6kV Outdoor static var generator (SVG) 6kV Outdoor na Static Var Generator (SVG)

Product Overview

Ang 6kV outdoor static reactive power generator (SVG) ay isang high-performance dynamic reactive power compensation device na idinisenyo khususin para sa mga medium at mataas na volt na distribution networks. Ito ay gumagamit ng espesyal na disenyo para sa outdoor (protection level IP44) at angkop para sa komplikadong kondisyon ng trabaho sa labas. Ang produkto ay gumagamit ng multi chip DSP+FPGA bilang control core, na naglalaman ng instantaneous reactive power theory control technology, FFT fast harmonic calculation technology, at high-power IGBT driving technology. Ito ay direktang nakakonekta sa grid sa pamamagitan ng cascaded power unit structure, walang karunungan pangdagdag na boosting transformers, at maaaring mabilis at patuloy na magbigay ng capacitive o inductive reactive power. Sa parehong oras, ito ay nagsasagawa ng dynamic harmonic compensation, na epektibong nagpapabuti ng kalidad ng enerhiya, pinaigting ang estabilidad ng grid, at may mataas na reliabilidad, madaling pag-operate, at kampeon sa performance. Ito ang pangunahing solusyon para sa kompensasyon sa mga outdoor industrial scenes at power systems.

System structure and working principle

Core structure

• Cascade power unit: gumagamit ng cascade design, na naglalaman ng maramihang set ng high-performance IGBT modules, at nakakatanggap ng mataas na volt na 6kV~35kV sa pamamagitan ng series connection upang tiyakin ang matatag na operasyon ng equipment.

• Control core: Nakakamit ng multi chip DSP+FPGA control system, may mabilis na pagkalkula at mataas na kontrol accuracy. Ito ay sumasama sa iba't ibang power units sa pamamagitan ng Ethernet, RS485 at iba pang interfaces upang makamit ang status monitoring at command issuance.

• Auxiliary structure: Nakakamit ng grid side coupling transformer na may mga function ng filtering, current limiting, at suppressing current change rate; Ang outdoor cabinet ay sumasapat sa IP44 protection standard at angkop para sa harsh na outdoor environments.

Working principle

• Ang controller ay real-time na naga-monitor ng load current ng grid. Batay sa teorya ng instantaneous reactive power at FFT fast harmonic calculation technology, ito ay agad na nag-aanalisa ng kinakailangan na reactive current at harmonic components. Sa pamamagitan ng PWM pulse width modulation technology, ito ay kontrol ang switching state ng IGBT module, naggagenerate ng reactive compensation current na synchronized sa grid voltage at offset ng 90 degrees sa phase, na accurate na offset ang reactive power ng load, at dynamic na compensates para sa harmonic components. Ang ultimate goal ay ang i-transmit lamang ang active power sa grid side, na nagpapabuti ng multiple objectives ng power factor optimization, voltage stability, at harmonic suppression, na sinisiguro ang efficient at stable operation ng power system.
