Qhov Kev Ua Haujlwm ntawm Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob (AVR Tsis Siv Neeg Voltage Regulator) ntawm Diesel Generator Sets (Cov Tswv Yim Pom Zoo, Tsim Nyog rau Beginners)

1. Core Voltage Regulation (Primary Function)

 

Nws sau lub tshuab hluav taws xob tso zis peb-theem voltage rau kev tawm tswv yim thiab sab hauv piv nrog cov qauv ntsuas hluav taws xob (feem ntau 400V peb-theem, 230V ib zaug-theem):

 

1. Yog tias qhov hluav taws xob tsawg dhau→ AVR tsub kom lub excitation tam sim no, lub rotor lub magnetic teb muaj zog, thiab cov zis voltage nce;

 

2. Yog tias qhov hluav taws xob siab dhau→ AVR txo qhov excitation tam sim no, lub magnetic teb tsis muaj zog, thiab qhov hluav taws xob poob;

Txawm hais tias tsis muaj kev thauj khoom, kev thauj khoom sai sai, lossis kev tshem tawm tam sim ntawd, nws ib txwm khaws cov hluav taws xob nyob rau hauv qhov kev tso cai, tiv thaiv kev puas tsuaj rau lub teeb, lub cev muaj zog, thiab tswj cov khoom los ntawm qhov hluav taws xob tawg lossis poob.

 

2. Excitation Start thiab Voltage Build-up

Thaum lub tsev tau pib thawj zaug thiab qhov ceev tseem tsis tau mus txog qhov ntsuas tus nqi, qhov seem hlau nplaum tsis muaj zog, thiab lub tshuab hluav taws xob nws tus kheej tsis tuaj yeem tsim hluav taws xob. Lub tshuab hluav taws xob tswj hluav taws xob muaj tus kheej -kev tawm suab hluav taws xob uas siv me me ntawm cov hlau nplaum seem lossis roj teeb - pab lub zog los muab qhov pib tam sim no rau kev ua kom muaj zog, tso cai rau lub tshuab hluav taws xob kom ncav cuag qhov ntsuas hluav taws xob sai.

 

Yog tsis muaj AVR lossis yog AVR puas lawm, chav tsev yuav tig tab sis tsis muaj qhov hluav taws xob yuav tawm.

 

3. Ua kom haum rau Load rau Dynamic Voltage Regulation

Thaum siab - cov khoom siv fais fab pib (lub cev muaj zog, cua compressors), muaj qhov poob siab tam sim ntawd. AVR yuav tam sim ntawd nce qhov excitation them voltage kom qhov voltage tsis vau tam sim ntawd thaum lub load yog thov.

 

Thaum lub load loj raug tshem tawm, nws tiv thaiv qhov hluav taws xob los ntawm spiking thiab puas cov khoom siv hluav taws xob.

4. Txhawb kev tiv thaiv muaj nuj nqi (txheej txheem ntawm txawv AVR qauv)

 

1. Tsawg-Kev Tiv Thaiv Zaus:Thaum lub tsev ceev ceev tsawg dhau (tsis txaus), excitation yog txwv los tiv thaiv cov cuab yeej puas los ntawm tsawg-voltage load;

2. Overvoltage txwv:Tshem tawm qhov hluav taws xob siab tshaj plaws thaum lub sij hawm ua txhaum los tiv thaiv kev tawg ntawm lub tshuab hluav taws xob winding thiab cov khoom siv hluav taws xob qis;

3. Soft Start Excitation:Maj mam nce qhov hluav taws xob thaum pib, zam kev cuam tshuam tam sim ntawd.

 

5. Parallel/Grid Connection Function (AVR for Paralleling Use)

Thaum ntau chav nyob ua haujlwm nyob rau hauv tib lub sijhawm, AVR tuaj yeem kho reactive fais fab kev faib tawm, kom ntseeg tau tias qhov voltage ntawm ntau chav nyob zoo ib yam, tiv thaiv cov circulating tam sim no thiab tsis sib tw rau reactive zog.

 

6. Qhov txawv ntawm Brushless thiab Brushed Generator AVR

1. Brushless Generator AVR: muab lub zog rau lub stator ntawm lub exciter, indirectly tswj lub magnetic teb ntawm lub ntsiab generator;

 

2. Brushed Generator AVR: ncaj qha xa cov excitation tam sim no mus rau lub rotor swb rings.

 

Cov tsos mob ntawm AVR puas tsuaj

 

1. Tsis muaj hluav taws xob tso tawm thaum pib;

 

2. Ib txwm voltage thaum unloaded, tab sis voltage poob sharply thaum loaded;

 

3. Voltage fluctuates unpredictable thiab tsis tuaj yeem ruaj khov;

 

4. Qhov hluav taws xob tseem muaj siab heev, nquag hlawv tawm lub teeb thiab cov keyboards.
