An operating model of a small electric power system grid has been deve
loped. The power system generators are predominantly gas turbine-drive
n and the turbines and generators are all modeled according to the IEE
E recommended models and in some cases, by models as given by various
turbine manufacturers The system model was then tested on the digital
computer for various load changes. Using a developed personal computer
-based data acquisition system, various operational load changes were
made on the power system and the transient effect on the power system
was measured. These changes were then used as inputs into the computer
model of the power system and the theoretical reaction of the power s
ystem was obtained. This was then compared with the measured reaction.
It was found that the theoretical and the actual results compared ver
y favorably.
