Jinsi ya kukokotoa Wind Turbine Output
Wind Turbine Output ni nini?
Wind turbine power output depends on wind speed, blade area, and efficiency. Power increases with the cube of wind speed.
Fomula
Calculate: P = 0.5 × ρ × A × v³ × C_p
- P
- 0 — 0
- A
- swept area — swept area
Mwongozo wa Hatua kwa Hatua
- 1Calculate: P = 0.5 × ρ × A × v³ × C_p
- 2ρ = air density (≈1.225 kg/m³), A = swept area, v = wind speed, C_p = efficiency (~0.35-0.45)
- 3Typical 2-5 MW turbine: 5-15 GWh/year depending on wind resource
Mifano Iliyotatuliwa
Ingizo
100 m rotor (7850 m² area), average wind 10 m/s, C_p=0.4
Matokeo
Average power ≈ 1.9 MW
Typical utility turbine
Makosa ya Kawaida ya Kuepuka
- ✕Using peak power output instead of average capacity factor
- ✕Neglecting wake effects between turbines
Maswali yanayoulizwa mara kwa mara
Why is wind speed raised to the third power?
Power proportional to kinetic energy (½mv²) and flow rate; combined gives v³ dependence.
How much area does a wind turbine need?
Large utility turbines need 2-5 acres minimum spacing; smaller residential turbines 0.5 acres.
