem hluav taws xob zoo raws li qhov ntev xws li kev cuam tshuam qhov xwm txheej, cov yam ntxwv spectral, ntev, thiab cov khoom cuam tshuam.
Raws li qhov xwm txheej ntawm kev cuam tshuam, teeb meem hluav taws xob zoo tuaj yeem muab faib ua ob pawg loj: khov kho- lub xeev sib txawv thiab kev cuam tshuam ib ntus. Steady-state deviations xa mus rau qhov tshwm sim uas qhov voltage lossis zaus deviates los ntawm nws cov nqi ntsuas nyob rau lub sij hawm ntev, nrog rau qhov sib txawv ntawm qhov voltage, zaus sib txawv, peb-phase imbalance, thiab harmonic distortion, feem ntau stemming los ntawm load yam ntxwv los yog system qauv asymmetry thiab nonlinearity. Cov kev cuam tshuam tsis ntev los no tshwm sim raws li lub xeev tsis xws luag nrog lub sijhawm luv luv thiab kev hloov pauv siab, xws li voltage dips, swells, luv- lub sij hawm cuam tshuam, thiab mem tes transients, feem ntau tshwm sim los ntawm luv luv -circuit faults, cov khoom loj pib-up/shutdown, los yog xob laim ntaus, ua rau muaj teeb meem loj.
Raws li cov yam ntxwv spectral, cov teeb meem tsis zoo ntawm lub zog tuaj yeem muab faib ua qhov tseem ceeb ntawm kev tsis sib haum xeeb thiab teeb meem kev sib haum xeeb. Qhov txawv txav ntawm qhov tseem ceeb zaus feem ntau yog xa mus rau qhov voltage lossis zaus amplitudes deviating los ntawm tus nqi ntsuas ntawm lub zog zaus, cuam tshuam rau cov ntsuas kev ua haujlwm ntawm cov khoom siv. Cov teeb meem kev sib raug zoo muaj xws li cov khoom sib txawv nrog cov zaus uas yog cov lej lossis cov zauv feem ntau ntawm qhov tseem ceeb zaus, pib los ntawm cov khoom tsis muaj kab xws li cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob, thiab tuaj yeem ua rau poob ntxiv, resonance, thiab kev tiv thaiv malfunctions.
Raws li lub sijhawm, kev cuam tshuam tuaj yeem faib ua plaub hom: instantaneous (milliseconds mus rau kaum milliseconds), luv -nyob (ntau pua milliseconds mus rau ob peb vib nas this), ib ntus (ntau vib nas this mus rau ib feeb), thiab pheej (ntau tshaj ib feeb). Instantaneous thiab luv luv- nyob cuam tshuam muaj feem cuam tshuam rau thaj chaw uas yuav tsum tau muaj kev txuas ntxiv, xws li kev tsim khoom thiab cov ntaub ntawv xov xwm; Kev sib txawv tsis tu ncua cuam tshuam nrog kev hloov kho ntau dua ntawm cov phiaj xwm phiaj xwm thiab qib kev lag luam nyiaj txiag.
Raws li cov khoom cuam tshuam, cov teeb meem tuaj yeem muab faib ua cov teeb meem tsis zoo, cov teeb meem zoo tam sim no, thiab cov teeb meem zoo. Voltage zoo teeb meem tsom rau kev ruaj ntseg ntawm waveforms thiab amplitudes ntawm lub hwj chim mov kawg; Cov teeb meem zoo tam sim no hais txog cov lus tawm tswv yim ntawm nonlinearity thiab impulse yam ntxwv ntawm sab load; Cov teeb meem kev ua tau zoo hais txog cov txiaj ntsig bidirectional coupling tshwm sim los ntawm qhov chaw -load kev sib cuam tshuam, uas yog qhov tseem ceeb hauv cov xwm txheej uas muaj feem ntau ntawm cov khoom siv hluav taws xob.
Nrog rau kev txhim kho cov tshuab hluav taws xob tshiab, cov kev faib hluav taws xob zoo tau nce mus rau ntau yam - kev sib koom ua ke, khaws cov kev faib cov txheej txheem ib txwm muaj thaum koom nrog cov xwm txheej hloov pauv thiab kev ntsuas cuam tshuam, muab lub hauv paus meej rau kev tswj hwm sib txawv thiab hla- kev sib koom ua ke, thiab pab txhim kho kab sib chaws resilience thiab lub zog zoo.
