An umbrella ladder high-altitude solar power generation system and its control method

Abstract

The invention discloses an umbrella-ladder high-altitude solar power generation system. The system comprises a cable at an angle with the ground and a plurality of solar power generation units arranged on the cable; and the solar power generation unit comprises an umbrella head device, an umbrella body of which the top center sleeves the cable, and an umbrella tail device which are arranged sequentially from bottom to top, wherein the umbrella head device is fixed on the cable, the umbrella tail device is connected with the top center of the umbrella body, the umbrella head device is connected with the edge of the umbrella body through umbrella ropes, the surface of the umbrella body is provided with thin-film solar energy, and the umbrella tail device is used for controlling and changing an irradiation area of the umbrella body which is irradiated by the sun. The invention also discloses a control method of the above system. Compared with the prior art, the umbrella-ladder high-altitude solar power generation system of the invention substantially does not occupy floor space, is just slightly affected by weather, enables greater sunlight radiation intensity and has a higher energy conversion rate; and the umbrella-ladder high-altitude solar power generation system can be matched with an existing power grid so as to improve the effective utilization rate of high-altitude solar power generation. The umbrella-ladder high-altitude solar power generation system of the invention is simple in structure; and the control method simple and effective and has high flexibility.

Description

technical field [0001] The invention relates to the field of high-altitude solar power generation, in particular to an umbrella ladder high-altitude solar power generation system and a control method thereof. Background technique [0002] Solar energy is a kind of clean energy, and the method of power generation is generally to build solar power stations on the ground. Due to the need to occupy cultivated land and mountain forests on the ground, urban land is limited, and the air cleanliness is poor. Cities with large electricity consumption, especially in the eastern region, have very limited land suitable for building solar power stations, while airspace such as sea, lake, river, and islands Wide areas cannot use solar energy, and in addition, the eastern regions of my country are rainy and cloudy in summer, so the utilization of solar energy in these regions is significantly lower than that in the western regions. The average effective utilization time of ground power gen...

Problems solved by technology

In addition, because the existing high-altitude solar power generation systems are mostly pasted on the airship or the surface of the aircraft, the area exposed to sunlight is fixed, and the power of power generation can only be changed according to the intensity of solar radiation at that time, which is difficult to adjust according to actual needs. The irradiated area has poor flexibility and is difficult to match with the current power grid, which makes it difficult to connect the solar power to the grid, which leads to a great waste of resources
