Software/firmware design specification for 10 MW/sub e/ Solar Thermal Central Receiver Pilot Plant

Technical Report ·
OSTI ID:7146534

This Collector Subsystem Software/Firmware Design Specification exists as a stand-alone document to provide a complete description of the software and firmware employed for the operation of the 10 MWe Solar Thermal Central Receiver Pilot Plant Collector Subsystem. The software/firmware systems have the capability to allow operator control of up to 2048 heliostats in the operation of the 10 MWe Solar Thermal Central Receiver Pilot Plant at Barstow, California. This function includes the capability of operator-commanded mode control, graphic displays, status displays, alarm generation, system redundancy and interfaces to the Operational Control System (OCS), the Data Acquisition System (DAS), and the Beam Characterization System (BCS) through the OCS. The operational commands will provide for the following: (a) safe beam movement whenever automatic beam movement is required; (b) single and multiple heliostat addressing; (c) emergency heliostat movement for high-wind conditions and receiver problems; and (d) recovery for full or partial power-loss conditions. The control hardware consists of a host computer, the Heliostat Array Controller (HAC), interfaced to a group of communication controllers, the Heliostat Field Controllers (HFCs), communicating with individual processors, the Heliostat Controllers (HCs), which monitor and command a single heliostat. The system consists of two HACs and 64 HFCs with up to 32 HCs per HFC.
