DigiTsun Wind energy
Wind energy is the kinetic energy of air in motion. Wind energy, as an alternative to fossil fuels, is a clean and sustainable fuel source, it does not create emissions and it will never run out as it is constantly replenished by energy from the sun. It produces no greenhouse gas emissions during operation, and uses little land. In operation, the overall cost per unit of energy produced is similar to the cost for new coal and natural gas installations. Wind energy is used in various applications such as: Water pumping, Offshore platforms, Telecommunications, Commercial / Retail, Sailboats, Grid-tied electrical systems, Remote homes and cabins, Military Installations etc.
How Does a Wind Turbine Works?
When wind passes over the blades, it exerts a turning force. The rotating blades turn a shaft inside the nacelle, which goes into a gearbox. The gearbox increases the rotation speed for the generator, which uses magnetic fields to convert the rotational energy into Electrical Energy. This wind generator will typically generates power at around 700 Volts. The power produces at this voltage will be step up by step-up transformer to typically Most wind turbines start generating electricity at wind speeds of around 3-4 meters per second (m/s), (8 miles per hour); generate maximum ‘rated’ power at around 15 m/s and shut down to prevent storm damage at 25 m/s or above.
While renewable energy systems are capable of powering houses and small businesses without any connection to the electricity grid, many people prefer the advantages that grid–connection offers. connected system allows you to power your home or small business with renewable energy those period.
