Simulation Models of the Hydro Power Plants in Macedonia and Yugoslavia
Power Tech Conference Proceedings, 2003 IEEE Bologna(2003)
Abstract
In hydro power plants of Macedonia (FYROM) and Yugoslavia (YU) there is a very high interest in investigations concerning the static and dynamic behaviour of the units for the most frequent events that could occur. This contribution presents the most important steps for the reality oriented creation of mathematical models of hydro power plants which can be used for such investigations. Therefore in the investigated hydro power plants "Vrutok" (FYROM), "Zvornik" (YU), "Tikves" (FYROM) and "Bajina Basta" (YU) measurements were performed to obtain step response time signals of all important functional parts of the plants to be able to identify the most important parameters of the mathematical model. Using the least-square-method with the Matlab-software it was possible to identify all the necessary parameters of the mathematical models. Using the same measured input signals the response from the developed mathematical models show nearly the same behaviour as the real power plants.
