  • Publication number: 20170293757
    Abstract: To enhance the security of an industrial control system, a data stream can be received from an input device via a communications network or an I/O subsystem of a computer system. All or part of the data stream can be stored in computer memory. Stored elements of the data stream can be retrieved from the memory. A set of program instructions can be executed to ascertain descriptive characteristics of the stored elements. Using a comparison with a stored normative descriptive characteristic in a database or application of an algorithm, heuristic or rule, it can be determined whether any of the descriptive characteristics are anomalous. When the existence of an anomalous descriptive characteristic has been determined, an alarm can be created, data or an alarm can be communicated to a control system or an operator, and/or the data or alarm can be recorded in a database.

  • Publication number: 20160330225
    Abstract: A method of detecting anomalies in an industrial control system includes analyzing data of correct operational parameters from at least one input device and storing the correct operational parameter or a correlation of at least two operational parameters as training data. The training data is used to train an anomaly detection system. Current operational parameters of the at least one input device are detected. The anomaly detection system then checks at least one of the detected operational parameter or a correlation of at least two detected operational parameters to detect a deviation from the training data. When the detected deviation is above or below a defined threshold, a communication function is performed. For example, the communication function is at least one of creating an alarm, communicating data to at least one of a control system and an operator, and recording the data or the alarm.

  • Patent number: 9170033
    Abstract: Images representative of cloud shadows with respect to a field of heliostats can be used to adjust operation of a solar energy system. For example, images of a field of heliostats and shadows produced by the clouds can be obtained. Additionally or alternatively, images of the sky and clouds can be obtained. The images can be analyzed to determine a shading parameter. Based on the shading parameter, an operating parameter of the solar energy system can be changed or maintained. For example, the operating parameter may include aiming directions for one or more of the heliostats. Cloud characteristics in addition to the location of the cloud shadow can be used in determining the shading parameter. Such characteristics can be used in determining if and/or how to change the operating parameter of the solar energy system.

  • Patent number: 8931475
    Abstract: Systems and methods for directly monitoring energy flux of a solar receiver in a solar energy-based power generation system include measuring infrared radiation emanating from the solar receiver. Such measurement can be achieved using one or more infrared thermography detectors, such as an IR camera. Resulting thermal data obtained by the imaging can be used to determine energy flux distribution on the receiver. A user or a system controller can use the determined flux distribution to adjust heliostat aiming to achieve a desired operation condition. For example, heliostats can be adjusted to achieve a uniform energy flux distribution across the external surface of the receiver and/or to maximize heat transfer to a fluid flowing through the receiver within system operating limits.

  • Publication number: 20140238387
    Abstract: Adherence to flux or resultant measurable parameter limits, ranges, or patterns can be achieved by directing heliostat mounted mirrors to focus on aiming points designated on the surface of a solar receiver. Different heliostats can be directed to different aiming points, and a heliostat can be directed to different aiming points at different times. The cumulative flux distribution resulting from directing a plurality of heliostats to any aiming point on a receiver surface can be predicted by using statistical methods to calculate the expected beam projection for each individual heliostat or alternatively for a group of heliostats. Control of the heliostats in a solar power system can include designating aiming points on a receiver from time to time and assigning heliostats to aiming points from time to time in accordance with an optimization goal.

  • Publication number: 20140083413
    Abstract: 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 cloud shading of at least a portion of the solar field can allow for more efficient operation of the entire solar power system. For example, diffuse solar radiation and global horizontal radiation may be measured in certain parts of the field in order to estimate the direct normal radiation at any point in the solar field. A cloud map generated based on an image taken of the cloud may be used in calculating the direct normal radiation. By knowing the amount of direct normal radiation at any point in the solar field, the solar energy system can be changed or maintained. For example, the operating parameter may include aiming directions for one or more of the heliostats.

  • Publication number: 20130239952
    Abstract: A solar energy system can be controlled and operated responsively to detected and/or predicted changes in insolation conditions. By placing an imaging aperture of an imaging device as part of an external surface of a solar receiver, an orientation of each heliostat in a heliostat field can be determined. The imaging device can be used to image at least a portion of the heliostat field based on light passing through the imaging aperture, which is proximate to, adjacent to, or at least partially within the capture area of the solar receiver so as to acquire at least one image indicating a change in a distribution of insolation levels falling on the portion of the field. Characteristics of heliostats within the portion of the field can be calculated based on the at least one image. Aiming directions of one or more can be changed based on the calculated characteristics.

  • Publication number: 20130087139
    Abstract: At least some of the heliostats can be arranged and operated in such a manner that the maintenance vehicle can pass through the solar field along conditional pathways. The arrangement and control of the heliostats to allow access to heliostats by a maintenance vehicle can enable different heliostat patterns as compared with conventional arrangements. In particular, heliostats in one section of the solar field, which may be less geometrically efficient, can be arranged at a higher density as compared to heliostat in another section of the solar field. In addition, the locations of heliostats in various sections of the field can be optimized based on ground coverage as viewed from a vantage point in the solar tower and/or revenue generation without constraining the locations to particular line or arc patterns.

  • Publication number: 20130048752
    Abstract: A maintenance vehicle for heliostats as well as heliostats within a solar field of a solar tower system can be controlled to reduce the likelihood of damage to an indigenous animal or its habitat. At least some of the heliostats can be arranged and operated in such a manner that the maintenance vehicle can pass through the solar field along conditional pathways. The arrangement and control of the heliostats to allow access to heliostats by a maintenance vehicle can enable different heliostat patterns as compared with conventional arrangements. In particular, heliostats in one section of the solar field can be arranged in a more ordered and high density pattern while heliostats in another section of the solar field can be arranged in a more disordered pattern. The density and arrangement of heliostats in various sections of the field can be optimized to improve and/or maximize solar energy production and/or revenue generation.
