Ayyuka na 10kV Feeder Voltage Regulators

Jirgin jiragen da yawan wurare da dama kamar tashar gine-gine masu harkar daidai. Amma a nan, zabe na sharhi a cikin jirgin jirage suna da inganci mai tsawo. Wannan babban irin suna haɗa da ziyarta a kan wuraren da ke 10 kV a cikin jirgen jirage, kuma a lokacin da take da shi ne suka zama rike zuwa wajen gine-gine ta hanyar zama da yawa.

Yanzu, akwai uku na bala da muhimmanci na addinin karfin jirgen jirage:

• Zamantakewa jiragen jirage: Yana bukata dukkiyar kudin da ya fi yawa.

• Kawo al'adu a kan maye na transformer mai tsari: Tana yi nasara a kan takalma bayan birnin substation. Amma, aiki da kowane lokaci yana iya tabbatar da abin da ake amfani da shi na transformer mai tsari kuma ba zan iya tabbatar da inganci na wuraren da ke ɗaya.

• Karfin kapasitoci da sauran kafin-kafin: Yana haɗa da ziyarta da ke kadan saboda kayayyakin kafin-kafin inda an yi jirgen jirage da kafin-kafin masu kayan aikata, amma kungiyoyin karfi na wuraren da ake iya yi shi ana ƙarin haske.

A nan, bayan tafiya, an fara da wani nau'in addinin karfin jirgen jirage - 10 kV feeder voltage regulator (SVR), wanda ya haɗa da inganci na wuraren da ke jirgen jirage. Kuma tun daga tafiya da dalilai na karfin karfinna wuraren da ke jirgen jirage a cikin jerin, ana iya samun cewa amfani da SVR ita ce mafi inganci a yau don karfin karfinna wuraren da ke jirgen jirage da ke 10 kV.

Misali na Amfani

Idan an yi misali da wuraren da ke 10 kV Tuanjie Line ta wani substation, tushen da ake yi waɗannan SVR shine:

• Saka wurin da ziyarta ta ƙarfin ci gaba da ma'aikata.

• Zabi ƙwarewar SVR idan an samu shi da yanayin da kaɗai a cikin wurin da ziyarta ta ƙarfin ci gaba.

• Bayyana ƙungiyoyin karfin karfinna wuraren da ake yi shi idan an samu shi da ziyarta da ke kadan.

• Zabi wurin da ake yi amfani da shi saboda ilimi da zaɓi game da yanayin da kaɗai a cikin wurin da ziyarta ta ƙarfin ci gaba.

Tushen Rike

Ishoshen Jirge:

• Hanyar: 20 km

• Mai hankali: LGJ-50

• Resistivity: R₀ = 0.65 Ω/km

• Reactance: X₀ = 0.4 Ω/km

• Transformer Capacity: S = 2000 kVA

• Power Factor: cosφ = 0.8

• Rated Voltage: Ue = 10 kV

Littafi 1: Rike Impedance na Jirge

• Resistance: R = R₀ × L = 0.65 × 20 = 13 Ω

• Reactance: X = X₀ × L = 0.4 × 20 = 8 Ω

• Active Power: P = S × cosφ = 2000 × 0.8 = 1600 kW

• Reactive Power: Q = S × sinφ = 2000 × 0.6 = 1200 kvar

Littafi 2: Rike Ziyarta na Wurare
ΔU = (PR + QX)/U = (1600×13 + 1200×8)/10 = 3.04 kV

Littafi 3: Zabi Ƙwarewar SVR

• Wurin da ake yi amfani da shi: 10 km daga wurin mai yawa (wurin da ake samu ziyarta 9.019 kV).

• Load at Critical Point: P = 1200 kW, cosφ = 0.8 → S = 1200/0.8 = 1500 kVA.

• Selected SVR Capacity: 2000 kVA.

Littafi 4: Ƙungiyoyin Karfin Karfinna Wurare

• Input Voltage: U₁ = 9 kV (measured)

• Target Output Voltage: U₂ = 10.5 kV

• Required Regulation Range: 0～+20%.

Littafi 5: Rike Ziyarta na Zabe
Ba a yi amfani da shi:

• Remaining Line Length: L₁ = 20 km - 10 km = 10 km

• Power Loss Reduction:
  ΔP = R₀ × L₁ × (S²/U₁² - S²/U₂²)
  = 0.65 × 10 × (1500²/9² - 1500²/10.5²)
  = 63.9 kW

• Net Reduction (after SVR loss): 63.9 kW - 4.4 kW = 59.5 kW

Abubuwan Farko:

• Annual Energy Savings: 59.5 kW × 24 h × 30 days × 4 months ≈ 450,000 kWh

• Cost Savings: 450,000 kWh × ¥0.33/kWh ≈ ¥60,000

• Revenue Increase: ¥80,000 annually

• Payback Period: <1 year

Wannan ya nuna cewa SVRs ita ce mafi inganci da mafi farko a yau don karfin karfinna wuraren da ke jirgen jirage.
