Embodiment

[0028] The invention provides a space solar power station with energy distribution collection conversion and beam centralized control emission, which can operate in geosynchronous orbit. Such as figure 1 As shown, the space solar power plant of the present invention includes a plurality of energy collection and conversion devices 101 and beam centralized control transmitters 102. The energy collection and conversion devices 101 are evenly distributed on a circle with the beam centralized control transmitter 102 as the center of the circle. The energy collection and conversion devices 101 and the centralized beam control transmitting device 102 are relatively fixed to form a co-located satellite group. Both the energy harvesting and converting device 101 and the beam centralized control transmitting device 102 are placed on a traditional spacecraft platform.

[0029] The energy collection and conversion devices 101 are all the same, as figure 2 As shown, it mainly includes a...

Abstract

The invention relates to a spatial solar power station for energy distribution collection conversion and beam centralized control emission in the field of space technology. The solar power station comprises a plurality of independent and identical energy collection conversion devices and a beam centralized control emission device which are all placed on a spacecraft platform. The energy collectionconversion devices are evenly distributed on a circle centered on the beam centralized control emission device, are fixed in relative positions to form a co-located satellite group. The solar power station having a large overall size is converted into multiple groups of identical devices which collect and convert spatial solar power in a distributed manner, are independent of each other, and do not affect each other. Each individual device is small in size and light in weight. The spatial solar power station is not required to be assembled and spliced in orbit, thereby reducing the requirements for carrying and greatly reducing the difficulty in engineering realization.

Description

technical field [0001] The invention belongs to the field of space technology, and in particular relates to a space solar power station that collects solar energy in a distributed manner and converts it into laser light, and centrally controls and emits laser beams. Background technique [0002] The depletion of earth's energy has become a major threat to human society, and the energy consumption mainly based on fossil resources is also seriously damaging the environment on which human beings depend. It is imminent to develop renewable and pollution-free new energy sources, among which solar energy is recognized as one of the clean energy sources. Ground-based solar energy application technology is relatively mature, but due to the existence of the atmosphere, the power density of sunlight hitting the ground is less than 1 / 7 of that in space. At the same time, affected by geography, climate and weather, the power density of solar energy on the ground fluctuates greatly. Usu...
