Abstract [en]

This project describes the design and assembly of the power electronic and control system for variable speed control of a micro scale hydro power station in Sweden. The turbine is a new type of integrated turbine-generator unit, called Turbo, designed by prof. Urban Lundin at Uppsala University. Power electronic components was dimensioned, purchased and assembled.

The projects purpose is to create an installation for testing and evaluation of Turbo and the main goal was to determine Turbos optimal rotational speed.

A commercial 20 kW solar power inverter from Fronius was used and it was controlled using LabVIEW and communicating through the serial protocol Modbus. To control the rotational speed of the generator a PI-regulator with negative feedback was used and controlled from LabVIEW. Test results shows a functioning system where the inverter is to slow to work in an optimal way. This is likely due to the fact that solar power inverters doesn't have to regulate as fast as inverters designed for hydro- and windpower.

When testing the integrated turbine generator on site it didn't rotate and final tests could therefore not be completed. This might be because of a bearing that is not properly designed and further research on the area must therefore be completed before determining the optimal rotational speed.
