Description
Technical Field
The utility model relates to the technical field of power generation, in particular to spin ball wind power generation independent operation system and have power generation facility of this system.
Background
With the increasing shortage of fossil energy, new energy power generation technologies represented by solar energy, wind energy, water energy, biomass energy and the like are rapidly developed. In many new energy technologies, solar energy, wind energy and hydroenergy utilization technologies are relatively mature, but bottlenecks exist, for example, solar power generation is limited by weather, the conversion efficiency of a battery and other problems, and cannot be popularized and used on a large scale, and wind energy is easily influenced by factors such as regions and weather. In recent years, it has been found that, since the service life of a solar power generation device is about 20 years, the main equipment, silicon plates and metal materials are wasted, and for example, the silicon plates with extremely large usage amount are garbage which cannot be rotten for thousands of years.
10 months and 10 days in 2019, photovoltaic information is released: photovoltaic liability high-voltage early warning! The total liabilities of 21 listed companies exceed 3000 billion. High liability is a "tie spell" that most residential photovoltaic enterprises must face at all times. The total liabilities of these 21 enterprises reached 3023.41 billion of tongue-sucking. The liability rate was 58.77% relative to 5144.68 billion total assets, which still falls within the 60% red line range as a whole. Of these 21 enterprises, 7 enterprises had a liability exceeding 200 billion yuan and were approaching the end of the day.
Wind energy is increasingly gaining attention as a clean renewable energy source in all countries of the world. The storage capacity is huge, the global wind energy is about 2.74 multiplied by 109MW, and the available wind energy is 2 multiplied by 107MW which is 10 times larger than the total amount of water energy which can be developed and utilized on the earth. Wind has been used by people for a long time, mainly by pumping water and grinding surfaces through windmills, and nowadays, the whole society pays attention to how to generate electricity by using wind.
The kinetic energy of wind is converted into mechanical kinetic energy, and then the mechanical energy is converted into electric kinetic energy, namely wind power generation. The principle of wind power generation is that wind power drives windmill blades to rotate, and then the rotating speed is increased through a speed increaser, so that a generator is promoted to generate electricity. According to current windmill technology, the generation of electricity can be started at a breeze speed (in the order of breeze) of about three meters per second. Wind power generation is forming a hot tide in the world, because the wind power generation does not need to use fuel, does not generate radiation and air pollution, and does not leave garbage which is not rotten for many years.
Wind is a new energy with great potential, and in the beginning of the eighteenth century, one violent strong wind in two countries of English law is swept transversely, so that four hundred wind mill houses, eight hundred houses, one hundred churches and more than four hundred sailing boats are destroyed, thousands of people are injured, and twenty-five million big trees are uprooted. In the case of a tree pull only, the wind generates ten million horsepower, i.e., 750 ten thousand kilowatts of power, in a few seconds! It has been estimated that the wind resources available on earth to generate electricity are about 100 hundred million kilowatts, which is almost 10 times the amount of hydroelectric power generated worldwide. At present, the energy obtained by burning coal every year all over the world is only one third of the energy provided by wind power in one year. Therefore, great importance is placed on wind power generation at home and abroad, and new wind power generation energy is developed.
