Generator-models of different order
Information
The example illustrates the difference in dynamic behaviour between low- and high-order generator models.
A common 3-phase short circuit occurs at 100 msec, cleared after 300 ms.
Compare for example:
.generator.i current .generator.tau torqueof turbGen1 and turbGen2.
The high order model exhibits fast damping of torque-oscillations due to the damper windings. See also damper currents i_rd, i_rq (protected).
