Design of power system stabilizer for Al-Umra power plant

الملخص EN

Design of a power system stabilizer for Al-Umra power system is proposed.

A linear model for the power system is presented and analysed.

The eigenvalue analysis of the model has shown the existence of an unstable mechanical mode.

To overcome this instability problem, a power system stabilizer based on a lead-lag compensator is introduced.

Parameters of the proposed power system stabilizer have been chosen and tuned carefully in order to give the system an adequate performance.

Digital time simulations indicate that the stabilizer has resulted in a significant improvement in system performance.
