Abstract

A liquid-nitrogen assisted energy storage tower type solar power plant comprises a tower, a reflector field, a heat absorber, a high temperature temperature-difference engine, a first generator, a low temperature energy storage tank, a high temperature energy storage tank, a low temperature temperature-difference engine, a second generator and a liquid nitrogen storage tank, wherein the tower, the reflector field, the heat absorber, the high temperature temperature-difference engine, the first generator, the low temperature energy storage tank and the high temperature energy storage tank form a solar power plant having energy storage functions and working during the day, and the low temperature energy storage tank, the high temperature energy storage tank, the low temperature temperature-difference engine, the second generator and the liquid nitrogen storage tank form a liquid nitrogen cooled energy storage type power plant which works during night. The liquid-nitrogen assisted energy storage tower type solar power plant improves power generating efficiency and the power generating capability during the night by utilizing nitrogen, makes 24-hour uninterrupted power supply technically possible, and eliminates the interruption of the solar power generating. The liquid-nitrogen assisted energy storage tower type solar power plant can rapidly lowers the solar power generation cost, and facilitates application and popularization of solar power generation.
