Paano Kalkulahin si Wind Turbine Output
Ano ang Wind Turbine Output?
Wind turbine power output depends on wind speed, blade area, and efficiency. Power increases with the cube of wind speed.
Pormula
Calculate: P = 0.5 × ρ × A × v³ × C_p
- P
- 0 — 0
- A
- swept area — swept area
Step-by-Step na Gabay
- 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
Mga Nalutas na Halimbawa
Input
100 m rotor (7850 m² area), average wind 10 m/s, C_p=0.4
Resulta
Average power ≈ 1.9 MW
Typical utility turbine
Mga Karaniwang Mali na Dapat Iwasan
- ✕Using peak power output instead of average capacity factor
- ✕Neglecting wake effects between turbines
Mga madalas itanong
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.
