The functions of wind are as follows:
1. As a natural energy source, wind can exchange hot and cold air. Wind is now used to pump water and process food, and wind turbines can also be used to generate electricity.
2. It can complete the water cycle on earth, mix and balance heat and water vapor, and regulate temperature and humidity.
3. Wind transports and exchanges energy in the air, which can help crops grow.
4. Wind can spread pollen and plant seeds, helping plants pollinate and reproduce.
Wind is a natural phenomenon caused by the movement of air, caused by the heat of solar radiation. Sunlight shines on the earth's surface, causing the surface temperature to increase. The air on the surface expands under the effect of thehas heat, becomes lighter and rises. Once the warm air rises, the cold, low temperature air enters laterally. The rising air gradually cools, becomes heavier and becomes smaller. The higher surface temperature heats the air and causes it to rise.
Wind energy and photovoltaic energy are called “junk energy”. For what ?
The cost of solar power generation is high, and the current highest power generation efficiency is about 21%, and the average solar power generation efficiency electricity is about 15%. This type of energy production is mainly used for low-consumption electronic components. The efficiency of wind power generation is about 40-50%, and the cost is relatively low. However, it is indeed easy to damage it, because the generator is exposed to wind and sun all year round. Moreover, as the wind comes and goes, the power of sorgenerator tie changes. Additionally, electricity must be used at night, so batteries must be charged during the day to provide energy at night or to store electrical energy. As the output power of the wind turbine changes, the battery will be damaged during charging. (Different battery types have different charging methods.) Also. If your electrical devices use AC power, a DC-AC circuit board is required to discharge the battery. However, these items are now available in matching packages and manufacturers can customize them according to your needs, but they are quite expensive. Nowadays, wind power is mainly used on small fishing boats. In fact, these current electricity generation methods such as tidal, solar, wind and geothermal energy are not yet very mature and the prices are still relativelyhigh, so I suggest you buy a transformer worth tens of thousands of dollars to connect the lines. . Playing on mobile is tiring, and I don't ask for experience or wealth. Hope this helps you.
Wind power and photovoltaic power are new energy sources that China is striving to develop, and the power grid should fully absorb them and prioritize their use . Hydroelectricity also requires priority use of the electricity network during periods of flooding. This is a comprehensive consideration of a series of factors such as environmental protection and the reduction of carbon emissions by the State. The electricity network can therefore do nothing! Why is it called “junk electricity”? There are mainly two aspects.
First, photovoltaic and wind energy have low installed capacity and are dispersed, whichui makes it difficult to meet the peak load regulation needs of the power grid! To put it simply, when the weather is sunny and the wind is blowing, the insufficient thermal power will be supplemented. When short-term electricity demand increases rapidly, photovoltaic and wind power cannot meet it. On cloudy days and when there is no wind, the power plant is dead. In the event of a power outage, thermal energy is used! And the price of new electricity on the network is relatively high! This is what causes the sun to rise, the thermal power reduces the load and when the sun sets the thermal power increases the load. For the power grid, constant adjustments are required, which is not conducive to the safety and economical operation of the power grid. Second, wind and photovoltaic power are not stable enough, resulting in theharmonic transmission to the power grid system, which will increase power losses and affect motor efficiency, which will affect high-precision manufacturing! These two reasons should be the reason why photovoltaic and wind energy are called "garbage energy".
Both are new energy production, which are currently encouraged and vigorously developed by the state, and there are huge state subsidies. , the grid settlement price for thermal power is about 0.3 yuan per kilowatt hour, and the price of wind and photovoltaic power generation ranges from 0.3 to 0.8 yuan.
Both types of electricity generation had a fatal flaw at the time, namely their intermittency. Solar power produced electricity during the day and could not produce electricity at night. Wind power could produce electricity when there wasu wind. but could not produce electricity when there was no wind. These two types of power generation are actually not well received by the power grid, but due to state support for new energy and requirements for energy saving and emission reduction, the electricity network company must accept them unconditionally.
There are more and more of these two types of electricity production, which lead to instability in the electricity network. At present, we mainly rely on thermal energy peak shaving, pumped energy storage, wind energy heating and wind energy heating. building energy storage power plants to solve intermittent problems. At the same time, wind and solar energy forecasts are becoming more and more accurate, which also reduces pressure onregulation of the electricity network.
