How does wind power generation prevent the problems of excessive wind speed, excessive motor rotatio

Introduction How does wind power generation prevent the problems of excessive wind speed, excessive motor rotation, and excessive voltage? 1. The wind angle of the wind turbine impeller is adjustable when the wind force changes within a certain extent.

How does wind power generation prevent the problems of excessive wind speed, excessive motor rotatio

1. The wind angle of the wind turbine impeller is adjustable. When the wind force changes within a certain level, the blade torque can be maintained unchanged and the speed is stable;

2. The blade speed increases At this time, the power generation of the generator will also increase, and the energy consumed in power generation offsets the increased energy of the wind, making the motor speed stable;

3. The electric energy generated by wind power generation is converted and used by special equipment. The generator itself allows considerable fluctuations in power generation (voltage, current);

4. Wind power plants are built in locations with relatively stable wind power;

5. Pass With the above method, the wind turbine can generate stable power most of the time. If there are special circumstances (such as a super typhoon), special methods such as locking the blades and disconnecting the engine can be used to avoid accidents

What is the specific structure of the wind turbine blades?

Wind turbineshave pitch and yaw systems. The pitch system can When the wind speed changes, the windward angle of the blades is adjusted to optimize the rotation speed of the impeller and achieve maximum generator power; the yaw system can adjust the windward angle of the impeller and nacelle when the wind direction changes, so that the impeller always faces the wind direction. Work.

1. The cabin will change with the change of wind direction.

2. The nacelle and the impeller are mechanically connected together. When the wind direction changes, the impeller and the nacelle will remain perpendicular to the wind direction.

3. Changes in wind direction will not affect the output of the generator. Only when the wind speed changes will the output powerof the generator be affected.

Problems with wind power generation

Fan principle, however, in order to have a certain strength, the closer to the root of the fan blade, the thicker it becomes. Made of fiberglass. The reinforcing ribs made of fiberglass are placed in the mold and then injected with resin to form. The small air leaf has a solid structure, and the large one has a hollow structure. The hollow part of the large fan blade is almost half a cylinder. It is not an exaggeration to say that it is based on the principle of an airfoil. The installation angle of the fan blades is generally adjustable. The wind turbine has a complete constant speed device, and a device that automatically brakes, then turns, and finally rotates again when the wind direction changes. Don't do your own research and development. If you want to make a finished product for sale, just buy one and then reverse engineer it. You can search for "Manufacturing Process of FRP Fan Blades".

1: The blades of the windmill must be enlarged so that the windmill has enough power to drive the generator. The bigger the blades, the better.

2: The power of the windmill has increased, but the speed is not enough. You can give the generator a 2x gear to drive the generator. That is to say, one rotation of the windmill will drive the generator to rotate twice (professional The same principle applies to wind turbines) The prerequisite wind force must be sufficient. Coastal areas are best suited for wind power generation. Do not change the number of turns inside the generator. Your generator should be able to send out 14-1The voltage is 8V, and the power should be 200W. The simpler you make it, the better. The more complicated it is, the more power it will consume.
