SOLAR POWER SATELLITE AND MICROWAVE TRANSMISSION FROM SPACE TO EARTH FOR GENERATING ELECTRICAL POWER
Journal Title: International journal of research -GRANTHAALAYAH - Year 2017, Vol 5, Issue 4
Abstract
A solar power satellite (SPS) is a renewable energy system that converts the sun’s energy into electricity in space and transmits it to Earth using microwaves. One of the most challenging technologies for the SPS is microwave power transmission from the geostationary orbit to the ground. The technologies for microwave power transmission have been studied for more than 40 years since the initial demonstrations in the 1960s; however, for SPS application, considerable research, especially on high-efficiency power conversion between direct current (dc) and radio frequency (RF) and on high-accuracy microwave beam control over a long range, is still needed. This paper introduces the concept of SPS and presents the technologies and issues associated with microwave power transmission from space to ground to generate electrical power.
