How Do Coemi-Skywing Wind Turbines Work?
There are four basic ways of explaining the question, "How do wind turbines work?" Our turbines typically consist of two or three blades, which spin as the wind comes into contact with them. These turn a shaft, which is connected to a generator, which then makes electricity.
1. Speed
How does a wind turbine work? It goes without saying that wind speed is vital in determining how much electricity your Coemi wind turbine can produce. Measuring wind speed is achieved through a built-in wind speed anemometer. This carries information to a Mitsubishi controller (which starts up the turbine). At the minimum of 5mph, the turbine starts converting a light breeze into power. At the maximum of 40mph, equivalent to gale force, the turbine safely and intelligently turns away from the wind to prevent it from being damaged.
2. Direction
Wind direction also measured by the Mitsubishi controller automatically operates a hydraulic motor in the head to move the turbine into the wind once the wind speed reaches 2.5 m/s or 5.5 mph. One the generator reaches maximum output the, the controller automatically moves the head to 45 degrees to the wind to stop over generating. Unlike other small wind turbines which use a dump to burn off excess generation, 100% of generated power is passed to the grid with the Coemi-Skywing synchronous wind turbines.
4. Revs
The Coemi-Skywing wind turbines have a fixed rotation speed with its 50Hz generator. The local grid voltage is matched automatically through the generators Electro magnets. Unlike other permanent magnet small wind turbines which are usually 20Hz variable voltage and require rectification to DC before conversion to AC through an inverter.
5. Power
As the wind strength builds the torque is converted through the gearbox to the generator and load is automatically increased producing amps. These amps are directly transmitted to the grid through a total generation meter registering the total kWh’s generated. This total is used for the payment of your FIT (feed in Tariff). Your system will absorb this power lowering your energy usage and any excess that escapes will register on your export meter earning you valuable income from your supplier.
6. Safety
The Coemi-Skywing has a double safety system to protect against over speed from high winds and loss of grid. Through the Mitsubishi controller a double hydraulic disc brake is applied and the head is turned away from the wind through the hydraulic head motor. Not only are blades and generator protected the life of the turbines and blades are increased, maintenance is also reduced.
