POWER SYSTEM STABILIZER(PSS)
INTRODUCTION TO PSS
Needs for PSS
To extend the angular stability
A cost efficient and satisfied to solution to the
problem of oscillations conveniently done by PSS
It provides additional damping to the system
It provides the performance of excitation system

ADVANTAGES AND DISADVANTAGES
Improved damping of the system
The dynamic stability of a system is improved
Reduced power losses
Time consuming tuning of PSS
Non-optimal damping in the entire operating range.
