Description

technical field [0001] The invention relates to a power generation system, in particular to a power generation system capable of simultaneously realizing wind power generation and solar photovoltaic power generation. Background technique [0002] With the development of China's economy, energy supply, energy security, greenhouse effect and environmental pollution are increasingly becoming major bottlenecks restricting China's economic development. According to the 2008BP World Energy Statistical Yearbook, the total consumption of commercial energy in China in 2007 was 1,863 million tons of oil equivalent, equivalent to 78.92% of the consumption of the United States. The huge energy demand has led China to use a large amount of highly polluting coal (coal The proportion of China's energy consumption is as high as 77.62%, which is much higher than that of the United States (24.86%) and leads to further deterioration of environmental problems. China's greenhouse gas emissions ...

Problems solved by technology

[0004] However, there are still many deficiencies and limitations in the current development and utilization of wind energy and solar energy: 1. The energy density and energy utilization efficiency of wind energy and solar energy are very low, so that large-scale power generation needs to occupy a large amount of land, so there is an urgent need to increase the unit land. 2. Wind and solar power generation are greatly affected by weather and regions, and their stability is poor. After grid-connected power generation, it will have a negative impact on the stable operation of the grid and the quality of power supply of the grid. Therefore, how to improve wind power generation And the stability of solar power generation is also a major issue; 3. Leaving buildings and deserts to build photovoltaic power stations will damage the environment and ecology, and a considerable part of the area under large fixed solar panels will be barren

Wind power generation also has certain environmental protection and ecological problems. Large-scale wind power stations are often built on the wind channel of the monsoon, and this is often the best route for migratory birds to migrate. The fast-rotating fan blades often become the killer of migratory birds; 4. Solar cells The heat island effect makes it impossible for solar panels to be placed horizontally and can only be placed obliquely, which causes turbulence when the wind passes by. Therefore, even if the wind energy resources in this area are relatively abundant, it is difficult for us to place wind turbines at high altitudes above the solar panels. Otherwise, the solar cells The turbulent flow generated by the inclined placement of the board will easily damage the fan blades and reduce the already low efficiency of wind energy utilization

And the low altitude (solar panel installation and motion trajectory space) is occupied by the solar panel and it is impossible to install the wind turbine. When the wind blows to the panel, a lot of energy is lost in vain.
