Abstract:
Development and utilization of solar power is a momentous task to be faced by new energy technology innovation around the world. The solar power tower, particularly, is of strategic importance for environment improvement and continued development of electric power industry. These advantages are bound to make it a kind of the globally important energy industry in this century. On the basis of comparing 3-type solar thermal power generation systems, both the development history and the characteristics of solar power tower （SPT） are expounded. The basic principle of SPT and the technology progress in SPT power plant are also presented. As for the SPT generation, several key techniques are analyzed specially. They are solar heliostats, receiver and high-temperature thermal storage technology. Based on the analysis of the above key techniques, it is pointed out that large-scale high-temperature thermal storage technique should be given top priority in realizing solar thermal power generation. At the same time, some basic research contents and research direction are put forward for developing SPT system in China.[著者文摘]
