Tittel

Statistical approach to on site measurements in Hydro power plants

Sammendrag

Is continuous efficiency measurement of water power turbine runners at all feasible by use of clamp-on acoustic measurements of the flow rate, without applying restrictions during the testing period? This is the main question that this PhD thesis will endeavor to answer. Testing the system will have to be done as much in accordance to international standard regulations and rules as the circumstances allows. Point checks of the system with an accepted measuring method will have to be performed (thermodynamic method is the most likely method to be used for the comparison tests). To improve the measurement results quality it is highly likely that a statistical analysis models will have to be used to obtain satisfactory results. Validation of samples used for computation will be performed through statistical analysis. As for all theoretical model or analysis method, this will have to show its worth in an actual field test. The candidate will therefore test it on an efficiency measurement in cooperation with the company Norconsult. This would be one first step towards reaching the secondary goal of the thesis: Improvement of EMs in general through statistical analysis. Also, further improvements, tools to refine the acquired data, may be necessary to improve the quality of the gathered data in the continuous measurement system. A system based on Kalman Filter has been proposed. Another possible option is a model based on artificial neural network.
