Frequently Asked Questions
How do I calculate wind turbine power output and energy production?
Wind power follows the cubic relationship: P = 0.5 × ρ × A × V³ × Cp, where ρ is air density, A is swept area, V is wind speed, and Cp is power coefficient (typically 0.35-0.45). Power output varies dramatically with wind speed - doubling wind speed increases power 8-fold. The calculator uses wind speed distribution data and turbine power curves to estimate annual energy production and capacity factors for site assessment.
What factors affect wind turbine site selection and performance?
Wind resource assessment requires minimum 10 mph average wind speeds for viability. Height increases wind speed (typically 10-15% per 30ft). Turbulence from obstacles reduces efficiency and increases wear. Air density affects power (decreases ~3% per 1000ft elevation). The calculator evaluates wind shear, turbulence intensity, and seasonal variations to predict turbine performance and optimize hub height selection.
How do I size electrical systems for wind turbine installations?
Wind turbine electrical systems require variable output handling, power conditioning, and grid interconnection equipment. Consider maximum power output for conductor sizing, transformer capacity, and protection coordination. Include power factor correction, harmonic filtering, and grid code compliance requirements. The calculator determines electrical infrastructure requirements including cables, transformers, switchgear, and grid interconnection costs for wind farm development.
