Explained

What is the Wind Turbine Power Simulator?

Change wind speed, blade length, pitch and blade number and see the power curve and Betz limit. It runs in your browser, so a change to a setting or a drag on an object shows up at once.

Wind farms supply a growing share of electricity, and engineers use power curves like this to plan them.

3 steps to your result

Open the tool and follow along. Nothing to install.

In the Wind Turbine Power Simulator, use the controls to change Wind speed, Blade pitch angle, Blade length, Blades. The simulation reacts instantly.

Start with this experiment: Raise the wind speed from 6 to 12 m/s. Drag any glowing handle, object or slider with your mouse or finger and the Wind Turbine Power Simulator responds in real time.

Change one setting at a time and watch which readout moves, then compare it with this idea: Wind power = ½ ρ A v³ Cp.

What you get

Key idea 1

Wind power = ½ ρ A v³ Cp.

Key idea 2

Doubling the wind speed gives eight times the power.

Key idea 3

Longer blades sweep a larger area (A = πR²).

Experiment 1

Raise the wind speed from 6 to 12 m/s.

Experiment 2

Lengthen the blades to 80 m.

Experiment 3

Increase the wind to 30 m/s and watch the turbine park.

Questions people ask

How does wind speed affect power?

Power depends on the cube of the wind speed, so a small increase in wind gives a large increase in power.

Why do turbines stop in a storm?

Above the cut-out speed the blades are parked to avoid damage.

Is the Wind Turbine Power Simulator free to use?

Yes. The Wind Turbine Power Simulator is free, needs no signup or download and runs in your web browser. It is part of the Engineering group of AZRS simulations.

Does the Wind Turbine Power Simulator work on a phone or tablet?

Yes. The Wind Turbine Power Simulator takes touch input as well as mouse input, so you can use its 4 adjustable settings with a finger. A larger screen makes the controls and graphs easier to read.

How do I use the Wind Turbine Power Simulator?

1. In the Wind Turbine Power Simulator, use the controls to change Wind speed, Blade pitch angle, Blade length, Blades. The simulation reacts instantly. 2. In the Wind Turbine Power Simulator, pick an option such as 2, 3, 4 to switch modes or load an example. 3. Start with this experiment: Raise the wind speed from 6 to 12 m/s. Drag any glowing handle, object or slider with your mouse or finger and the Wind Turbine Power Simulator responds in real time. 4. Change one setting at a time and watch which readout moves, then compare it with this idea: Wind power = ½ ρ A v³ Cp.
