NONLINEAR MATHEMATICAL MODEL OF HYDROELECTRIC POWER PLANT

Sa？etak Mathematical and simulation models enable hydroelectric power unit dynamic behavior analysis using computers. In this paper, nonlinear mathematical models of all elements in hydroelectrical power plant are detailed described. Basic elements of hydroelectric power unit are water supply tunnel, surge tank, penstock, water turbine and synchronous generator. If we want more credible simulations models and calculation results, we have to use nonlinear differential equations. Using these nonlinear differential equations, a simulation model was developed for Zakucac HPP
