A 300 word essay on Zhangbei wind power generation.

I visited the Zhangbei power generation windmill during the summer vacation.

Wind power plants are actually known to everyone as "big windmills ". A motor is installed in the windmill. When the desert wind blows, it pushes the blades of the wind power plant (so these blades must be both light and strong) to spin, providing heat to the engine and then converting the heat. This is the whole process of producing wind energy. But the construction of this wind power plant also requires certain skills. The windmill blades cannot be too heavy, otherwise the wind may not be able to push the windmill. At the same time, the blades must be very strong, otherwise the sand will mix. with the wind in the desert, it will definitely break the leaves. At the same time, the part below the wind power plant must also be very resistant, because weWe all know that the power of sandstorms is very enormous. If the wind power plant is not well constructed, it may be blown away by the wind. Sandstorm.

So we must not only discover energy, but also protect it and create a beautiful “global village” with our hands!

The unit of wind energy power is W/m2 (Watts per square meter). When the average annual wind speed is 7 m/s, the wind power is 400 W/m2. the blades of the wind turbine, the greater the power of the wind. The scanning area is also larger (C = R2). The larger the sweeping area, the more wind energy it absorbs and the more electricity it generates.

Simply put, when wind speed is constant, the longer the blades, the more electricity is generated. Of course, you shouldn't stress it for too long, as problems can arise and it can be easily damaged.

The rThe reason they are thin is to reduce the mass of the blades, otherwise they would be too heavy to be blown by the wind and produce electricity.
