Abstract

Hydroelectricity is an important component of world renewable energy supply and hydropower remains a major source of electricity generation due to its environmental friendly nature. This paper aimed at modeling and simulating hydropower plant with a view of increasing the efficiency and stability of the generating station. The hydropower plant model was developed using Matlab/Simulink software. The designed model comprises: Hydraulic turbine (PID governor, servomotor and turbine), Synchronous generator and an excitation system. The dynamic response of the system to the disturbances on the system network was studied. A three phase fault was introduced in the SHPP model at 0.1 sec and cleared at 0.2 sec. The simulated result shows that the generated voltage quickly regained its stability on the removal of the fault, the stator currents went into transient after the fault was cleared and become stable at 0.4 sec. The excitation voltage also regains its stability but it was slower and the speed of the rotor was out of stable after the occurrence of the disturbance on the system. The simulated result shows an improvement in the static and dynamic behavior of SHPP and an increase in the generating performance of the generating station.
