Dab tsi yog qhov zoo ntawm SVG reactive fais fab nyiaj them tshuab?

SVG tuaj yeem hloov kho qhov loj thiab qhov xwm txheej (capacitive lossis inductive) ntawm nws cov zis reactive zog raws li cov yam ntxwv ntawm kev thauj khoom thiab kev ua haujlwm. Yog li ntawd, hauv essence,SVGtuaj yeem sib npaug rau lub capacitor lossis reactor uas nws loj tuaj yeem hloov kho tsis tu ncua.

SVG yog tam sim no ib qho kev siv hluav taws xob zoo tshaj plaws, nrog rau cov khoom siv them nyiaj raws li cov khoom siv hluav taws xob hloov hluav taws xob uas sawv cev rau qhov zoo tshaj plaws nyob rau hauv reactive fais fab nyiaj them txoj kev. Nws tsis siv loj - lub peev xwm capacitors lossis inductors tab sis ua tiav qhov kev hloov pauv ntawm lub zog reactive los ntawm siab - zaus hloov ntawm siab - lub zog hluav taws xob cov khoom siv hluav taws xob.

 

Txoj Cai Ua Haujlwm

Peb SVG tuaj yeem siv tau nyob rau hauv peb-theem peb- cov kab hluav taws xob thiab peb -theem plaub- xov tooj cua kom sib npaug peb-theem loads lossis txo cov kab nruab nrab. Yog li ntawd, nyob rau hauv cov cheeb tsam nyob deb nroog nrog hnyav tsis txaus thiab qee qhov chaw muaj kev lag luam.

 

Technically, SVG muaj cov txiaj ntsig hauv qab no tshaj li cov khoom siv hluav taws xob rov ua dua tshiab:

(1) Lub sij hawm teb sai dua
SVG lub sijhawm teb:<5 ms.
Ib txwm dynamic them nyiaj teb lub sij hawm: Ntau dua los yog sib npaug rau 10 ms.
SVG tuaj yeem ua tiav qhov kev sib koom ua ke los ntawm cov ntsuas capacitive reactive zog rau cov ntsuas inductive reactive zog hauv lub sijhawm luv luv. Qhov kev sib piv tsis sib xws no ua rau nws muaj peev xwm them taus rau kev cuam tshuam.

(2) Muaj peev xwm muaj zog los tiv thaiv qhov hluav taws xob Flicker
Ib txwm siv nyiaj tau zoo tuaj yeem cuam tshuam qhov hluav taws xob flicker txog li 2: 1, thaum SVG tuaj yeem ua tiav kev tawm tsam txog li 6: 1 lossis siab dua. Tsis tas li ntawd, vim SVG cov lus teb ceev heev, ua kom lub peev xwm ntawm lub cuab yeej tuaj yeem txhim kho nws lub peev xwm los txo qhov hluav taws xob flicker.

(3) Kev ua haujlwm dav dav
SVG tuaj yeem ua haujlwm nyob rau hauv qhov ntau ntawm qhov ntsuas inductive mus rau qhov ntsuas capacitive, ua rau nws qhov kev khiav hauj lwm ntau dua li lwm hom kev them nyiaj dynamic. Qhov tseem ceeb tshaj, thaum lub kaw lus qhov hluav taws xob poob qis, SVG tseem tuaj yeem tso tawm cov khoom siv hluav taws xob zoo ib yam li cov hauv qab ntsuas. Hauv qhov sib piv, lwm hom kev them nyiaj dynamic cia siab rau cov capacitors los muab lub zog reactive zog, thiab lawv cov zis reactive tam sim no yog proportional rau cov kab hluav taws xob. Qhov qis dua ntawm daim phiaj hluav taws xob, qhov qis dua qhov tso zis reactive tam sim no, yog li ua rau lawv tsis muaj peev xwm them nyiaj rau daim phiaj. Qhov no yog ib qho kev tsis txaus ntseeg ntawm lwm hom kev them nyiaj dynamic.

(4) Ntau yam kev them nyiaj yug muaj nuj nqi
Tib SVG ntaus ntawv tuaj yeem ua tiav ntau yam kev them nyiaj sib txawv:

1.Independently compensate rau load reactive zog.

2.Independently compensate rau load harmonics.

3.Independently compensate rau load imbalance.

4.Simultaneously compensate rau load reactive zog, harmonics, thiab imbalance.
Yog li, SVG muaj peev xwm them nqi zog.

(5) Ua haujlwm lim dej
Tsis tsuas yog nws tsim cov ntsiab lus tsis tshua muaj kev sib haum xeeb, tab sis nws tseem tuaj yeem them nyiaj rau kev thauj khoom sib haum xeeb thiab lub zog reactive, ua tiav cov haujlwm ntawm kev lim dej thiab ua kom muaj peev xwm ua tau ntau yam.

(6) Me Hneev taw
Raws li SVG tsis xav tau loj - lub peev xwm capacitors thiab inductors ua lub zog cia khoom, nws cov hneev taw yog feem ntau tsuas yog 50% lossis txawm me dua piv rau lwm hom kev them nyiaj dynamic ntawm tib lub peev xwm. Yog li ntawd, SVG tuav cov txiaj ntsig tseem ceeb hauv kev ua haujlwm rov qab ntawm cov chaw tsim khoom thiab cov mines.
