How fast does a wind turbine turn?
Wind turbines need a wind speed of at least 3 to 5 m s –1 to start turning. This is called the cutin speed. As wind speed increases, so increases the amount of power generated. At its rated wind speed (8 to 15 m s –1), the turbine is producing the maximum amount of electricity that the generators can handle.
How fast can a wind generator run?
Wind generators are generally designed to yield maximum output at high air speeds. Likewise, the manufacturers often rate their systems by the amount of power they can produce at a specific high wind speed, typically 24 mph (10.5 m/s) to 36 mph (16 m/s). In reality, in most areas you will rarely get these speeds.
How much power does a wind turbine generate?
Faster winds and larger-radius turbines allow greater power generation. Modern large wind turbines have a hub height (center of the turbine) of 80 m or more, to reach the faster winds higher above the surface. Turbines with radius of 30 m can generate up to 1.5 MW (mega Watts) of electricity, while blades of 40 m radius can generate up to 2.5 MW.
What is a variable speed wind turbine?
These variable-speed turbines can optimize power output without exceeding the turbine's performance limits. Common variable-speed wind turbines include pitch-controlled, stall- controlled, and active stall-controlled. An electronic controller checks the power output several times per second.
This engaging tutorial appears to offer an enticing solution for repurposing old CDs and harnessing solar energy, potentially contributing to environmental sustainability.
