Keeb kwm ntawm lub zog zoo

Qhov teeb meem ntawm lub zog zoo tau raug tsa los ntev. Nyob rau hauv thaum ntxov hnub ntawm txoj kev loj hlob ntawm lub hwj chim system, muaj pes tsawg leeg ntawm lub hwj chim load yog yooj yim, feem ntau yog tsim los ntawm linear loads xws li synchronous motors, asynchronous motors thiab ntau yam khoom siv teeb pom kev zoo. Yog li ntawd, cov ntsuas ntsuas hluav taws xob zoo kuj tseem yooj yim, feem ntau zaus offset thiab voltage offset. Txij li thaum xyoo 1980s, nrog rau kev tsim hluav taws xob hluav taws xob thev naus laus zis, cov khoom siv hluav taws xob tsis siv hluav taws xob thiab cov cuab yeej siv tau dav siv hauv kev lag luam niaj hnub no. Nyob rau tib lub sijhawm, txhawm rau daws cov teeb meem uas twb muaj lawm hauv kev txhim kho lub zog hluav taws xob nws tus kheej, DC kis tau tus mob thiab FACTS thev naus laus zis tau txuas ntxiv mus rau hauv cov ntawv thov kev tsim vaj tsev, thiab kev tswj xyuas cov motors ceev thiab cov hluav taws xob reactive zog capacitors kuj tau muab tso rau hauv. kev ua haujlwm hauv ntau qhov ntau. Kev ua haujlwm ntawm cov cuab yeej no tau ua rau qhov voltage thiab tam sim no waveform distortion nyob rau hauv daim phiaj hluav taws xob ntau dua thiab hnyav dua, thiab qib kev sib haum xeeb tau nce ntxiv. Tsis tas li ntawd, kev cuam tshuam thiab hloov pauv, xws li arc furnaces, loj dov mills, hluav taws xob locomotives, thiab lwm yam, yuav tsis tsuas yog tsim ib tug loj tus naj npawb ntawm high-order harmonics thaum lub sij hawm ua hauj lwm, tab sis kuj yuav ua rau lub hwj chim zoo teeb meem xws li voltage fluctuations, flicker. , thiab peb-theem imbalance. Ntawm qhov tod tes, nrog rau kev ua kom nrov nrov ntawm ntau yam nyuaj, meej, thiab cov khoom siv hluav taws xob zoo-rhiab, cov neeg muaj kev xav tau ntau dua thiab siab dua rau lub zog zoo, yog li lub zog zoo tau dhau los ua cov ntsiab lus kub hauv kev tshawb fawb tam sim no.
