1. (1) Advantages of wind energy: huge accumulation, wide distribution, renewable and pollution-free.
(2) Disadvantages of wind energy: low density, instability, large regional differences, wide-area dispersion and randomness of wind energy, and low energy density!
2. Wind power generation: The advantages of large-scale systems are high power supply reliability and low operation and maintenance costs. The disadvantage is high system costs. .
The advantages of small systems are high power generation, low system costs, and low operation and maintenance costs.
The disadvantage is the low reliability of small wind turbines. .
Since solar energy and wind energy are highly complementary, wind and solar hybrid power generation systems make up for the resource shortage of independent wind power and photovoltaic systems.
Trapped.
A wind turbine is an energy conversion device that converts wind energy into mechanical energy.
As shown in Figure 1-4, the wind engine consists of five parts:... Its disadvantage is that it is difficult to start. ...The capacity of small wind turbines is not large, the power is generally from a few watts to several kilowatts, and most of them have the advantages of simple structure and easy transportation. ..In the utilization of wind energy, energy storage is an important issue. ...
3. The advantages of wind power generation are:
The cost of solar power generation is too high, the technology content is high, and bad weather will affect power generation;
However, Wind power generation means that the worse the weather, the stronger the wind, the better the power generation.
The answer above is good, I will just add it. The author must not understand what kwh means. kw means kilowatts, h means hours, and kwh means kilowatt hours. To put it bluntly, it is what we usually say. Degree, what is the degree of electricity? To put it simply, a one-watt light bulb consumes one degree of electricity for 1000 hours. A 10-watt light bulb consumes one degree of electricity for 100 hours. A 1000-watt light bulb consumes one degree of electricity per hour. 3kw is 3000 watts, which means it can generate 3 degrees of electricity per hour. The poster asked the wrong question. It should be how many kilowatt-hours of electricity are generated per year. If the poster said how many watts of electricity can be generated per year, it would still be 3,000 watts. As for the number of kilowatt-hours of electricity, it is 3*24*365=26280 kilowatt-hours of electricity. Let’s compare and see how much more electricity is used than the original poster’s home. Some generators are 380v and some are 220v. Some are 24v car engines and are used for car charging. It doesn’t matter how many v. As long as it's 3000 watts. The power generation is 3000 watts. The original poster must also want to ask about the relationship between 220 and 3000 watts. Please ask the original question again.
