Technical Advantages ntawm SVG Reactive Power Compensation Devices

I. Teb ceev ceev thiab muaj zog Dynamic Regulation muaj peev xwm

SVG siv cov khoom siv hluav taws xob tswj hluav taws xob tag nrho (xws li IGBTs) rau lub sijhawm tiag tiag - lub sijhawm reactive zog tswj, nrog lub sij hawm teb tsawg dua 5 ms, sai dua li ntau pua milliseconds ntawm ncua sij hawm cuam tshuam nrog kev hloov pauv hloov pauv ib txwm muaj.

Qhov no txhais tau hais tias thaum muaj kev hloov pauv tam sim ntawd hauv daim phiaj thauj khoom (xws li, thaum lub sijhawm pib ntawm cov motors loj lossis kev ua haujlwm ntawm cov zaus hloov pauv), SVG tuaj yeem muab tau sai lossis nqus tau lub zog, tswj qhov system voltage stability thiab txo qhov voltage flicker.

 

II.Kev hloov kho tas mus li rau kev them nyiaj tshwj xeeb

Cov khoom siv them nyiaj ib txwm siv feem ntau siv "stepwise" hloov, ua rau cov nyiaj them poob haujlwm tsis tu ncua thiab muaj peev xwm nyob rau hauv - nyiaj pab los yog tshaj - cov nyiaj them poob haujlwm. Hauv qhov sib piv, SVG siv PWM tswj thev naus laus zis kom ua tiav kev hloov kho txuas ntxiv ntawm lub zog reactive, ua kom lub zog muaj zog kom tswj tau qhov tseeb saum 0.99.

Txoj kev tswj xyuas kom zoo no ua kom muaj txiaj ntsig zoo rau kev ua haujlwm raws li ntau yam kev ua haujlwm, txhim kho kev siv hluav taws xob zoo.

 

III.Harmonic Suppression Function

Thaum lub sijhawm ua haujlwm, SVG tuaj yeem tiv thaiv kev sib raug zoo tam sim no los ntawm nws tus choj inverter. Qee cov qauv txawm koom ua ke siv lub zog lim dej ua haujlwm (APF + SVG ua ke), tshem tawm 5th, 7th, thiab siab dua - xaj kev sib haum xeeb hauv daim phiaj.

Qhov no tsis tsuas yog txhim kho qhov hluav taws xob waveform zoo tab sis kuj tseem tiv thaiv cov cuab yeej xws li transformers thiab capacitors los ntawm thermal teebmeem ntawm harmonics.

 

IV.Bidirectional Compensation, Tau tshaj Inductive thiab Capacitive Loads

Cov cuab yeej siv hluav taws xob siv hluav taws xob tuaj yeem tsuas yog muab lub zog reactive xav tau los ntawm inductive loads, whereas SVG tuaj yeem ua cov kev cai bidirectional -ob leeg muab lub zog reactive (paub rau inductive loads) thiab absorbing reactive zog (compensating rau capacitive loads).

Qhov kev hloov pauv no tso cai rau SVG ua haujlwm ruaj khov hauv ntau qhov xwm txheej nyuaj, xws li kev thauj khoom ib puag ncig hauv cov hlau, tshuaj, chaw nres nkoj, thiab hluav taws xob tsheb them chaw nres tsheb.

 

V. Modular Tsim kom yooj yim nthuav dav thiab tu

Cov khoom siv SVG niaj hnub no feem ntau siv cov qauv tsim qauv, txhawb nqa ntau -unit parallel ua haujlwm. Cov neeg siv tuaj yeem ua kom muaj peev xwm nthuav dav raws li - qhov hloov pauv ntawm qhov chaw thauj khoom, thiab kub- hloov pauv hloov tau thaum lub sijhawm tu ua rau txhim kho kev ntseeg tau thiab kev ruaj ntseg.
