lub transformer yuav kos cov tam sim no loj heev.

 

Cov teeb tsa MG ua tau qhov no zoo vim lawv qhov kev sib hloov inertia, thaum cov tshuab hluav taws xob fais fab tuaj yeem ua rau lub zog hluav taws xob tsis ua haujlwm lossis txwv qhov tam sim no.

 

 

2.2️⃣ Muaj peev xwm fais fab loj (qib MVA)

 

Cov chaw tsim khoom siv hluav taws xob loj yuav xav tau:

• 5–20 MVA kev sim khoom siv
• Qee zaum 30 MVA lossis ntau dua

 

MG teeb tsa qhov ntsuas tau yooj yim rau qhov muaj peev xwm loj.

Piv txwv li, MG systems siv los sim txog li 315 MVA / 400 kV transformers hauv qee lub Hoobkas.

 

Cov khoom siv fais fab IGBT ntawm qib no dhau los ua kim heev thiab nyuaj heev.

 

 

2.3️⃣ Cov duab sinusoidal ruaj khov heev

 

Kev ntsuas kev poob yuav tsum muaj cov waveform raug heev:

• Kev ntsuam xyuas qhov poob ntawm lub hauv paus
• Kev sim poob ntawm qhov thauj khoom

 

Cov MG teeb tsa tsim cov nthwv dej sine ntuj los ntawm lub tshuab hluav taws xob synchronous.

 

Cov khoom siv IGBT tsim cov PWM waveform thiab xav tau cov lim dej, uas tseem yuav ua rau muaj kev sib haum xeeb uas cuam tshuam rau qhov tseeb ntawm kev ntsuas.

 

 

2.4️⃣ Kev rho tawm hluav taws xob los ntawm lub grid

 

Cov teeb tsa MG muab kev sib cais ntawm lub grid thiab cov khoom sim, uas pab:

• Txo cov teeb meem ntawm lub grid
• Txhim kho kev ruaj khov ntawm kev ntsuas
• Tiv thaiv lub grid thaum lub sijhawm kuaj fais fab siab.

 

 

2.5️⃣ Cov zis siab rau kev sim ua kom raug

 

Kev sim hluav taws xob uas ua rau lub zog hloov pauv hluav taws xob feem ntau yuav tsum tau:

• 100 Hz
• 150 Hz
• 200 Hz

 

MG teeb tsa tau yooj yim tsim cov no los ntawm kev hloov pauv qhov ceev ntawm lub tshuab hluav taws xob lossis kev teeb tsa ncej.

3. Vim li cas qee lub Hoobkas thiaj li tsiv mus rau IGBT Systems

 

Txawm hais tias MG muaj txiaj ntsig zoo li cas los xij, cov tshuab IGBT / Static Frequency Converter (SFC) niaj hnub no tab tom nrov zuj zus vim tias:

• qhov chaw me dua
• kev tswj hwm tsis siv neeg
