1. Core Voltage Stabilization (Pib Muaj nuj nqi)
Ua piv txwv peb -theem voltage tso tawm los ntawm lub tshuab hluav taws xob raws li kev tawm tswv yim, thiab sab hauv piv nrog cov qauv ntsuas hluav taws xob (feem ntau 400V peb-theem lossis 230V ib zaug-theem):
(1) Tsawg voltage → AVR tsub kom lub excitation tam sim no, ntxiv dag zog rau lub rotor magnetic teb thiab kho cov zis voltage;
(2) High voltage → AVR txo qhov excitation tam sim no, ua rau cov hlau nplaum tsis muaj zog thiab ua rau lub zog poob;
Txawm hais tias tsis muaj kev thauj khoom, daim ntawv thov thauj khoom tam sim lossis tshem tawm, qhov hluav taws xob ib txwm nyob hauv qhov kev tso cai los tiv thaiv kev hloov pauv uas tuaj yeem ua rau lub teeb, lub cev muaj zog, thiab cov txee tswj.
2. Excitation thiab Voltage Build-up
Thaum lub tsev yog thawj zaug pib thiab qhov ceev tseem tsis tau mus txog qhov ntsuas tus nqi, qhov seem hlau nplaum tsis muaj zog, yog li lub tshuab hluav taws xob tsis tuaj yeem tsim hluav taws xob ntawm nws tus kheej.
Lub tshuab hluav taws xob tswj hluav taws xob muaj ib qho ua tau - nyob rau hauv excitation Circuit Court uas siv ib qho me me ntawm cov hlau nplaum seem los yog lub zog txhawb nqa los ntawm lub roj teeb los muab thawj zaug tam sim no rau lub tshav pob winding, ua rau lub tshuab hluav taws xob tsim kom muaj qhov ntsuas hluav taws xob sai.
Yog tias tsis muaj AVR lossis yog AVR puas lawm, lub tsev yuav tig tab sis tsim tsis muaj qhov hluav taws xob tso tawm.
3. Dynamic Voltage Regulation rau Load Adaptation
Thaum lub sij hawm pib lub siab - cov khoom siv fais fab (xws li lub cev muaj zog thiab cov tshuab cua compressors), muaj qhov tseem ceeb tam sim no voltage poob. Lub AVR tam sim ntawd nce qhov excitation them voltage, tiv thaiv qhov voltage ntawm collapsing tam sim ntawd thaum lub load yog thov.
Thaum lub load hnyav raug tshem tawm, nws tiv thaiv cov hluav taws xob hluav taws xob uas tuaj yeem ua rau cov khoom siv hluav taws xob puas.
4. Txhawb kev tiv thaiv muaj nuj nqi (txheej txheem ntawm txawv AVR qauv)
(1) Tsawg-frequency tiv thaiv: Thaum lub tsev ceev qis dhau lawm (tsis txaus), excitation raug txwv los tiv thaiv cov cuab yeej puas vim muaj tsawg-voltage load ua haujlwm;
(2) Kev tiv thaiv overvoltage: Tshem tawm qhov siab tshaj qhov hluav taws xob thaum lub sij hawm ua txhaum los tiv thaiv kev tawg ntawm lub tshuab hluav taws xob windings thiab cov khoom siv hluav taws xob qis.
(3) Mos excitation: maj mam nce voltage thaum pib, tsis txhob muaj kev cuam tshuam tam sim ntawd.
5. Parallel/Grid-Kev Txuas Ua Haujlwm (Dedicated AVR rau Parallel Operation)
Thaum ntau chav nyob ua haujlwm nyob rau hauv tib lub sijhawm, AVR tuaj yeem kho cov hluav taws xob reactive faib kom ntseeg tau tias muaj qhov sib npaug ntawm txhua chav nyob, tiv thaiv cov dej ntws tawm thiab zam kev sib tw hluav taws xob reactive.
6. Distinguishing Brushed/Brushless Generator AVR
(1) Brushless generator AVR: Muab lub zog rau lub exciter stator, indirectly tswj lub ntsiab generator lub magnetic teb;
(2) Brushed generator AVR: ncaj qha muab cov khoom siv hluav taws xob rau lub rotor swb nplhaib.
