摘要： Shading by clouds can affect the amount of flux on a heliostat which in turn can affect the energy generated by the solar device. Real-time monitoring of clouds shading is necessary for efficient operation of the entire solar power system. The output of a photo-sensitive panel attached to a heliostat may be measured in direct unhindered sunlight and at a first orientation. The output of the photo-sensitive panel may then be predicted for a second orientation. Upon measuring the actual output of the photo-sensitive panel at the second orientation, a communication function may be performed when output measured at the second orientation of the panel is below or above the predicted output. A reduced-insolation event is indicated by lower-than-predicted output at the second orientation. Upon indication of a reduced-insolation event, the heliostats may be controlled, i.e., the aiming directions for one or more of the heliostats may be changed.

摘要： Paint formulations having a high absorptivity with respect to solar radiation are disclosed herein. The disclosed paint formulations are also thermally and mechanically durable, thereby enabling the paint formulations to be used on components in solar thermal applications where exposure to high temperatures and environmental conditions may be an issue. The paint formulation can include an oxide-based pigment, an organic binder, one or more additives, an inorganic filler, and/or an organic solvent. The pigment can have a relatively high absorptivity with respect to light having a wavelength in the range from 250nm to 3000nm. Curing of the paint formulation can irreversibly convert the organic binder into an inorganic binder.

摘要： Insolation can be used to heat a solar fluid for use in generating electricity. During periods of relatively higher insolation, excess enthalpy in a superheated solar fluid can be stored in a thermal storage system for subsequent use during periods of relatively lower insolation or at times when supplemental electricity generation is necessary. Enthalpy from superheated solar fluid can be transferred to the thermal storage system so as to heat a storage medium therein, but the enthalpy transfer can be limited such that the superheated solar fluid does not condense or only partially condenses. The remaining enthalpy in the de- superheated solar fluid can be used for other applications, such as, but not limited to, preheating the solar fluid for an evaporating solar receiver, supplementing the input to a superheating solar receiver, industrial applications, resource extraction, and/or fuel production.

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： Embodiments relate to methods and systems for wireless communications in a large facility which may be an industrial, military or other facility. By placing a higher density of access points in regions close to the facility border, communication interference may be mitigated. A method of mitigating interference between an access point and a client in a wireless communication system located in a facility, may include in a first section of the facility, deploying a first plurality of access points such that each of the access points is a first distance from its neighbor. In a second section of the facility, a second plurality of access points can be deployed such that each of the access points is a second distance from its neighbor. The first distance is greater than the second distance, and the second section of the facility may be closer to a perimeter of the facility.

摘要： A solar receiver can include a row of vertically extending tubes, which may receive reflected solar insolation on the outer surface facing the heliostat field. One or more tubes arranged at the end of the row in the receiver can have an additional portion of its outer surface exposed to reflected solar insolation due to its location at the end of the row. This increases the amount of heat being delivered to these endmost tubes. Efficiency of electricity generation using a solar power generation system may be affected by working fluid temperature. The temperature of the working fluid exiting the solar thermal receiver should be uniform at each of the tubes comprising the receiver. As such, a tube can be attached to an inlet header at the edge of the receiver and can be attached to the outlet header at a distance away from the edge. Another tube of the thermal receiver can be attached to the inlet header at a distance away from the edge and then directed toward the edge of the receiver such that it becomes the outermost tube.

摘要： Support members for heliostats (or other components installed in a field) can be hollow and thin- walled, for example, to reduce construction and/or material costs. However, such support members may be relatively fragile and susceptible to buckling or other damage when driven into relatively rocky and/or hard-packed soil using pile-driving. To avoid damaging the support members, the soil may be pre-conditioned to loosen the soil prior to insertion of the support member therein. An auger can drill a hole in the soil and then be reversed such that soil remains in and/or is subsequently re-introduced into the hole after removal of the auger, thereby leaving a substantially loosened column of soil in the hole. Vibration hammering can cause temporary liquefaction of the soil around the support member to insert the support member into the column of soil while reducing the potential for damage to the support member.
