Abstract

This article introduces several kinds of thermal accumulating technologies used in solar thermal electric generation, which indicates that the steam storage is the cheapest and the most credible thermal accumulating technology, and then discusses the problems such as the connection methods of the steam storage and the calculation of the capacity of the storage. Finally, the article analyzes the run characteristics of the steam storage in the system, and educes the rules that the run time of the turbine changes with the water filling coefficient and the valve opening.
