Conceptual design of a fixed-pitch Wind Turbine Generator system rated at 400 kilowatts. (Final report)
This report covers the design and cost aspects of a fixed-pitch, 400-kW Wind Turbine Generator (WTG) concept. Goal of the study was to achieve improvements in reliability and cost reductions with fixed-pitch operation and by incorporating recent advances in WTG technology. The specifications for this WTG concept as supplied by Lewis were as follows: (1) A fixed-pitch, continuous wooden rotor was to be provided by the Gougeon Bros. Co. under NASA contract. (2) An 8-leg hyperboloid tower that showed promise as a low cost structure was to be used. (3) Only commercially available components and parts that could be easily fabricated were to be considered. (4) Design features deemed desirable based on recent NASA research efforts were to be incorporated. Detailed costs and weight estimates were prepared for the second machine and a wind farm of 12 WTG's. The calculated cost of energy (COE) for the fixed-pitch, twelve-unit wind farm is 11.5 cents/kW-h not including the cost of land and access roads. The study has shown feasibility of fixed-pitch, intermediate power WTG operation. To achieve a competitive COE, further reductions in cost and increases in energy production are needed and possible.
