摘要： A concentrating solar system has multiple receivers, in some embodiments mounted on multiple towers, on which solar energy is concentrating using heliostats. At least some heliostats are controlled such that they may direct energy onto different receivers to achieve any of various control goals, such as temperature or flux uniformity of the receiver. In preferred embodiments, the receivers or receiver portions are fluidly connected in stages such that there are high temperature targets, e.g., superheated receivers or portions, and low temperature targets, e.g. evaporating receivers or targets. By doing so, it is possible to selectively control heliostats to track for directing energy on the targets to, for example, achieve temperature uniformity of the high temperature target by selecting heliostats for that control goal under varying circumstances.

摘要： The invention provides receivers which can be used to heat a working fluid to high temperature. In preferred embodiments, concentrated solar radiation is received and converted to heat at varying depths in the receiver such that multiple layers of surface are used to heat the working fluid. In addition, the depth-loading configuration helps to trap received heat to reduce radiant thermal loss.

摘要： A solar energy conversion system may include a receiver with a first heat transfer fluid channel having at least two opposite sides. Each side may present an external surface facing in a direction opposite to that of the external surface of the other opposite side. Each side may be configured to contact a heat transfer fluid carried in the first heat transfer fluid channel. A heliostat field may be configured to direct solar energy to each of the at least two opposite sides during the course of a day such that a thermal stress tending to bend the channel remains below a specified level.

摘要： The disclosed subject matter relates to methods and systems for operating a solar steam system in response to a detected or predicted reduced insolation condition (for example, sunset or a cloud condition). In some embodiments, for a period of time, enthalpy stored within a solid material of a conduit via which steam travels en route to a steam turbine is used to heat the steam to drive the turbine. In some embodiments, a net migration of heliostats away from the steam superheater is carried out in response to the detected or predicted reduced insolation condition.

摘要： Methods, apparatus and systems for operating a solar steam system in response to a detected or predicted reduced or impending reduced insolation event are disclosed herein. Examples of transient reduced insolation events include but are not limited to cloud-induced reduction in insolation, dust-induced reduction in insolation, and insolation events caused by solar eclipses. In some embodiments, in response to the detecting or predicting, steam flow is regulated within the solar steam system to reduce a flow rate into a steam turbine. Alternatively or additionally, one or more heliostats may be responsively redirected onto a steam superheater or steam re-heater.
