Kev ua haujlwm ntawm qhov system
Nws txhais tau hais tias tag nrho cov Cheebtsam ntawm lub system yog nyob rau hauv lub xeev ntawm kev ua lawv cov dej num. Qhov tseem ceeb ntawm lub zog hluav taws xob yog los xyuas kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm lub zog tsim nyog thiab pheej yig rau cov neeg siv. Qhov kev tsim nyog tau txais txiaj ntsig txhais tau hais tias peb qhov tseem ceeb ntawm qhov hluav taws xob, zaus thiab sinusoidal waveform yuav tsum nyob rau hauv qhov kev teev tseg. Txawm hais tias kev npaj, tsim thiab kev siv lub zog hluav taws xob muab cov khoom tsim nyog rau kev ua tiav ntawm cov kev xav tau saum toj no, qhov kev ua tiav zaum kawg yog nyob ntawm kev ua haujlwm ntawm lub zog hluav taws xob. Kev xyaum qhia tau hais tias lub zog hluav taws xob nrog cov khoom siv zoo kuj tseem yuav ua rau muaj kev cuam tshuam loj heev vim kev ua haujlwm yuam kev. Piv txwv li, thaum Lub Xya Hli 13, 1977, lub zog hluav taws xob ntawm New York City hauv Tebchaws Meskas tau raug xob laim. Vim tias qhov tsis ua haujlwm ntawm cov cuab yeej tiv thaiv ua kom raug, tsis muaj cov ntaub ntawv ntawm lub sijhawm tiag tiag hauv qhov chaw xa khoom thiab lwm yam laj thawj, qhov kev sib tsoo tau nthuav dav, ua rau lub kaw lus kaw thiab lub nroog lub zog hluav taws xob. Qhov xwm txheej tau siv sijhawm 25 teev ua ntej thiab tom qab kev kho mob, cuam tshuam rau lub zog ntawm 9 lab tus neeg nyob hauv. Raws li qhov kev kwv yees tshaj plaws ntawm US Department of zog, qhov kev poob ncaj qha thiab tsis ncaj los ntawm qhov xwm txheej yog 350 lab US dollars. Nyob rau xyoo 1960-1970s, qhov hluav taws xob loj loj tau tshwm sim ntau zaus hauv ntiaj teb, uas ua rau tib neeg tau txais kev saib xyuas ntau dua los txhim kho kev ua haujlwm zoo ntawm lub zog hluav taws xob thiab txhim kho qib ntawm kev xa tawm automation.
Kev ua haujlwm ntawm lub zog hluav taws xob feem ntau tau piav qhia los ntawm lub xeev kev ua haujlwm, uas feem ntau muab faib ua lub xeev ib txwm muaj thiab lub xeev txawv txav. Lub xeev ib txwm muab faib ua lub xeev kev nyab xeeb thiab lub xeev ceeb toom, thiab lub xeev txawv txav tau muab faib ua lub xeev xwm txheej ceev thiab lub xeev rov qab los. Lub tshuab hluav taws xob ua haujlwm suav nrog tag nrho cov xeev no thiab lawv cov kev sib koom ua ke (Daim duab 3).
Kev hloov pauv ntawm ntau lub xeev kev ua haujlwm yuav tsum tau ua tiav los ntawm kev tswj hwm, xws li kev tiv thaiv kev tiv thaiv, kev tswj xyuas thiab kev ruaj ntseg, kev tswj kev kub ntxhov, kev tswj xyuas rov qab, thiab lwm yam. Cov no suav nrog kev tswj hwm kev ruaj ntseg.
Nyob rau ntawm qhov chaw ntawm kev ua kom lub zog zoo, muaj kev nyab xeeb thiab txhim khu kev qha, lub zog hluav taws xob yuav tsum paub txog kev lag luam kev lag luam, uas yog, txhawm rau kho qhov nkhaus ntawm cov khoom siv, txhim kho kev siv cov khoom siv, ua kom muaj nuj nqis siv ntau yam khoom siv hluav taws xob, txo cov roj siv hluav taws xob. , pabcuam kev siv hluav taws xob thiab kev lag luam poob, thiaj li tau txais txiaj ntsig zoo tshaj plaws ntawm kev lag luam.
Lub xeev muaj kev nyab xeeb txhais tau hais tias qhov zaus ntawm lub zog hluav taws xob, qhov hluav taws xob ntawm txhua qhov taw qhia thiab qhov thauj khoom ntawm txhua qhov khoom yog tag nrho nyob rau hauv qhov kev tso cai tus nqi ntau, thiab thaum lub kaw lus raug cuam tshuam vim kev hloov pauv lossis tsis ua haujlwm, nws yuav tsis tawm ntawm qhov qub. ua haujlwm xeev. Raws li tiam neeg, kev sib kis thiab kev siv hluav taws xob hluav taws xob yuav tsum sib npaug txhua lub sijhawm, thiab cov khoom siv hluav taws xob hloov pauv txhua lub sijhawm, yog li lub xeev muaj kev nyab xeeb yog qhov ua tau zoo, uas tuaj yeem tswj tau tsuas yog los ntawm kev hloov kho thiab kev tswj hwm ib txwm muaj (nrog rau zaus. thiab voltage, piv txwv li active thiab reactive hloov).
Lub xeev ceeb toom hais txog tias tag nrho cov kab ke tseem nyob hauv ntau yam kev cai tswj hwm kev nyab xeeb, tab sis kev ua haujlwm tsis ua haujlwm ntawm ib tus neeg cov khoom lossis lub network hauv zos nyob ze rau qhov pib ntawm kev nyab xeeb. Thaum muaj kev cuam tshuam, lub kaw lus yuav tawm ntawm lub xeev qub thiab nkag mus rau lub xeev xwm txheej ceev. Thaum nws nyob hauv lub xeev ceeb toom, kev tiv thaiv kev tiv thaiv yuav tsum tau ua kom nws rov qab mus rau lub xeev muaj kev nyab xeeb.
