Solano MOD-2 wind turbine: operating experience, September 1984-August 1985. Final report
Pacific Gas and Electric (PG and E) is operating and maintaining a 2500 kW MOD-2 wind turbine in Solano County, California. The wind turbine is an upwind machine with a 90 meter rotor diameter. To improve the understanding of wind turbine technology, the Electric Power Research Institute has sponsored a project to evaluate and document PG and E's experiences from September 1984 through August 1985. This report describes the performance of the PG and E wind turbine. The wind resource characteristics such as wind speed and direction were measured at the meteorological tower near the wind turbine. These data were used as representative of the turbine's wind resource after doing a wind speed and direction correlation between the wind turbine and the meteorological tower. The Solano MOD-2's performance was determined by comparing the actual output versus the manufacturer's predicted output for certain wind speeds. There have been several modifications made to the wind turbine. In 1984, the wind turbine had to be derated to 2200 kW due to overcurrent relay trips during gusty wind conditions. Another modification occurred in March 1985, when the wind turbine's pitch control system was revised and as a result, the machine was upgraded from 2200 kW to 2500 kW. To date, this modification has improved the reliability of the machine during gusty wind conditions and also increased the energy output. The wind turbine's maintenance items were recorded so that possible improvements could be incorporated to reduce future repair work.
