No. According to Sina News query:
1. Wind power converts wind energy into mechanical energy through fan blades, and then converts it into electrical energy through gear sets and generators.
2. The wind force is constantly changing, so the amplitude and frequency of the generated alternating current also change, so the converter PCS is required to convert it into alternating current with a frequency of 50 Hz, and then through the box-type transformer transformer Connect to the grid. Therefore, they cannot be connected to the same bus.

Five misunderstandings about electric fans that are harmful to health:
1. Blowing for a long time
Many people like to blow for a long time If the electric fan stops just after cooling the body, the body will still feel hot, so it is not as comfortable as blowing it for a long time. However, if you are exposed to an electric fan for a long time, the body temperature will drop due to the evaporation of sweat, which can easily cause colds, colds, abdominal pain, diarrhea and other diseases. Generally, it is advisable to blow dry for half an hour to 1 hour at a time.
2. Blow quickly
In order to cool down as quickly as possible, some people turn on the electric fan to the fastest speed, thinking that the strong wind is enough to relieve fever. This is inappropriate practice. When the temperature exceeds 30°C, the air temperature is close to normal human body temperature, and the wind blown by the electric fan is also high-temperature wind. At this time, the body's heat should mainly be dissipated by evaporation of sweat.
3. Blowing close to the wind
The electric fan should not be placed very close to the body. If there is a strong wind blowing nearby and only blows on one side of the body, the wind-receiving side will be affected. Sweat on the skin evaporates quickly and the temperature drops significantly. On the side where the wind is not blowing, sweat evaporates slowly. As a result, the gap between blood circulation and sweat excretion on both sides of the body is too large, and the nerve center will lose balance. Once time passes, various organs will become exhausted. Unbearable and feeling unwell all over.

4. Electric fans that blow directional wind
are mostly oscillating fans. When blowing, the fan constantly moves its position and direction, and the blowing wind forms a big wave and a small wave, causing the body surface to slowly receive the wind. It will not make people feel too cold and the whole body temperature will be even. Therefore, it is best to use an oscillating fan instead of blowing directional wind.
5. Blowing while sleeping
That is, using an electric fan to cool down while sleeping. When a person is asleep, the functions of various organs in the body are reduced to the lowest level, all reflexes disappear, immunity is reduced, and diseases are easily caused.
How many kilowatt-hours of wind power does one circle of electricity
A 60m wind blade weighs three tons. A friend of mine drives a cart, and they often use carts to pull 60m wind blades. Once they encountered a big bumper on the way, so they drove the car to the ground pump and weighed it. The result showed that it weighed three tons. Everyone knows that 60m wind blades are among the three piers. I saw someone asking this question here, so I will answer it here by the way.
“The most difficult part of transporting wind power equipment is to transport the wind turbine blades. The blades are 50 to 60 meters long and weigh about 12 tons each. On this winding mountain road, it is really difficult for the transportation workers. It is a huge challenge, so we use special vehicles such as blade lifting trucks to transport wind turbine blades, which can adjust the blades according to road conditions.”
Recently, at Dongfang Electric Wind Power Company in Dechang County. Liangshan) Co., Ltd. happened to meet the transport truck that was loading the wind blades and was about to transport them away. Seeing that the wind blades that had been loaded onto the vehicle could actually swing and adjust their direction, Zhang Yong from the General Management Department Office answered the reporter's questions.
Wind power generates 2 kilowatt hours of electricity per turn.
The power of commonly used wind turbines in China is about 2000KW. When the wind is good, each device can generate about 2 kWh of electricity when it rotates once. Although wind power generation relies on wind power, it is unstable. As long as the wind speed can reach 3 meters per second, it can generate electricity. And in terms of consumables, it can be said to be "zero cost".
Compared with thermal power generation, wind power generation can be said to be low-cost and high-profit. Depending on the power of the wind turbine, there are certain differences in the amount of electricity that can be generated. The amount of power generated by one rotation is also fundamentally related to the power. Generally, a generator set with a power of 1500KW can generate 1500 kWh of electricity in one hour.
Wind power generation prospects
The development prospects of China's wind power and other new energy power generation industries are very broad, and it is expected to maintain rapid development for a long time to come. Profitability will also steadily increase as the technology matures. After 2009, the total profit of this industry will maintain rapid growth, and the growth rate will also reach more than 60%.
With the development of wind power, its cost performance is forming a competitive advantage with coal power and hydropower. The advantage of wind power is that every time the capacity is doubled, the cost drops by 15%. In recent years, the growth of world wind power has remained above 30%. With the localization of China's wind power installed capacity and the scale-up of power generation, the cost of wind power is expected to drop further. Therefore, wind power has begun to become a place for more and more investors to pursue gold.
