Description: This paper discusses the impact of HVDC on
Power System Stability and proposes a new control mechanism
based on Fuzzy set theory to augment dynamic performance of
a multi-machine power system. To have good damping
characteristics over a wide range of operating conditions,
deviations in speed and acceleration of the machines are chosen
as the input signals to the fuzzy controller. These input signals
are first characterized by a set of linguistic variables using fuzzy
set notations .The fuzzy relation matrix allows a set of fuzzy
logic operations that are performed on controller inputs to
obtain the desired output. The effectiveness of the proposed
controller is demonstrated by a multi-machine system example.
The performance of this fuzzy controller, in comparison to the
conventional fixed gain controller, demonstrates the efficacy of
this new fuzzy PID controller.
