400v 150kvar Ubonelelo lwaMandla oMbane oPhantsi oluFakelwe iSigaba esiThathu seSvg

Inkcazelo emfutshane:

I-static var generator isebenzisa i-IGBT ukulawula ixabiso kunye nesigaba se-AC voltage ye-inverter, ukwenzela ukuba isebenze injongo yembuyekezo esebenzayo kunye ne-harmonic.I-Static var generator svg inokubona imbuyekezo ekhawulezayo yomthwalo osebenzayo, kwaye izuze ukuchaneka kwembuyekezo ephezulu kakhulu.I-Noker static var generator idibanisa iteknoloji entsha ye-3-level, ethembekileyo kunye nokusebenza okuphezulu.

I-SVG static var generator okwangoku sesona sisombululo kulawulo lwamandla olusebenzayo olufakiweyo.I-SVG ikhawuleza (ngaphakathi kwe-10ms), ukuchaneka kwayo kwembuyekezo kuphezulu (into yamandla ngaphezu kwe-0.99), indlela yembuyekezo iyaguquguquka (i-SVG inokubuyekeza zombini amandla asebenzayo asebenzayo kunye namandla asebenzayo asebenzayo), kwaye i-SVG inomsebenzi wokuhluzwa okusebenzayo kwe-harmonic. yangoku.

I-rolling Mill, i-Arc furnace, i-Converter, i-Blaster furnace, i-Transmission system, i-Frequency converter, i-High power supply, i-UPS, i-Elevator, i-Super press, i-Cutting, umatshini wokulawula amanani, isibane se-Arc, isibane se-Halogen, i-Air conditioner.

Iimbonakalo

Isigaba sesithathu se-svg sihlola umthwalo wangoku nge-CT yangaphandle kwaye yenze i-computing nge-DSP yangaphandle ukuhlalutya umxholo osebenzayo womthwalo wangoku.Emva koko, ilawula i-PWM ye-generator yesignali esekelwe kwisethingi yokuthumela iimpawu zokulawula kwi-IGBT yangaphakathi.Ngale ndlela, ivelisa imbuyekezo esebenzayo ngoku ukuphumeza imbuyekezo yamandla asebenzayo.

1. Ixhasa iindlela zembuyekezo ezili-15 ngayo nayiphi na iprayorithi, efana ne-harmonic, amandla asebenzayo, ukungalingani kunye nembuyekezo ye-hybrid.
2. I-IGBT kunye ne-DSP chips ziimpawu ezithembekileyo.
3. Ukulawula ngokufanelekileyo ukunyuka kweqondo lokushisa kwezixhobo.
4. Ziqhelanise nemekobume yendalo erhabaxa kunye nokusingqongileyo kwegridi yamandla.

5. I-topology yamanqanaba amathathu, ubungakanani obuncinci kunye nokusebenza okuphezulu.
6. Ulwakhiwo lweFPGA, amandla ekhompyuter esantya esiphezulu.
7. I-algorithm enamandla, impendulo ekhawulezayo kunye nembuyekezo echanekileyo.
8. Ukubonelela ngeenkonzo ezilungiselelwe ulwakhiwo, isoftware, ihardware kunye nemisebenzi.
