On the basis of thermal energy storage technology and dual-generator co-generation ideas,a novel solar tower thermal power co-generation system was proposed.The system applies two thermal energy storages and two turbines.In this system,the high temperature gas turbine is combined with the high tem-perature thermal storage,and the steam turbine is combined with the medium temperature thermal storage. The two turbines not only can work together,but also can run separately for a short time.The estimation results show that,peak efficiency of the tower solar thermal power system is up to 20.5%,and the annual average power generation efficiency is 1 3 .3 7%.This system can take full use of solar heat,enhance power generation efficiency,and reuse the waste heat.
