ABSTRACT:
This paper
presents the design of a non-linear controller to prevent an electric power
system losing synchronism after a large sudden fault and to achieve good post
fault voltage level. By Direct
Feedback Linearization (DFL) technique robust non-linear excitation controller
is designed which will achieve stability enhancement and voltage regulation of power system. By utilizing
this technique, there is a possibility
of selecting various control loops for a particular application problem. This
method plays an important role in
control system and power system engineering problem where all relevant
variables cannot be directly measured. Simulated results carried out on a
single machine infinite bus power system model which shows the enhancement of
transient stability regardless of the fault and changes in network parameters.
