Implementation of process flow measurements in pressure pipelines in a hydropower plant
Sažetak
The paper presents the implementation of process measurements of the volume flow in the penstock of a hydropower plant. Based on this data, the operating performance of the individual units is regulated. Furthermore, defects or cracks in the penstock itself can be detected. Furthermore, the reasons for installing flow metres are described and the applicable standards and regulations are presented. The installation of sensors and control units as well as their parameterisation are shown. Finally, a comparison of the applied flow measurement methods is given with a graphical presentation of the measurement results.
