This is a Single-Machine-Infinite-Bus (SMIB) system containing disturbances on the excitation system reference, in generation unit connected to bus 1. These disturbances allow the user to observe dominant dynamics from the excitation system that can be used to identify certain set of parameters.
Simulate the system for 20 seconds. Variables of interest are:
sT5B.ECOMP
sT5B.EFD
Note that the disturbance changes the measured voltage ECOMP
, leading to a response from the excitation system control, which increases the output EFD
.
This disturbance shows the dynamic response of the excitation system and, therefore, enables parameter identification procedures to be run.
