Abstract

The paper presents the implementation of the automation of existing measuring points by installing vibrating wire piezometers in the inlet and outlet tunnels of the hydropower plant. This achieved automatic recording and display of the data on the monitoring system so that the measuring points no longer have to be visited to read the measured values manually. The process measurements of the uplift pressures at the base of the dam allow the condition of the injection curtain to be monitored and the permeability of the dam to be checked in real-time, which is extremely important for the stability of the structure. This paper describes the functionalities and installation of all components of the measurement system. It also analyses the measurement data with a graphical representation of the measurement data to achieve optimal system operation.
