Abstract :
This paper establishes the linearized Phillips-Heffron model of a power system installed with a STATCOM (static synchronous compensator) and demonstrates the applications of the model in analysing the damping effect of the STATCOM and designing a STATCOM stabilizer to improve power system oscillation stability. Both cases of single-machine infinite-bus and multi-machine power systems are studied and an example power system is presented, which shows the negative damping influence of a STATCOM DC voltage regulator on power system oscillations and effectiveness of STATCOM stabilizer superimposed on STATCOM AC voltage regulator to counter-attack the negative damping effect.
