Abstract
The operation and control of electric power system highly depends on knowledge of dynamic conditions. Power plants, especially hydropower plants, have the highest impact on overall power system dynamics. Therefore, dynamic mathematical model of hydropower plant was developed in order to conduct a theoretical research of the dynamic conditions of the transmission power system during normal and abnormal operating conditions. To build the mathematical model of the hydropower plant, synchronized phasor measurements from the Phasor Measurement Units were used for a dynamic picture of a part of power system near hydropower plant. Relevant events recorded by WAM (Wide Area Monitoring) System were used for fine tune-up of the dynamic mathematical model of hydropower plant. Additional validation of the mathematical model was made by using MatLab calculations. An example of the proposed dynamic modelling was performed on reversible hydropower plant.
