The Design of Control Systems for Hydraulic Turbines

In hydro power plants from Romania, there is a major interest for the implementation of digital systems for monitoring and control replacing the conventional control systems for power, frequency and voltage. Therefore is necessary to develop mathematical models capable to accurately describe both dynamic and stationary behavior 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 optimize the use of the river resources. This paper presents the possibilities of modeling and simulation of the hydro power plants and performs an analysis of different control structures and algorithms
