It is used to produce electricity
Because it's my specialty
I don't know how old you are
Keep them simple things
p>It uses the principle of energy conversion. The wind can rotate the upper blades, which will generate kinetic energy. Kinetic energy can be converted into electricity using equipment.
The Three Gorges Dam uses water energy to produce electricity. The huge water drop can spin propellers and other things below, then convert that kinetic energy into electricity.
I don't know how to put it like that, you know?
Is it abandoned?
But in China, this is not unusual at all. Many things are not based on use value. As long as it pleases the leader....
Can wind turbines still produce electricity when there is no wind? Can they produce electricity?in ordinary times?
The wind turbines don't turn. The faster it goes, the more electricity it generates. Note that the power output of a generator can be roughly thought of as proportional to the product of speed and torque. The torque here is the electromagnetic torque obtained by the excitation of the generator. The torque is so great that the wind cannot move the turbine. At this time, the rotation speed is 0, the torque is very large, and the power output is 0. When the torque is zero, the speed accelerates to a very high level. It's actually a flying car, which is extremely dangerous. Since the electromagnetic torque is 0, the power output is 0. The power is 0 at both extremes, so there is an optimal speed that maximizes the power output.
The ideal value of this optimal speed can be calculated from Baez's theory, which is the ratio between the vlinear speed of the blade tip and the wind speed in front of the wheel. At a certain wind speed, there is a non-linear relationship between fan power and blade tip speed ratio. Through the theoretical derivation, the optimal peak speed ratio for each wind speed can be calculated. A wind turbine is a device that converts wind energy into mechanical energy, then allows machines to operate and finally generates alternating current. In fact, wind energy can also be considered solar energy because it is also used to generate electricity and is not harmful to our environment.
It is capable of producing a large amount of energy due to its internal structure, rather than depending on the external rotation speed of the blade. It's better to spin your own windmill faster. gear inside that turns silentlythankfully. The windmill rotates at a speed of 20 to 30 times per minute, and the wind is not enough. That doesn't mean it can't spin faster. This is due to the weight and length of the blades. you see it from a distance, don't think it's big, in fact it is. The blade is more than 20 meters long, and the weight can be imagined. If you turn too fast it will put a lot of pressure on the. base. If a generator collapses or its blades break, it could cause an accident and injure nearby residents. If it spins slowly, there will be no such thing. This will ensure that the windmill blades will not be injured, prone to accidents, and will not affect their power generation efficiency. After all, there's a little engine hidden inside! it, even if the strong wind outside turns very slowly. There are reducers and gears inside, and its speed will also increase by about fiftytimes, essentially maintaining a speed of about fifteen hundred revolutions per minute.
Yes, noIf so, the output voltage will change with the change of wind. When the wind is strong, the voltage will be high and when the wind is light, the voltage will be low. If the electrical appliances used do not have high voltage requirements, it can be d, but voltage requirements are not allowed for high-end electrical appliances (such as computers and others). If you continue to use them, it will damage the. electrical appliances ! You should pay attention to it!
Answer to your additional questions: First of all, the principle of voltage and current stabilization is that voltage stabilization can only be achieved when the power supply is large enough! When the power generated by wind energy is not sufficient (the wind is weak), the voltageion cannot be stabilized! The stability of wind energy production is not so continuous! Even if a voltage and flow stabilization device is added, the effect is still not satisfactory! The voltage and current stability of the intermediate link of the battery is the best, so it is better not to remove it! It can be used when wind power is insufficient (when the wind is weak), and the insufficient power can be temporarily supplied by the battery.
