How strong wind does a small wind turbine need?

China is rich in wind resources, but the distribution is uneven. When considering the purchase of small wind turbines, it is necessary to consider the wind conditions in each region and select appropriate wind turbines based on the actual situation. For small wind turbines, the value of wind power can only be brought into play if there are wind resources of level 3 or so. However, from the professional technical point of view, the wind speed is more than 4 meters per second to be in the state of power generation.

The following are some data measured for power, voltage and wind speed:

1、 1KW wind generator set, with rated voltage of 48V, rated wind speed of 8-10M/S and output power of 1KW/48V, is in charge state.

2、 2KW wind generator set, with rated voltage of 48V, rated wind speed of 8-12M/S and output power of 2KW/48V, is in charge state.

3、 3KW wind generator set, with rated voltage of 96V, rated wind speed of 8-14M/S and output power of 3KW/48V, is in charge state.

By analogy, the stronger the wind in the place where small wind turbines are installed, the better the power generation effect. In our country, there are many successful small and medium-sized wind power generation devices in operation. The average wind speed in most areas of China is more than 3 meters per second, especially in the northeast, northwest, southwest plateau and coastal islands; In some places, it is windy weather more than one third of the year. In these areas, the power generation efficiency of wind turbines is high and can achieve ideal power generation effect.
