Roskrepp field measurements 19.09.2017

Pressure measurements in Roskrepp hydropower plant at different operating points. The data about the generated power and generator parameters are provided by the power plant operator. Data about the water levels in the upper and lower reservoir presented in Water level at Oyarvatn.csv and Water level at Roskreppfjorden.csv, respectively are collected at 1h intervals. The pressure measurements are measured in the turbine inlet pipe and in the draft tube using pressure transducers with characteristics presented in the metadata. The guide vane opening is measured as stroke using position sensors installed on the guide vane moving mechanism. The rotation is determined using a tachometer directly on the turbine shaft.
