- Sababta MG Sets-ka Badanaa Loogu Doorbido Tijaabada Korontada Beddelaha
2.1️⃣ Awood xooggan oo wareeg-gaaban iyo culeys-saarid ah
Inta lagu jiro baaritaannada sida:
- Tijaabada Impedance-ga Gaaban
- Tijaabada luminta rarka
- Tijaabada kor u kaca heerkulka
transformer-ku wuxuu soo jiidan karaa koronto aad u weyn oo ku meel gaar ah.
Qalabka MG si fiican ayuu ugu dulqaataa tan sababtoo ah firfircoonidooda wareega, halka nidaamyada korontada ku shaqeeya ay ku dhici karaan ama xaddidi karaan qulqulka.
2.2️⃣ Awood koronto oo sareysa (Heerka MVA)
Warshadaha waaweyn ee transformers-ka ayaa laga yaabaa inay u baahdaan:
- 5–20 sahay tijaabo ah oo MVA ah
- Mararka qaarkood 30 MVA ama ka badan
MG si fudud ayuu u dejiyaa cabbir weyn.
Tusaale ahaan, nidaamyada MG waxaa loo isticmaalaa in lagu tijaabiyo ilaa 315 MVA / 400 kV transformers-yada qaar warshadaha.
Sahayda korontada IGBT ee heerkan waxay noqdaan kuwo aad qaali u ah oo adag.
2.3️⃣ Qaab-dhismeedka hirarka sinusoidal ee aadka u deggan
Cabbiraadda khasaaraha waxay u baahan tahay qaab-dhismeed mowjad aad u sax ah:
- Imtixaanka luminta asaasiga ah
- Tijaabada luminta rarka
Qalabka MG wuxuu soo saaraa hirarka sine-ka dabiiciga ah ee ka yimaada matoor isku-dhafan.
Sahayda IGBT waxay soo saaraan qaab-dhismeedka PWM waxayna u baahan yihiin shaandhooyin, kuwaas oo wali keeni kara iswaafajin saameynaysa saxnaanta cabbirka.
2.4️⃣ Kala-goynta korontada ee shabakadda
Qalabka MG wuxuu bixiyaa go'doomin farsamo oo u dhexeeya shabagga iyo shayga tijaabada, kaas oo ka caawiya:
- Yaree khalkhalka shabakadaha
- Hagaaji xasilloonida cabbirka
- Ilaali shabaqyada inta lagu jiro tijaabooyinka awoodda sare leh.
2.5️⃣ Wax soo saar soo noqnoqosho sare leh oo loogu talagalay tijaabada la kiciyay
Tijaabada danabka ee ay keento transformer-ka korontada ayaa inta badan u baahan:
- 100 Hz
- 150 Hz
- 200 Hz
Qalabka MG si fudud ayuu u soo saaraa kuwan isagoo beddelaya xawaaraha matoorka ama qaabeynta tiirka.
- Sababta Warshadaha Qaar U Guurayaan Nidaamyada IGBT
Iyadoo ay jiraan faa'iidooyinka MG, nidaamyada casriga ah ee IGBT / Static Frequency Converter (SFC) ayaa caan noqonaya sababtoo ah:
- raad yar
- xakamaynta otomaatiga ah
- bilow degdeg ah
- dayactirka farsamada oo yar.
Waxay sidoo kale u oggolaanayaan sagxadaha tijaabada oo si buuxda otomaatig u ah iyo barnaamij dabacsan oo danab/soo noqnoqosho ah.
Shaybaarro badan oo tijaabo ah oo cusub ayaa isku daraya labada teknooloji.
