Wind turbine technology is now relatively stable, whether domestic or foreign. If we look at wind turbines as a whole, the current level of processing and manufacturing domestically is too low, and many components simply cannot meet the technical requirements. Wind turbines typically have a lifespan of 20 years, but many components may only have a lifespan of 20 years. 5 years or even less.
Why do some electricity generating wind turbines not turn?
Wind energy production will harm the environment, harm the climate and cause noise pollution. The details are as follows:
1. harm the local ecological environment, such as the destruction of vegetation, modification of topography and relief, causing soil erosion and land desertification.
2. Wind power affects local climateal. Wind energy uses wind energy present in the atmosphere. According to the law of conservation of energy, the consumption and production of one type of energy must produce or consume another type of energy. . Therefore, wind turbines The process of generating electricity is inevitable.
3. The environment around the wind farm is good, so it will become a paradise for many birds, but a large number of birds will be injured by the wind turbines.
This reason is a bit broad. Discontinuation is a possibility. The variable pitch system may cause the blade angle to reach 90 degrees, which refers to the minimum upwind surface area of the blade, so the blade cannot fully face the wind, this which makes the wind speed reach the rated wind speed and cannot rotate. It is also possible that the yaw system prevents the blades from aligning with the wind and wind speed in winterr; is the same as the wind speed in summer, but the blades may rotate in winter, but they may not rotate in summer. They will rotate because the temperature is low in winter and the air density is high. In summer, the temperature is high. and the air density is low. This is what we Northeasterners often say: the wind in winter is strong, but the wind in summer is not strong.
