Wind power generation, because a single wooden rotor can be used for a long time, it is cheap, and you can stack more if needed. Wind power is the best for early stage power generation. Wooden rotors are the cheapest rotors. If you feel that the power is not enough later, you can switch to steel rotors or carbon rotors. Iron rotors are not recommended. They are only a little taller than wooden rotors. If this material is available to make iron rotors, I will It is recommended that you stack more wind turbines. The advantage of the steel rotor is that it will rotate no matter how low the wind force is, while the carbon rotor will not rotate if the wind force becomes smaller. Of course, exiting and re-entering can make the stopped carbon rotor operate again. The highest value in wind power generation is the carbon rotor, which can reach 170EU/t if you are lucky during thunderstorms. The disadvantage of wind power is that it has to be built on the 160th floor to put the wind kinetic energy generator, which consumes a lot of cables to connect to the land, and also consumes a lot of iron. If you feel that it is not enough later, you can choose nuclear energy. Nuclear energy is a power generation that has both profit and risk. If it explodes accidentally, your home will be gone. If it is used well, it is a magic weapon, but if it is not used well, it is garbage.
When the wind turbine is operating normally, will there be negative power?
The adverse effects of wind power generation on the environment are as follows:
1. Wind power generation will harm the local ecological environment, such as destroying vegetation, changing the topography, causing soil erosion and desertification.
2. Wind power affects local climate. Wind power uses wind energy in the atmosphere. According to the law of conservation of energy, the consumption and production of one kind of energy must produce or consume another kind of energy. Therefore, wind turbines The power generation process must consume part of the wind energy in the atmosphere. As one of the important factors of climate change, wind energy changes will inevitably bring about climate changes.
3. The environment around the wind farm is good, so it will become a paradise for many birds, but it will cause a large number of birds to be harmed by wind turbines.
4. Noise hazards from wind power generation.
In fact, wind turbines do cause a lot of unavoidable harm during operation. However, the utilization and development of any kind of energy will more or less cause certain harm to nature. harm.
For example, fossil energy coal and oil will produce a large amount of carbon dioxide and other harmful gases during combustion and cause a serious greenhouse effect. Even if wind power generation changes the microclimate, microenvironment and temperature of local areas, But from the perspective of the general environment and climate, the degree of harm is far less than the harm caused by the burning of fossil energy.
Negative power may occur when the grid-connected wind turbine is running. Generally, it occurs when the wind speed is near the starting wind speed. Since the output power of the wind turbine is very small at this time, when the wind speed suddenly When the wind speed becomes low or the wind direction changes, the unit will not stop running immediately, but will yaw or continue running for a period of time. At this time, negative power often occurs. If the wind speed is lower than the low wind cut-out wind speed, the negative power exceeds the limit or If the specified time is exceeded, the wind turbine willCut out the operation and enter the wind waiting state.
