abstract={The small-signal stability of a power system is enhanced by damping system oscillations
by power system stabiliser (PSS). In synchronous generators driven by
reciprocating engines there are torque variations which in turn disturb the PSS
operation. This thesis investigated the current methods used to design PSS for reciprocating
engines and also the use of filters to reduce the engine torque
uctuation.
The use of torque change for testing PSS performance is also investigated. This is
done by modelling a linearised single machine infinite bus (SMIB) along with PSS2B
in Matlab as well as in Simpow software. The time and frequency domain analysis
were used to evaluate the performance of the system with and without the PSS and
notch filter. It is found that the proper tuning of PSS2B can improve the overall
damping and stability of the system. The appropriate notch filter implementation
at the frequency where the torque noise occur help to greatly attenuate the torque
noise from the engine without affecting the PSS operation and overall stability. This
also study shows that the deliberate torque change can be used for evaluation of PSS
performance at local oscillation modes.},

AB The small-signal stability of a power system is enhanced by damping system oscillations
by power system stabiliser (PSS). In synchronous generators driven by
reciprocating engines there are torque variations which in turn disturb the PSS
operation. This thesis investigated the current methods used to design PSS for reciprocating
engines and also the use of filters to reduce the engine torque
uctuation.
The use of torque change for testing PSS performance is also investigated. This is
done by modelling a linearised single machine infinite bus (SMIB) along with PSS2B
in Matlab as well as in Simpow software. The time and frequency domain analysis
were used to evaluate the performance of the system with and without the PSS and
notch filter. It is found that the proper tuning of PSS2B can improve the overall
damping and stability of the system. The appropriate notch filter implementation
at the frequency where the torque noise occur help to greatly attenuate the torque
