Insufficient capacity of a single machine
From the investigation of the development of wind power technology, it is found that the insufficient motor capacity of wind turbines is one of the key problems faced by current wind power technology. In recent years, wind power technology has The development of wind power generation is extremely rapid, especially the capacity of a single machine has expanded from the original 600KW to a capacity of 1.5MW. The capacity of a single machine has been greatly developed. However, judging from the operation of the overall wind power technology, the single capacity of wind power generation is still unable to meet today's requirements. Wind power demand.
Wind resources are unevenly distributed
Wind turbines are an important part of the wind power generation system, and their operating efficiency and safety will directly affect the operating efficiency of the wind power generation system. At this stage, due to the insufficient promotion of wind power technology, the reform of wind power technology in many areas is not in place, the safety performance of wind turbines is not high, and wind turbine accidents often occur, which greatly affects the normal operation of the wind power system. The overall safety and stability of the wind power generation system will be reduced, which is not conducive to the sustainable development of energy companies.
Increase research on wind power generation technology
We understand that in the process of development of wind power generation technology, insufficient single unit capacity is the main problem faced by current wind power generation technology. Therefore, in order to To better solve such problems, relevant research departments should increase research on wind power generation technology.
In the research and development of wind power generation technology, we should focus on the actual development of the region, especially the expansion of single unit capacity. In order to meet the demand for wind power generation, wind turbines with larger capacity are needed for support. , the increase in single machine capacity cannot be satisfied with the status quo, and should be continuously expanded. Moreover, the expansion of single machine capacity will also play a great role in enhancing the efficiency of wind power generation.
Based on the current development status and future development trends, the author believes that wind power generation technology should develop in the direction of large-scale wind power generation units. This is also the inevitable development direction of wind power generation in the future. This will promote the development of wind power generation. long-term development.
1. Wind lift:
Wind lift has been widely used since ancient times.
2. Wind power generation:
Wind power generation usually has three operating modes:
(1) It is an independent operation mode, usually a small generator is used to generate electricity. One or several households provide electricity, which uses batteries to store energy to ensure power usage when there is no wind.
(2) Wind power generation is combined with other power generation methods (such as diesel engine power generation) to provide power to a unit, a village or an island.
(3) Wind power generation is integrated into the conventional power grid to provide power to the large power grid. Often dozens or even hundreds of wind turbines are installed in a wind farm, which is the main development direction of wind power generation.
3. Sail to assist navigation:
In the development of today's motor boats, in order to save fuel and increase speed, ancient sails have been developed.
4. Wind powerHeating:
With the improvement of people's living standards, the demand for heat energy in household energy is increasing, especially in high latitudes in Europe and North America. Drinking water is a major energy consumer. In order to solve the heat energy needs of households and low-level industries, wind heating has been greatly developed.

Wind energy advantages and disadvantages
1. Advantages
Wind is a clean energy source. Wind energy installations have become more advanced, mass production has reduced costs, and in the right locations, wind power is now less expensive than other generators. Wind energy facilities are mostly non-three-dimensional facilities that can protect the land and ecology. Wind power is a renewable energy source that is environmentally friendly and clean. Wind power is energy-saving and environmentally friendly.
2. Disadvantages
The ecological problem of wind power is that it may disturb birds. For example, the grouse in Kansas, USA, have gradually disappeared after the emergence of windmills. The current solution is offshore power generation, which is more expensive but also more efficient.
In some areas, the economics of wind power generation are insufficient, and the wind in many areas is intermittent. What is worse is that in places such as Taiwan, there is less wind in summer and during the day when power demand is high. time; must wait for the development of energy storage technologies such as compressed air.
Wind power generation requires a large amount of land to build wind farms to produce relatively large amounts of energy.
When wind power is generated, the wind turbine will make a lot of noise, so it is necessary to find some open areas to build.
Current wind power generation is not yet mature and there is still considerable room for development.
