Acoustical measurements of DOE/NASA MOD-0 wind turbine at Plum Brook Station, Ohio
This report documents the evaluation of low-frequency acoustic emissions associated with the operation of the DOE/NASA MOD-0 wind turbine generator located at Plum Brook Station, Ohio. These measurements were taken as part of a joint SERI/NASA Brook Station, Ohio. These measurements were taken as part of a joint SERI/NASA effort to study acoustic noise generation by utility-sized wind turbines. The machine-operating conditions closely simulated the operation of the larger DOE/NASA MOD-1 wind turbine installed near Boone, NC, in both its design downwind configuration and theoretical upwind mode. Measurement results indicated that acoustic impulses characteristic of the MOD-1 turbine were detectable only with a downwind configuration and a 35-rpm rotor speed, a situation which parallels a 23-rpm rotor speed operation on the MOD-1. Under the available meteorological conditions, no impulses were detected during downwind 23 rpm or by wind-induced noise, indicating a severe limitation of the microphone configuration used in these tests.
