風力發電原理

How does a wind turbine work? You’ve probably seen a wind farm but do you know how wind force is converted into electrical energy. we are going to show you how a wind turbine works each wind turbine has a wind vane at the top that indicates the wind direction this allows the turbine to rotate on the tower. And face the wind the blades also rotate on their axis for maximum resistance wind force that is the kinetic energy contained in moving air currents spins the blades these are designed to fully capture its energy. They can be as long as 60 meters. Each and a made of very light and resistant materials for ease of movement this is why they can produce energy. Even with very light winds starting from about 11 kilometers per hour with very strong winds above 90 kilometers per hour. The blades are placed in the feathered position and the turbine stops spinning for safety reasons the blades are attached to the wind turbine. Through the hub which is coupled to the low-speed shaft the lo
