Abstract
The excitation control of synchronous generator in a single machine to an infinite
bus (SMIB) power system is very important to improve the stability modes of
power system. In addition to the usual or conventional excitation control techniques
and speed governors, other devices proved its effectiveness to enhance better
system stability like power system stabilizers (PSS) and static VAR compensators
(SVC). In this paper, the PSS is used as an additional device to improve the SMIB
power system stability. Two out of different control strategies were used; a
conventional control technique (PI controller) and a linear optimal controller
(LOC). A comparison between both types of PSSs was stated. The contribution of
this paper is the design and application of an optimal-PSS and a PI-PSS to a
synchronous generator connected to an infinite bus power system.
