The
purpose of the third test case is to compare the dynamic
behaviourof the
model for thesynchronousmachinewith
its wholecontrolin
operation during and after a three-phaseshort-circuitbyanalysingthe
terminal voltage, the
excitation voltage inside thegenerator,
the active and reactive power of thesynchronous
machine as
wellas
speed.
At the
event-time
aboltedthree-phase
short circuit occurs at thehigh-voltage
side of theunit transformer.
After the fault duration of0.1
s theinitial
system conditionsarerestored.
The results obtained match perfectly the results presented in the
report.
