Concentration solar wind power generation method

Abstract

The invention relates to a concentrated solar energy wind power generation method, which is characterized in that heat produced by the concentrated solar energy is used to heat the air below the cylindrical high tower; the hot air rises along the intracavity of the high tower, producing air convection; the wind power produced by air convection drives a wind power generator positioned at top end port of the high tower; a heat-collection plate is a conical cylinder with a top opening and a bottom opening, which is used to concentrate solar light; the top opening is matched with the lower end opening of the high tower; the heat-collection plate is composed of an inner glass layer and an outer glass layer, the space between the two layers is vacuum; the external surface of the inner glass is coated with spectrum selective absorption coating layer for absorbing solar radiation; due to the irradiation of solar light, photons impinge against the coating layer, and solar energy is converted to heat energy; the concentrated solar energy heats the air at the bottom of the high tower; as a result, hot air with low density rises, and the colder heavy air on the upper layer in the cylindrical high tower with large density descends, forming the up-and-down air convection; therefore, the wind speed in the higher tower increases gradually; the hotter the air, the stronger the air convection is and the more rapid the wind speed is; a stable wind speed is formed, driving the wind power generator on the top part.

Description

technical field [0001] The invention relates to a wind power generation method, in particular to a concentrated solar wind power generation method. Background technique [0002] Wind is one of the energy sources without pollution. Moreover, it is inexhaustible and inexhaustible; it is a new energy source with great potential. It has been estimated that there are about 10 billion kilowatts of wind power resources on the earth that can be used to generate electricity, which is almost the current hydroelectric power generation capacity in the world. 10 times. At present, the energy obtained by burning coal in the world every year is only one-third of the energy provided by wind power in a year. Therefore, both at home and abroad attach great importance to the use of wind power to generate electricity and develop new energy sources. [0003] my country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kW, of ...

Problems solved by technology

The utilization rate of the equipment is low and the loss of production is caused.

[0009] 3. Due to the intermittent nature of natural wind, the output of wind turbines fluctuates greatly, and the fluctuation time ranges from seconds to years

Fluctuations from seconds to minutes may affect transient stability, system frequency control, and load flow of conventional power generation equipment in a short period of time
