Concentrated solar energy wind power generation method

Abstract

Disclosed is a concentrated solar energy wind power generation method. Heat generated by concentrated solar energy is used for heating air below a cylindrical high tower, hot air rises along an inner cavity of the high tower to generate convection, and wind generated through air convection drives a wind driven generator located on a top end opening of the high tower; a heat collection plate is adopted in solar energy concentration, and the heat collection plate is a conical cylinder with openings in the upper portion and the lower portion; an opening in the top is matched with an opening in the lower end of the high tower; the heat collection plate is composed of inner layer glass and outer layer glass, and the position between the inner layer glass and the outer layer glass is vacuum; the outer surface of the inner layer glass is coated with a spectral selective absorbing coating to absorb solar radiation energy; through sun irradiation, photons impact the coating, and the solar energy is converted into heat energy; the gathered solar energy heats air at the bottom of the high tower, the density of the hot air is small, the hot air is light and rises, cold air on the upper layer inside the cylindrical high tower is large in density, the cold air is heavy and sinks, vertical convection of the air is formed, the wind speed inside the higher tower is gradually increased, and the hotter the air is, the stronger the vertical hot convection is, and the larger the wind speed is; and the stable wind speed is formed, and the wind driven generator on the top is driven.

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 ...

AI Technical Summary

Problems solved by technology

The utilization rate of equipment is low, which causes losses to production;

[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
