BCS technical objectives and design requirements (RADL Item 3-1). 10-MWe solar-thermal central-receiver pilot plant: solar facilities design integration

Technical Report · Sat Dec 01 00:00:00 EST 1979

OSTI ID:6741860

Technical objectives and design requirements are presented for the Beam Characterization Subsystem (BCS) of the Barstow Solar Pilot Plant. The BCS acquires the data necessary to characterize the reflected beam from a heliostat or mirror module with respect to the beam size and shape, flux distribution, beam centroid, and beam power. The BCS will be used to align heliostats and provide operational support for Collector Subsystem realignment, performance evaluation, and maintenance throughout the pilot plant test period. The BCS is based on the Digital Image Radiometer measuring and recording instrument. There are 4 video cameras, each of which views an elevated target mounted on the tower beneath the receiver. The digitized intensity output of each camera is correlated with absolute intensity by a calibration procedure utilizing one or more target mounted radiometers. A simplified operational sequence of the basic BCS is presented. Performance specifications are provided for parameters to be measured by the BCS, preliminary subsystem design requirements, output data and analysis, and environmental design conditions. BCS operational requirements and procedures are presented for the overall plant and for both nominal and off-nominal conditions. The interface of the BCS with other subsystems is described. Initial requirements for the installation, checkout, and acceptance test are given. Requirements for a maintenance plan are also briefly discussed. (LEW)
