The height of a wind turbine from the ground depends on many factors. In terms of wind capture, at the same location and time, the wind turbine is located at the bottom of the atmospheric troposphere, where the surface friction is lower and the air flow is better. That is, the higher the wind speed, the stronger the wind capture ability.

Wind is an inexhaustible and pollution-free energy source. Wind power generation is of great significance in any aspect. In this situation, the demand for wind turbines will continue to increase. But it seems that the wind turbines we see are basically three blades. Why not choose more blade designs?

Many people are curious why many wind turbines seem to be stationary there? In fact, there are usually two reasons for the fans in wind farms.

Generally speaking, for wind turbines, three-level wind has utilization value.

Due to unstable air flow, the alternating current output of the wind turbine, which varies from 13 to 25V, must be rectified through a charger and then charged into a battery to convert the electrical energy generated by the wind turbine into chemical energy. Then use an inverter power supply with a protective circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.

With the increasing types and quantities of wind turbines, the continuous operation of new units, and the aging of old units, the daily operation and maintenance of wind turbines are becoming increasingly important. Now let's discuss the operation and maintenance of the fan.

The installation location of small wind turbines is very important for power generation and safe operation. The following introduction is for reference:

Severe shaking of wind turbines can cause the following phenomena: unstable operation of the wind turbine, increased noise, significant vibration of the wind turbine head and body, and in severe cases, pulling up the steel wire rope can cause the wind turbine to fall and be damaged.

One is battery energy storage to ensure electricity usage when there is no wind; The second is to combine wind power generation with other power generation methods (such as diesel engine power generation) to supply electricity to units, villages, or islands; Thirdly, wind power generation is integrated into the conventional power grid for operation, supplying power to the large power grid. A wind farm often installs dozens or even hundreds of wind turbines, which is the main development direction of wind power generation.



The two main components of a wind power generation system are the wind turbine and the generator. The variable pitch control technology and variable speed constant frequency power generation technology of wind turbines are the development trends of wind power generation technology and the core technologies of wind power generation today. Here is a brief introduction to these two aspects.

Unlike hydraulic or thermal power generation, the water turbine or steam turbine that drives the generator to rotate has a relatively stable speed and torque, which can drive the generator and generate stable alternating current. After simple processing, it can be directly connected to the grid.

The old-fashioned wind power generation is direct current, which is converted into alternating current through an inverter. The new wind power generation is all AC based.
