You can consider this method:
Connect the generator with a purely resistive fixed load with sufficient power, and install a wind speed sensor near the wind turbine (unit price is about 400 yuan). Use a computer to synchronously measure the generator output voltage and wind speed at intervals (such as 5 minutes) and save the data. Then the obtained two sets of data are calculated and analyzed to obtain the output power of the generator at different wind speeds.
The key here is that you need a multimeter with RS232 (or other interface) output, and the voltage signal (or pulse signal) output by the wind speed sensor needs to be converted before it can enter the computer.
Yes, the cabin can be rotated and is always facing the wind. The technical term is yaw. Of course, the nacelle will not always rotate in one direction, such as clockwise or counterclockwise. If the wind direction is unlucky, it will always move in the same direction. The fan will rotate at most seven or eight hundred degrees, and it will also have to actively rotate. This is called unmooring. . Prevent the cables inside from being pulled off.
A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a director (tail), a tower, a speed limiting safety mechanism, and an energy storage device.
Extended information:
The principle of wind power generation is to use wind power to drive the windmill blades to rotate , and then increase the rotation speed through the speed increaser to promote the generator to generate electricity. According to current wind turbine technology, power generation can start at a breeze speed of about three meters per second (the level of breeze). Wind power is becoming a craze around the world because it has no fuel problems and does not produce radiation or air pollution.
Broadly speaking, a wind turbine is a heat energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power uses natural energy. It is much better than diesel power generation. But if it is used in an emergency, it is still not as good as a diesel generator. Wind power is not considered a backup power source, but it can be used for the long term.
