POWER SYSTEM SUMMARY REPORT
PROJECT FIELD DIVISION
A. GENERAL OPERATIONS
The plant was operated with an average release of 603 cfs through the
month. Unit 5 was operated at full load during the first half of the
month, and Unit 1 the second half. Unit 4 was used to generate partial
days. The gross generation was 1,245,000 kWh for the month, with a peak
hourly output of 2,800 kWh.
No line outages occurred during the month.
The operating staff issued a total of five clearances, hotline orders,
and switching programs during the month.
The reservoir level remained fairly constant through the month at eleva-
tion 4239.79. The total average flow was 603 cfs, all of which was used
The mean average temperature for the month was 33.7 OF, with a low of 9
OF on 5th of the month and a high of 60 OF on 29th day of the month.
Precipitation for the month totaled only .13 inch, with .06 inch
recorded on 18th day of the month.
B. POWERPLANT AND SWITCHYARD MAINTENANCE
All daily, weekly, and monthly maintenance items were completed.
Continued testing irrigation pump kilowatt-hour meters, which were due
Unit 2 governor was repaired during the month. The governor acted
erratically and hunted whenever we attempted to synchronize to the
line. The dashpot was disassembled and examined. Several new parts had
to be manufactured, including the main dashpot piston. After repair,
the governor is operating normally.
Unit 7 was returned to service after sandblasting and painting of the
scroll case, draft tube, and runner. Corrective maintenance was
performed on runner and discharge cone with molecular metal. All
electrical and mechanical maintenance items were performed, and the
unit was cleaned. The unit was ramp tested. Governor pump-up time was
dramatically improved by rebuilding the check valve on the pressurized
governor oil pipeline.
