ABSTRACT:
This document has been prepared to provide visibility into the various elements of the testing which comprises the pre-operational testing activity and interfaces required as part of the startup and acceptance testing. Martin Marietta shall provide technical inputs, personnel, software corrections and hardware replacement parts as necessary to participate in the plant integrated acceptance testing. Collector Subsystem Integrated Acceptance Testing will begin about 3 months prior to turbine roll and continue until full power operation is achieved and final acceptance of the Collector Subsystem is granted by STMPO.… (mais)

ABSTRACT:
Includes documentation related to the Collector Subsystem Optical Performance Test Procedure 118.

Objectives of this test are as follows:
1.1 Demonstrate the heliostat beam quality by taking beam quality data with the BCS. Beam quality data, shall be taken at two different times per day for each heliostat.

Beam quality data for a group of ten heliostats at a given time will be combined as follows to yield a "composite beam shape" for the group:
- The centroids of each beam shape will be superimposed by the BCS.
- The flux values at each BCS grid point will be numerically summed.
- The summed fluxes at each point will be divided by ten.
The "composite beam shape" for each group of heliostats will be assumed to represent the beam shape of a single heliostat in the group and will be analyzed using HELIOS to ASSESS compliance with the beam quality specification over the operating temperature range.

1.2 Demonstrate that the beam centroid tracking error for each heliostat is within the tracking error specification. Beam centroid tracking data shall be acquired using BCS. Tracking error data for each heliostat will be compared with the specification value of the RMS error.… (mais)

ABSTRACT:
This report summarizes the operational activities and highlights maintenance work that was performed during the month of July, 1987. In addition, it presents plant statistics and a monthly operation and maintenance cost summary.

Solar One operated 2,029.44 MWh (gross) and 1,534.96 MWh (net) during 255.20 hours of on-line operation in the month of July 1987. The plant produced 22.62% MWh (net) more than the previous July record. July 1987 and June 1987 were the second and third best power production months respectively, of the five-year test program. Solar One incurred 67.83 weather outage hours and was down for 411.50 hours for scheduled and unscheduled maintenance. During the month. the plant set four power production milestones; (a) thirty-eight consecutive days of operation (b) maximum power production week (c) maximum weekly operating time and (d) maximum power production day.… (mais)
