The initial investment in wind power generation is relatively large. The investment per unit kilowatt of wind power generation is much higher than that of thermal power generation and hydropower generation, so the grid-connected price of wind power is also higher than that of thermal power. However, in today's energy shortage situation, it still has incomparable advantages compared with nuclear power, hydropower, thermal power, etc. The technical status and actual operation of wind power show that the cost of building a wind farm is much lower than that of a hydroelectric power plant, a thermal power plant or a nuclear power plant. Wind power is a clean natural energy without the environmental pollution problems associated with coal power, oil power and nuclear power. Wind power generation does not require coal, oil and other fuels required for thermal power generation or nuclear materials required for nuclear power plants to generate electricity. There is no other consumption except routine maintenance.
Compared with other methods, the construction period of wind power is generally very short. The transportation and installation time of a wind turbine does not exceed 3 months. The construction period of a 10,000-kilowatt wind farm is less than a year, and the installation of one can One unit is put into production; the installed capacity is flexible and can be large or small according to actual needs, or can be determined according to the amount of funds, which brings convenience to raising funds; the operation is simple and can be completely unattended; the actual area is small, and the unit and monitoring , substation and other buildings only occupy about 1% of the land of the wind farm, and the remaining sites can still be used for grazing, fish farming, and growing crops; the land area requirements are low and can be constructed in hills, seasides, river embankments, deserts and other terrain conditions .
In addition, wind power has the characteristics of diversified power generation methods. It can be operated on the Internet, as a complementary system with diesel generators or independently, which can solve the problem of electricity consumption in remote areas without electricity. Provides realistic possibilities. Wind power generation devices can be purchased in any place where the wind is strong enough and suitable to generate electricity. Therefore, the current application of wind power can be said to be quite extensive, such as in mountainous areas, islands, remote areas, camps, floating islands, construction sites, lighthouses, radio stations, relay stations, etc. Used as self-contained power supply or auxiliary power supply for lighting, electric instruments, electrical appliances, irrigation, communications, air conditioning, heating, etc. These characteristics of wind power are its advantages.
Wind power generation is playing a huge role as an auxiliary energy source, but wind turbines still have some shortcomings. First, the energy output is unstable, especially the utilization rate of large wind turbines is low, and they are not yet qualified as independent energy sources; secondly, the safety and reliability of wind turbines are not fully guaranteed; in addition, the cost of wind turbines is not sufficient in the short term. to compete with fossil fuels. However, with the increasing human demand for energy and the development of science and technology, the above problems will eventually be solved.
Contemporary science and technology can already use wind power to generate electricity on a large scale. Although the current wind power generation accounts for less than 1% of the world's total power generation, with the continuous advancement of wind power technology innovation, it is expected that by 2020, it will be able to provide 10% of the world's electricity demand and create 1.7 million jobs. opportunities and reduce more than 10 billion tons of carbon dioxide emissions globally.
