Control System for Kaplan Hydro-Turbine

In hydro power plants from Romania, there is a major interest for the implementation of digital systems for monitoring and control to replace the conventional control systems for power, frequency and voltage. Therefore is necessary to develop mathematical models capable to accurately describe both dynamic and stationary behaviour of the hydro units, in order to be able to implement digital control algorithms. Moreover, it is necessary to implement systems for monitoring and control of hydro power plants in a cascade system along a river, in order to optimise the use of the rivet resources. This paper presents the possibilities of modelling and Simulation of the hydro power plants and performs an analysis of different control structures and algorithms.
