Cov FAQ

Ib qho kev siv lim lim haronic lim (af) yog lub zog hluav taws xob ntaus ntawv siv Txhawm rau txo Harvonic cov dej ntws hauv cov tshuab hluav taws xob. Ua zog Harmonic Lim Tso Kom Muaj Qhov sib npaug zos-tab sis-rov qab Harmonic Cov generated los ntawm cov tsis-linear loads.

Cov neeg lim dej Harters ua haujlwm los ntawm kev hnov ​​cov teeb meem zoo, thiab txhaj lub teeb liab no mus rau hauv lub zog hluav taws xob rau nruab nrab ntawm kev sib haum xeeb. Qhov no tswj xyuas lub tshuab nqus tsev ntxhua khaub ncaws ua sinusoidal tam sim no wervformal, ze rau qhov zoo tshaj plaws hauv kev siv hluav taws xob.

1.Si siv lub lim lim: txuas rau hauv cov kab nrog lub nra, them nyiaj rau voltage Harmonics.
2.Txhua Lub Lim Lim: Txuas nyob rau hauv parallel nrog lub nra, them nyiaj rau kev ua phem tam sim no.
3.Hybrid cov nquag lim dej: sib txuas ua ke thiab shunt cov lim lim rau kev ua kom zoo nkauj.

Cov lim ntim uas nquag nquag nquag tso tseg cov neeg sib haum xeeb, muab cov nyiaj them poob haujlwm zoo thiab muaj tseeb. Cov Ntxhia Lim Siv Cov Cheeb Tsam Caij Nyoog (Inductors) kom nqus cov kev sib haum xeeb tshwj xeeb, muaj cov daws teeb meem. Cov lim lim dej nquag feem ntau kim dua tab sis muaj kev ua tau zoo dua, tshwj xeeb nrog kev thauj khoom sib txawv. Passive cov ntxaij lim dej yog qhov yooj yim thiab muaj txiaj ntsig zoo rau cov teeb meem kev muaj teeb meem.

Lub tshuab hluav taws xob zoo li qub steel (SVG) yog lub zog hluav taws xob ntaus siv los tswj cov hluav taws xob reactive hauv cov hluav taws xob. Nws muab txoj kev them nyiaj sai sai rau cov kev tswj hluav taws xob thiab kev txhim kho kom zoo dua qub.

SVGs siv cov tshuab hloov hluav taws xob hluav taws xob, feem ntau voltage-sourced convers (VSCS), kom synthesize reases zog. Lawv tuaj yeem kho lawv cov txiaj ntsig sai sai los tsim lossis nqus cov hluav taws xob ua kom muaj zog raws li xav tau, tswj cov qauv hluav taws xob ruaj khov.

Thaum ob qho tib si tswj Resive Fais fab, ib qho SVG yog hom kev siv ntawm SVC tshwj xeeb uas siv cov khoom siv hluav taws xob fais fab hluav taws xob. SVC yog lub sijhawm dav dav ua kom muaj zog cuam tshuam ntau yam nyiaj ntsuab, suav nrog cov tshuaj tiv thaiv hluav taws xob (TSCS), thiab SVGs. SVGs muab cov lus teb sai thiab tswj tau yooj yim dua piv rau kev ua yeeb yam.

Ob qho tib si muab cov txhab nyiaj cuam tshuam hluav taws xob rov qab muaj cov txhab nyiaj pab pawg, thaum SVGs muab cov nyiaj them poob haujlwm zoo thiab hloov kom tau zoo. Capacitor cov tsev txhab nyiaj tau yooj yim dua thiab tsis tshua kim heev tab sis tsis muaj qhov yooj yim thiab nrawm ntawm svgs.
