Data Source and Methodology
All calculations are based on standard wind power formulas as provided by authoritative sources in the field of wind engineering.
The Formula Explained
The power output formula is:
P = 0.5 × ρ × A × V³ × Cp × Ng × Nb
Glossary of Terms
Air Density (ρ): The mass per unit volume of air, typically in kg/m³.
Swept Area (A): The area covered by the wind turbine blades, in square meters.
Wind Speed (V): The speed of wind passing through the blades, in meters per second.
Power Coefficient (Cp): Efficiency factor of the turbine.
Generator Efficiency (Ng): Efficiency of converting mechanical power to electrical power.
Gearbox Bearing Efficiency (Nb): Efficiency of the mechanical components involved.
How It Works: A Step-by-Step Example
Imagine a turbine with an air density of 1.225 kg/m³, swept area of 50 m², and wind speed of 10 m/s. Using the formula, the power output is calculated as follows...
Frequently Asked Questions (FAQ)
What is the power output formula for wind turbines?
The formula for power output is P = 0.5 × ρ × A × V³ × Cp × Ng × Nb.
Why is wind speed cubed in the formula?
The power available in the wind is proportional to the cube of the wind speed, making speed a critical factor in the power output calculation.
