Continuous Source Monitoring: the Hyatt Power Plant Generators
Abstract
We explore using the generators at the Hyatt Hydroelectric Power Plant at Oroville Dam, California as a continuous source. The generators rotate at 200 rpm and they produce a coherent signal which is observed at the Oroville (BK.ORV) broadband seismic station. The observed signal, when averaged over an hour, is typically 20+ dB at 3.33326±0.001235 Hz. The Hyatt Power Plant is constructed in a cavern the size of two football fields dug in solid bedrock in the left abutment near the axis of Oroville Dam and the BK.ORV seismic station is sited on the bedrock surface approximately 1 km northwest of the power plant. The propagation path is granite. Several data processing methodologies are explored to characterize the temporal variation in the signal from the power plant.
