Disclosed is a high-deficiency solar power plant that comprises a main closed, regenerative Brayton cycle (14) that works with a supercritical fluid and at least one closed bottoming cycle which can be a Rankine cycle (15) or a Brayton cycle (16). The main Brayton cycle (14) comprises: a heat source comprising a solar receptor (1); an expander (2); an electricity generator (3); a primary heat recuperator (4); optionally, a heat exchanger (5); a secondary heat recuperator (6); a refrigerator (7); a compressor (8); and a pump (9). In a preferred embodiment, a Rankine bottoming cycle (15) is connected to the main cycle (14) by a heat exchanger (5), while a Brayton bottoming cycle (16) is connected to the main cycle (14) by the primary heat recuperator (4). |
