Abstract: Prototype tests were conducted in hydro-power plants at Garrison and Oahe Dams to evaluate results of a comprehensive digit al computer study by others on the entire problem of power plant transients and to determine the extent to which actual operation corresponded to the design. Measurements of power plant transients for different plant loadings, and instantaneous pressure values at a number of locations in the power tunnel, the surge tank system, turbine spiral case, and draft tube were obtained simultaneously with instantaneous values of tunnel flow velocity, reservoir and tailwater elevations, turbine speed and gate opening, power output, and other elements (including governor system). Pressure and water level measurements were made with electrical pressure transducers, velocities were measured with pressure transducers mounted in probes projecting into the flow and connected to pitot-static tubes on cross struts in the penstock, and mechanical and electrical values were obtained with appropriate transducers. Measurements were recorded on about 90 channels of oscillograph and magnetic tape recorders, and digitized for use in the digital compute! analyses. Detailed descriptions are given of the instrumentation, test conditions, and procedures used to obtain the measurements. Examples are given of some of the test data. Results of the data analyses will be reported by others. NOTE: This file is large. Allow your browser several minutes to download the file.
