Abstract
In one embodiment, a concentrated solar power system includes a solar tower, multiple solar receivers mounted to the solar tower at different vertical elevations, and a plurality of heliostats provided on the ground within a heliostat field, wherein each heliostat is configured to concentrate solar radiation on any of the solar receivers mounted to the solar tower.
Claims22
A concentrated solar power system comprising:
- a solar tower;
- multiple solar receivers mounted to the solar tower at different vertical elevations;
- a plurality of heliostats provided on the ground within a heliostat field, each heliostat being configured to concentrate solar radiation on any of the solar receivers mounted to the solar tower;
- a first heat transfer fluid configured to be heated by at least a first solar receiver;
- a working fluid configured to drive a first thermodynamic cycle, wherein the working fluid does not flow through the solar receivers;
- and
- a heat exchanger configured to transfer heat from the first heat transfer fluid to the working fluid.
4 more elements
A method for generating power, the method comprising:
- providing a solar tower to which first and second solar receivers are mounted at different vertical elevations;
- concentrating solar radiation on the first and second solar receivers using a field of heliostats;
- heating a first heat transfer fluid within the first solar receiver and heating a second heat transfer fluid within the second solar receiver, the first and second heat transfer fluids being different fluids;
- delivering the first heat transfer fluid to a heat exchanger through which a working fluid flows to transfer heat from the first heat transfer fluid to the working fluid;
- and
- delivering the working fluid to a thermodynamic power system to generate power.
3 more elements
A concentrated solar power system comprising:
- a solar tower having a first solar receiver positioned below a second solar receiver;
- a heliostat field provided on the ground, the heliostat field including a plurality of near-field heliostats and a plurality of far-field heliostats, each of the plurality of near-field heliostats and the plurality of far-field heliostats configured selectively and independently concentrate solar radiation on one of the first solar receiver and the second solar receiver depending on an intensity of solar radiation;
- and
- a control system configured to control the flow of a heat transfer fluid through one or both of the first and second solar receivers based on a temperature of the heat transfer fluid exiting a respective one or both of the first and second solar receivers to achieve a desired exit temperature to drive a thermodynamic cycle.

- a first heat transfer fluid configured to be heated by the first solar receiver to drive a first thermodynamic cycle;
- and
- a second heat transfer fluid configured to be heated by the second solar receiver to drive a second thermodynamic cycle independently of the first thermodynamic cycle.
