Ma e jiri ya tụnyere MG set na IGBT, gịnị mere MG set ji dabara adaba maka ihe nnwale transformer ike? Olee ndị bụ ndị na-ebubata ngwaahịa na China na ụwa niile?
Ajụjụ gị bụ n'ezie mkparịta ụka teknụzụ a ma ama na ala ule transformer:
MG set (Motor-Jenerato) vs IGBT / solid-state frequency converter (SFC).
N'ọrụ, ọtụtụ nnukwu ụlọ ọrụ mmepụta ihe na-agbanwe ike ka na-ahọrọ MG set, ọkachasị maka nnwale voltaji na nha mfu. N'okpuru ebe a bụ ntụnyere bara uru eji eme ihe na ụlọ ọrụ transformer.
- MG Set vs IGBT Power Supply maka Nnwale Transformer

Setịpụ MG na-enye ike kwụsiri ike na voltaji/ugbua kwụsiri ike maka sistemụ nnwale.
- Ihe kpatara eji achọkarị MG Sets maka nnwale Power Transformer
2.1️⃣ Ike siri ike maka obere sekit na ibu ibu
N'oge ule dịka:
- Nnwale mgbochi mkpụmkpụ
- Nnwale mfu ibu
- Ule mmụba okpomọkụ
transformer nwere ike ịdọta nnukwu ọkụ eletrik na-agafe agafe.
Setịpụ MG na-anabata nke a nke ọma n'ihi inertia ha na-agbagharị agbagharị, ebe sistemụ eletriki nwere ike ịda ma ọ bụ belata ọkụ eletrik.
2.2️⃣ Ike dị elu (ọkwa MVA)
Ụlọ ọrụ transformer buru ibu nwere ike ịchọ:
- Ngwa nnwale MVA 5–20
- Mgbe ụfọdụ, 30 MVA ma ọ bụ karịa
MG na-eme ka nha dịkwuo mfe ruo n'ókè dị ukwuu.
Dịka ọmụmaatụ, a na-eji sistemụ MG nwalee transformers ruru 315 MVA / 400 kV n'ụlọ ọrụ ụfọdụ.
Ngwa ọkụ IGBT dị n'ọkwa a na-aghọ ihe dị oke ọnụ ma dịkwa mgbagwoju anya.
2.3️⃣ Ọdịdị ebili mmiri sinusoidal siri ike nke ukwuu
Nha ọnwụ chọrọ ọdịdị ebili mmiri ziri ezi nke ukwuu:
- Ule mfu isi
- Nnwale mfu ibu
Setịpụ MG na-emepụta ebili mmiri sine eke site na jenereta synchronous.
Ngwa IGBT na-emepụta usoro PWM ma chọọ nzacha, nke nwere ike iweta harmonics na-emetụta izi ezi nke nha.
2.4️⃣ Ikewapụ eletriki site na grid
Setịpụ MG na-enye ikewapụ igwe n'etiti grid na ihe nnwale, nke na-enyere aka:
- Belata nsogbu grid
- Meziwanye nkwụsi ike nha
- Chebe grid ahụ n'oge ule ike dị elu.
2.5️⃣ Mmepụta ugboro ugboro dị elu maka nnwale akpọrọ
Nnwale voltaji nke transformer na-akpata na-achọkarị:
- 100 Hz
- 150 Hz
- 200 Hz
Ngwa MG na-emepụta ihe ndị a ngwa ngwa site na ịgbanwe ọsọ jenerato ma ọ bụ nhazi ogwe osisi.
- Ihe Mere Ụfọdụ Ụlọ Ọrụ Ji Akwaga Sistemụ IGBT
N'agbanyeghị uru MG, sistemụ IGBT / Static Frequency Converter (SFC) nke oge a na-ewu ewu n'ihi:
- obere akara ukwu
- njikwa akpaaka
- mmalite ngwa ngwa
- obere mmezi igwe.
Ha na-enyekwa ohere maka ala nnwale akpaaka zuru oke na mmemme voltaji/ugboro mgbanwe.
Ọtụtụ ụlọ nyocha nnwale ọhụrụ na-ejikọta teknụzụ abụọ ahụ.
- Ndị Na-ebunye Ngwaahịa Kachasị Elu n'ụwa Nile (Sistemụ Ike Nnwale Mgbanwe)
Ndị na-ebubata ngwaahịa ụwa kachasị elu
- Siemens Energy - sistemụ nnwale transformer buru ibu
- OMICRON Electronics - sistemụ nchọpụta na ule mgbanwe
- Ụlọ ọrụ Doble Engineering - ngwọta nnwale transformer dị elu
- Megger Group - onye na-emepụta akụrụngwa nnwale ike eletriki
- HIGHVOLT Prüftechnik Dresden - voltaji dị elu na akụrụngwa ụlọ nyocha
Ụlọ ọrụ ndị a na-enye ụlọ nyocha nnwale transformer zuru oke.
- Ndị isi na-ebuga ngwa ahịa ndị China (MG Set / Sistemụ Nnwale)
China nwere ọtụtụ ndị na-ebunye ala ụlọ ọrụ mmepụta ihe mgbanwe.
Ngwa ndị na-ejikọta akụrụngwa
- Shanghai Trihope
- Ngwa ọrụ ike ọkụ eletrik Wuhan Huatian
- Ike ọzọ
Ụlọ ọrụ ndị a na-enyekarị:
- MG setịpụ
- sistemụ nnwale etinyere
- sistemụ nha mfu
- ụlọ nyocha ule transformer zuru oke.
- Eziokwu Ụlọ Ọrụ
N'ọtụtụ nnukwu ụlọ ọrụ mmepụta ihe mgbanwe ike (>220 kV):
Nhazi nkịtị:
Nnwale voltaji nke MG SET- ...
MG SET--- ule mfu ibu
IGBT/SFC --- Ntinye ihe mgbanwe enyemaka
Ya mere, MG set ka bụ isi ihe dị mkpa n'ala nnwale ike dị elu, ebe sistemụ IGBT na-enye mgbanwe
