1. (1) Advantages of wind energy: huge potential, wide distribution, renewable and pollution-free.
(2) Disadvantages of wind energy: low density, instability, large regional differences, wide dispersion of wind energy, randomness and low energy density!
2. Wind power generation: The advantages of large-scale systems are high reliability of power supply to the system and low operation and maintenance costs. The disadvantage is the high cost of the system. .
The advantage of this small system is that it generates higher power, lower system cost and lower operation and maintenance costs.
The disadvantage is that small wind turbines have low reliability. .
..Due to the strong complementarity between solar energy and wind energy, hybrid wind and solar power generation systems compensate for the lack of resources of wind energy and independent photovoltaic systems
.
Wind engine is an energy conversion device that converts wind energy into mechanical energy.
As shown in Figure 1-4, the wind engine consists of 5 parts: ...The disadvantage is that it is difficult to start. ...The capacity of small wind turbines is not large, and the power generally ranges from a few watts to several kilowatts. Most of them have the advantages of simple structure and easy transportation. ...In the use 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 and the technological content is high. Power generation will be affected when solar power generation is affected. the weather is bad;
For the production of eo energylink, the worse the weather, the stronger the wind and the better the electricity production.
