Summary: In the article the role of mathematical modelling is
outlined inthe analysis of active power and water level control system
ofunique hydro-electric power plants (HEPPs) and HEPPs in a cascadeas well
as in the controller design. The parallelism in processmodelling is
pointed, the goals are exposed of detailed andcomplex mathematical
modelling as well as the use of simplemodels. The basic modelling elements
of both kinds are given. Theneed is explained for system identification for
simplifiedmodel-building on the basis of process measurements for purposeof
controller design. The basic identification elements arepointed, and the
selection of adequate method is made. On thebasis of real data the
identification is carried out. Thecomparison is made between the results of
simulations using thesimple identified model and detailed model as well as
realprocess data, for the reservoir water control level of a uniqueHEPP.
Keywords: hydroelectric power plant (HEPP), cascade of HEPPs, real-time feedback control, controller design, mathematical model, diversion channel, reservoir, dynamics, simplified mathematical model, identification process, identification results, simulation results, comparison

Summary: In the hydroelectric power plant (HEPP) water level
controllerdesign, simplified and linearised process control models areused.
For the model building system, identification has beencarried out, and for
the model and the controller a verificationcontrol system has been
simulated utilising detailed and complexmathematical models.
The implemented system identification programs are described.Singular
analysis method applied to the least squares criterionis argumented.

Summary: Application programs are suggested for hydro-electric power
plants' (HEPPs') cascade control center in Varadin. The programs are
subdevided into categories: production scheduling - active power short term
plan (planning functions), operation control (operation control functions),
process simulator (study and education functions).
The process characteristics are outlined. Demands on HEPPs' cascade
management and control as part of electric power system, are pointed.
Basic algorithms are given as well as recommendations for program system
design.
Keywords: hydro-electric power plants' cascade, cascade control centre, application programs, production scheduling, operation control, process simulation, algorithms.
