Why Wind Energy Is Renewable?

Wind power is the conversion of wind kinetic energy into mechanical kinetic energy, and then mechanical energy into electric kinetic energy, which is wind power generation. The principle of wind power generation is to use the wind to drive the windmill blades to rotate, and then to increase the speed of rotation through the speed increaser to prompt the generator to generate electricity.

Wind is one of the energy sources that have no public hazards. And it is inexhaustible. For coastal islands, grasslands and pasture areas, mountainous areas and plateaus where water and fuel are scarce and transportation is difficult, it is very suitable to use wind power generation according to local conditions. And wind power does not need to use fuel and does not produce radiation or air pollution.

As a clean and renewable energy source, wind energy is receiving more and more attention from countries around the world. The amount of wind energy in the world is huge, about 2.74×10^9MW, of which 2×10^7MW is available, which is 10 times larger than the total amount of water energy available on earth. The energy of wind is so huge that at present, the energy obtained by burning coal in the world every year is only one-third of the energy provided by wind in one year.

What's Conditions For Wind Farm Site Selection And How We Recover It?

Basic conditions for wind farm construction
1.first we need get the region's perennial wind source information, the annual average wind speed at the height of the wind turbine should not be less than 6m / s.
2.topography (preferably higher or closer to, for example, the sea).
3.laying the grid conditions, extreme weather conditions, local electricity price, etc.
4.the area should be large, at least a few square kilometers or more.
5.the establishment of wind measurement tower, measurement of wind resource data for more than a year, this requires the assistance of the relevant local departments.

How to get wind resource data
"Wind" refers to the horizontal movement of the atmosphere, in the direction of movement wind always blows from high pressure to low pressure, the ultimate source of wind energy is solar radiation energy, some regions on earth are very rich in wind energy resources, such as low latitude letter wind belt, prevailing westerly wind belt and polar easterly wind belt control areas, often very rich wind energy resources.
Relying on the professional team in the field of wind resources to collect long-term weather station data, mesoscale data (MERRA, AWS, Vortex, etc.) and wind measurement data from surrounding wind power projects near the intended area, analyze the potential wind energy resources in the intended area, and collect topographic data for modeling,
combine the meteorological data for flow field simulation, draw a wind energy resource distribution map of the intended area, and select areas with better wind energy resource distribution and construction The area with good wind resource distribution and good construction conditions will be selected as the potential development site.

9.xMW Series Wind Turbine Generator Application 

(1)Suitable for “desert,gobi and wilderness”
(2)Desertification design to enhance environmental adaptability.The design of desertification environment adaptability enhances the adaptability of the WTGS to corrosion,high temperature,sandstorm and ultraviolet light.
(3)Wind independent power generation. That means the wind turbine output power through the battery to the demand for power supply.
(4) Grid-connected wind power generation. This power supply method is to connect the wind turbine to the power grid and transmit the electricity from the wind turbine to the power grid. Wind power is integrated into the conventional grid operation to provide power to the larger grid.
(5) Wind / light system. It is also called "wind/light complementary" power generation system, which is a joint power supply system composed of wind turbines and solar cells. In the monsoon climate zone, this system can make full use of wind power and sunshine conditions to generate electricity and provide stable power output throughout the year.
(6) Wind/diesel power supply system. Wind turbines and diesel generators are combined in one system to supply power to the load. Wind power generation is combined with other power generation methods (such as diesel power generation) to supply power to a unit or a village or an island. This is a complementary energy generation method that uses wind power to generate electricity when there is wind and diesel generators to generate electricity when there is no wind.

This system can provide stable electricity and at the same time achieve the purpose of making full use of wind energy and saving fuel.
