Transmitting Antenna System for Space Solar Power Plant

Abstract

The invention discloses a transmitting antenna system of a space solar power station. The transmitting antenna system is funnel-shaped on the whole. The transmitting antenna system is characterized in that the funnel-shaped transmitting antenna system is formed by splicing and assembling a plurality of oblique curved structure units; each oblique curved structure unit comprises a supporting frame, a photovoltaic cell layer and a transmitting antenna layer mounted at the inner side of the supporting frame, and a radiation panel layer mounted at the outer side of the supporting frame, wherein the photovoltaic cell layer is disposed on the transmitting antenna layer; and each radiation panel layer comprises an oblique curved panel, an oscillator, a phase shifter, an amplifier, a power divider and connecting cables, wherein the oscillator, the phase shifter, the amplifier and the power divider are mounted on the oblique curved panel, and the shape of the oblique curved panel is consistent with a Bezier curve. The transmitting antenna system has the advantage that by adopting the oblique curved structure units, the problem of heat radiating is solved, the power-to-mass ratio of the system is improved, the problem that the requirement on the angle of incident sunlight is strict is solved, and the difficulty of focusing system design is reduced.

Description

Technical field [0001] The invention relates to a transmitting antenna system, in particular to a transmitting antenna system of a space solar power station. Background technique [0002] In 1968, based on the development of microwave wireless energy transmission technology, Dr. Peter Glaser of the United States put forward the idea of ​​building a Space Solar Power Satellite. Space solar power plant refers to a power system that collects solar energy in space, converts the solar energy into electrical energy through photovoltaic cells, and transmits it to the ground through microwaves. [0003] In 1979, the U.S. Department of Energy (DOE) and the National Aeronautics and Space Administration (NASA) proposed the first SSPS conceptual design, which was called "1979SPS Reference System". The reference system was deployed in geosynchronous orbit (GEO) with 60 Solar power satellites, the size of each power satellite is 5km×10km×0.5km, 50km 2 The photovoltaic cell array is controlled b...

Problems solved by technology

This system has three disadvantages: first, the photovoltaic cell needs a high-power rotating mechanism to control the pointing to the sun in real time; second, the photovoltaic cell has an area of ​​50km 2 , requires a super-large supporting truss structure; third, the photovoltaic cell array and the transmitting antenna need to be connected by a super-power conductive slip ring, which is difficult to realize

However, the emission system 301 has extremely strict requirements on the concentrator, which can only receive 100% of the vertically incident sunlight, and the sunlight incident from other angles will be blocked by the radiation panel 403 to varying degrees.
