Water level control system for a low head run of river variable speed small hydropower plant
This paper presents part of the work carried out within the framework of a research project entitled Application of variable speed and intelligent control technologies to hydropower generation. Specifically, it is focused on the activities performed in order to achieve one of the main objectives of the project: the design of a water level control system for a low head run of river variable speed small hydropower plant. A speed based water level control system has been implemented in a laboratory plant and manages successfully to control the water level in the head pond. In addition, a model of the control system has been developed using Matlab Simulink(r) the validity of which has been verified by comparing experimental measurements with simulations results.
