Wind power generator is a power equipment that converts wind energy into mechanical power, which drives the rotor to rotate and eventually outputs alternating current.Located in Denmark, the V164 is 220 meters high with three giant blades, each of which is 80 meters long. It can generate 260,000 degrees of electricity 24 hours a day, enough for hundreds of households to use electricity for one month.
With regard to this power generation, it is doubtful that everyone will have doubts. Can the wind turbines turn so slowly to generate electricity? Is there really so much power generation?Everyone has played with the hand-powered flashlight, shake it hard for a few times, the flashlight can really light up for a while, but the duration is not long.
Of course, the fan is different from this hand toy, it really generates electricity!
In fact, the reason for the slow speed of fan blades is very simple, which has a lot to do with their own weight and wind speed. The larger the fan, the longer the blade, the heavier the weight, and the slower the rotation. The blade weight of 1.5 MW fan is about 6 tons, which is 1.8 times of that of 0.75 MW fan, but it rotates 18 times per minute, only 3/4 of that of 0.75 MW fan. The speed of the fan blade also has a great relationship with the wind speed. The faster the wind speed is, the faster the fan rotates. When the wind speed of 1.5 MW fan reaches 3 meters per second, the speed can be increased by rotating gears, thus driving the generator to generate electricity.
Then, can the speed of fan blade increase infinitely with the increase of wind speed? That's definitely not.
When the wind speed exceeds the limit speed of the fan, the fan will stop working. Because if the speed is too fast and the centrifugal rate is greatly enhanced, the inertia trend will break the balance of the fan itself, and the blade will be easily broken. Therefore, each type of fan has the maximum speed. When the wind speed is too fast, it is necessary to operate the computer in the background, stop running the fan, and reduce the damage and wear caused by its inertia. This is equivalent to two identical cars, a speed of 30 kilometers per hour, a 200 kilometers per hour, which is easier to brake a reason. Therefore, the fan blade rotating slowly can more effectively protect the fan from injury.
In fact, the power output of the fan depends on the speed of the blade rotation. When the blade rotates at a constant speed, the power will increase with the increase of the blade force. The larger the blade of the fan, the greater the power, the more the corresponding power generation. For example, a 1.5 megawatt fan can generate 1,500 kilowatt an hour at full power. A family of three uses an average of 30 kilowatt-hour electricity per day during the summer rush season, which can last almost 50 days.
