A wind turbine or wind generator is an installation designed to convert wind energy into electricity. The wind turns the screw, and from it the rotation is transmitted to the rotor, which generates electrical energy.
Wind turbines, sometimes called wind turbines, are installations capable of converting wind energy into electricity. The general principle of operation of a wind generator is simple - the wind turns the blades of a turbine, the rotation of which is transmitted to an electric generator that generates electrical energy.
Wind turbines are divided into two large groups - household and industrial. If several large industrial generators are networked together, a wind farm is created.
The main units of the wind generator are the wind turbine itself, the mast (tower) on which it is installed, and the electric generator. The electricity generated by the wind turbine goes to a battery or inverter, which is directly connected to the electrical network.
Industrial wind generators are additionally equipped with a brake system that regulates the speed of rotation of the turbine, a rotary mechanism, an anemometer and a ladder that allows you to climb to the turbine. The ladder is usually installed inside a wind turbine tower. The tilt angles of the wind turbine blades can be changed, which allows you to adjust the speed of its rotation and the efficiency of converting wind energy into electricity. Industrial wind turbines are necessarily equipped with a fire extinguishing system, a data transmission system for the operation of a wind generator and a lightning protection system.
Depending on the type of wind turbine, wind turbines can have a vertical or horizontal axis of rotation. The vertical axis is typical for rotary vane and carousel turbines, and the horizontal axis is for vane turbines. The advantage of rotary turbines is that their rotation does not depend on the direction of the wind, while wind turbines with a horizontal axis of rotation have to be oriented in the direction of air flow. On the other hand, horizontal-axis wind turbines are highly efficient and can convert up to 30% of wind energy into electricity, and the most efficient of rotary wind turbines - no more than 20%.
You can install an industrial wind generator on a pre-prepared foundation in 8-10 days. The procedures associated with obtaining permits and studying the air flows in a given area take much more time. Wind studies take at least a year, and approximately the same period is allotted for obtaining permits from regulatory authorities. A separate problem of wind generators is the icing of the blades in winter. Ice frozen on the blades increases their weight, which reduces the efficiency of the windmill.
