Magalimoto Osiyanasiyana a AC 6.6kv 11kv 1000kW Medium Voltage VsD VfD

Kufotokozera Kwachidule:

Medium voltage drive ndi chipangizo chamagetsi chapamwamba kwambiri, chomwe chimayang'aniridwa ndi DSP, ndi SVPWM ndi cell muukadaulo wamagawo angapo kuti zitsimikizire inverter kuti igwirizane ndi minda yama mafakitale.

Zomwe zili mu harmonic ndizochepa kwambiri.Ili ndi mphamvu yayikulu kwambiri komanso mawonekedwe abwino otulutsa mafunde popanda zosefera zolowera, chipangizo chamagetsi chamagetsi ndi fyuluta yotulutsa.Kutentha kwa injini chifukwa cha ma harmonics ndi Torque ripple, phokoso, dv/dt, ndi zovuta zamagetsi wamba zimapewedwanso.Zimakwanira ma asynchronous ndi synchronous motors.

Zogulitsazo zidaperekedwa ngati zinthu zatsopano zazikulu mdziko mu 2003, ndipo zidagwiritsidwa ntchito kwambiri pakuwongolera magalimoto.

Mawonekedwe

1.Accurate zolakwika malo ndi kujambula ntchito
2. Unit bus voltage, ntchito yowonetsera kutentha
3. Magetsi ogwiritsira ntchito, panopa, mbiri yafupipafupi ikhoza kukhala yofunsa mafunso
4. Dual loop control power supply
5. Kuthamanga kwachiwiri kwa transformer kumagwiritsidwa ntchito ngati mphamvu zotetezera zosunga zobwezeretsera kuti zitsimikizire chitetezo cha dongosolo panthawi yogwira ntchito.
6. Njira zingapo zowongolera
7. Chisankho chaulamuliro wa m'deralo, ulamuliro wa bokosi lakutali, DCS control
8. Thandizani MODBUS, PROFIBUS ndi njira zina zoyankhulirana
9. Kukhazikika kwafupipafupi kungaperekedwe pomwepo, kuyankhulana kumaperekedwa, ndi zina zotero.

10. Thandizani mafupipafupi presupposition, mathamangitsidwe ndi deceleration ntchito
11. Ndi kachulukidwe wamphamvu kwambiri patsogolo pa anzawo
12. Voliyumu yaying'ono ya unit, kapangidwe kake
13. Makina onsewa ndi osakanikirana ndipo amatenga malo ochepa
14. Njira yabwino yotetezera
15. Chigawochi chili ndi mitundu 7 ya chitetezo, ndipo makina onse akugwirabe ntchito pambuyo polephera.
16. Makina onsewa akuphatikizapo chitetezo cha otembenuza pafupipafupi komanso chitetezo cha galimoto.
17. Kuchita bwino kwambiri
18. Woyang'anira PID womangidwa;
19. Ikhoza kusinthidwa kumadera osiyanasiyana ndi magawo a parameter, ndipo ma harmonics omwe alipo panopa ndi osachepera 2% (ovotera).

Mfundo yogwira ntchito

Kapangidwe ka JD-BP37/38 mndandanda wokwera voteji inverter kumaphatikizapo gawo kusuntha thiransifoma, maselo mphamvu ndi wolamulira.

6kV mndandanda inverter lili 5 maselo gawo lililonse, 15 maselo okwana.
10kV mndandanda inverter lili 8 maselo gawo lililonse, 24 maselo okwana.

Mapangidwe a cell cell ndiofala.Ndi AC -DC - AC single phase inverter circuit, rectifier diode ndi ya magawo atatu a full wave, IGBT 23inverter mlatho woyendetsedwa ndi ukadaulo wa sinusoidal PWM.Selo iliyonse yamagetsi ndi yofanana, ndizosavuta kutumiza, kusunga ndi kuchita zotsalira, ngati kulephera kukuchitika, milatho yam'mwamba imakhalapo kuti ikwaniritse njira yodutsamo ndipo zotsatira za inverter zikuchepa.
