Abstract :
A state-space representation of a synchronous generator is established and used to analyze the transient behavior of a synchronous generator. The machine is a 2 pole, 150 MVA, 120 MW, 13.8 kV, 50 Hz generator connected to an infinite bus through a transformer and a transmission line. The state-space representation is based on a two-axis equivalent-circuit model of the generator and includes the swing equation and the voltage regulator. The two-axis representation of the infinite bus voltage is chosen as reference. A three phase short circuit is simulated at the transformer terminals. Graphic results are analyzed and compared with actual measurements and with those obtained from a finite element model of the generator. The results give insight into the electromagnetic phenomena and the state-space representation provides a platform for the analysis of control schemes to improve the stability of the generator
