Ugereranyije n'itsinda rya MG na IGBT, kuki itsinda rya MG rikwiriye cyane imashini ipima transformer? Ni bande batanga serivisi zikomeye mu Bushinwa no ku isi yose?
Ikibazo cyawe mu by'ukuri ni ikiganiro cya tekiniki gisanzwe mu igorofa ry'ibizamini bya transformer:
Seti ya MG (Moteri-Jenereta) ugereranije na IGBT / ihindura frequency ya solid-state (SFC).
Mu by’ukuri, inganda nyinshi nini zikora transformer ziracyakunda seti za MG, cyane cyane ku igeragezwa ry’amashanyarazi aterwa n’ingufu no gupima igihombo. Hano hepfo hari igereranya rifatika rikoreshwa mu nganda zikora transformer.
- MG Set vs IGBT Power Supply yo gupima Transformer
| Ikintu | Seti ya MG (Jenereta ya Moteri) | IGBT / Ihinduranya ry'Impinduramatwara Ihoraho |
|
|
|
|
| Ikoranabuhanga | Imashini izunguruka (generator ikoresha moteri) | Inverter y'amashanyarazi ikoresha amashanyarazi |
| Ubushobozi bw'ingufu | Ni nini cyane (MVA nyinshi byoroshye) | Ni nini ariko irahenze ku ngufu nyinshi cyane |
| Imiterere y'umuraba | Umuraba mwiza cyane wa sine | Ishobora kuba irimo amahurizo yo guhinduranya |
| Ubushobozi bwo gukoresha amashanyarazi make | Birakomeye cyane | Bigengwa n'ibikoresho by'ikoranabuhanga |
| Ubushobozi bwo kurekura ibintu byinshi | Byiza cyane | Hafi |
| Kwizerwa | Ikomeye cyane | Ifite ingaruka mbi ku bushobozi bwa semiconductor |
| Gusana | Gusana imashini | Gusana bike kwa mekanike |
| Ingano | Kinini | Ntoya |
Seti za MG zitanga amashanyarazi yigenga hamwe n'amashanyarazi adahindagurika kuri sisitemu zo gupima.
- Impamvu Seti za MG zikunze kwifashishwa mu igeragezwa rya Power Transformer
2.1️⃣ Ubushobozi bukomeye bwo gukoresha umuvuduko mugufi no gupima umubyimba mwinshi
Mu gihe cy'ibizamini nka:
- Ikizamini cy'impedansi y'urujya n'uruza rw'amashanyarazi (short-circuit impedance test)
- Ikizamini cyo gutakaza imizigo
- Ikizamini cyo kuzamuka k'ubushyuhe
transformateur ishobora gukurura umuyoboro munini cyane w'amashanyarazi udahinduka.
Ibi byose bya MG bibyihanganira neza kubera ubushyuhe bwabyo buzenguruka, mu gihe sisitemu z'amashanyarazi n'amashanyarazi zishobora gucika cyangwa kugabanya umuvuduko w'amashanyarazi.
2.2️⃣ Ubushobozi bw'ingufu nyinshi (urwego rwa MVA)
Inganda nini zihindura amashanyarazi zishobora gukenera:
- Ikoreshwa ry'ibizamini bya MVA 5–20
- Hari igihe MVA 30 cyangwa irenga
MG ishyiraho ingano yoroshye kugeza ku bushobozi bunini.
Urugero, sisitemu za MG zikoreshwa mu kugerageza transfoma za MVA / 400 kV zigera kuri 315 mu nganda zimwe na zimwe.
Ingufu za IGBT kuri uru rwego zirahenda cyane kandi ziragoye.
2.3️⃣ Imiterere y'umuraba wa sinusoidal ihamye cyane
Gupima igihombo bisaba imiterere nyayo y'umuraba:
- Ikizamini cy'igihombo cy'ibanze
- Ikizamini cyo gutakaza imizigo
Seti za MG zikora umuraba w’ingirabuzimafatizo karemano uturutse kuri moteri ikora kuri synchronous.
Ibikoresho bya IGBT bitanga imiterere ya PWM kandi bigakenera filters, zishobora gukomeza gushyiramo harmonics zigira ingaruka ku buryo bwo gupima.
2.4️⃣ Gutandukanya amashanyarazi n'urukuta rw'amashanyarazi
Seti za MG zitanga uburyo bwo kwitandukanya hagati y’urusobe rw’amakuru n’ikintu cyo gupima, ibyo bikaba bifasha:
- Gabanya imivurungano y'urusobe rw'amazi
- Kunoza uburyo ibipimo bihagaze neza
- Rinda grid mu gihe cy'ibizamini by'ingufu nyinshi.
2.5️⃣ Umusaruro ukabije wo gupima hakoreshejwe imbaraga
Ikizamini cy'amashanyarazi giterwa na transformer gikunze gusaba:
- 100 Hz
- 150 Hz
- 200 Hz
Ibi bikoresho bya MG byoroshye kubibyaza umusaruro binyuze mu guhindura umuvuduko wa generator cyangwa imiterere ya pole.
- Impamvu zimwe na zimwe zirimo kwimukira kuri sisitemu ya IGBT
Nubwo hari ibyiza bya MG, sisitemu zigezweho za IGBT / Static Frequency Converter (SFC) zirimo gukundwa cyane kubera:
- ikirenge gito
- igenzura ryikora
- gutangira vuba
- gusana imashini nke.
Binatuma habaho igeragezwa ryikora ku buryo bwikora kandi bigakorwa hifashishijwe amashanyarazi/frequency.
Laboratwari nyinshi nshya z'ibizamini zihuza ikoranabuhanga ryombi.
- Abatanga serivisi zikomeye ku isi (Sisitemu z'ingufu zikoreshwa mu gupima transformer)
Abatanga ibicuruzwa bakomeye ku isi
- Siemens Energy – sisitemu nini zo gupima transformer
- OMICRON Electronics – sisitemu zo gusuzuma no gupima transformer
- Isosiyete ya Doble Engineering - ibisubizo bigezweho byo gupima transformer
- Megger Group – uruganda rukora ibikoresho byo gupima ingufu z'amashanyarazi
- HIGHVOLT Prüftechnik Dresden - amashanyarazi menshi hamwe nibikoresho bya laboratoire
Izi kompanyi zitanga ahanini laboratwari zuzuye zo gupima transformer.
- Abatanga serivisi zikomeye mu Bushinwa (MG Set / Sisitemu zo Gupima)
Ubushinwa bufite abatanga serivisi nyinshi zo gupima igorofa rya transformer mu ruganda.
Ibikoresho bihuza
- Shanghai Trihope
- Ikoranabuhanga ry'amashanyarazi rya Wuhan Huatian
- Ingufu zongeye gukoreshwa
Izi sosiyete zisanzwe zitanga:
- Amaseti ya MG
- sisitemu zo gupima ziterwa n'impamvu
- sisitemu zo gupima igihombo
- Laboratwari yuzuye y’ibizamini bya transformer.
- Ukuri mu nganda
Mu nganda nyinshi nini zihindura ingufu (>220 kV):
Imiterere isanzwe:
Ikizamini cya MG SET---cyatewe n'amashanyarazi
Ikizamini cyo kugabanya umutwaro cya MG SET---
IGBT/SFC --- Itangwa ry'ibikoresho by'inyongera
Bityo rero, seti za MG ziracyari inkingi y'imashini zipima zifite imbaraga nyinshi, mu gihe sisitemu za IGBT zitanga ubworoherane.
