Sažetak
Procedure to estimate parameters of synchronous hydro-generator (18 MVA)from sudden short-circuit measurement data is presented. Test performed was under small and slow speed variation and reduced excitation current. Data were collected in the form of sampled time series of measured armature voltage and currents prior to and during the sudden short-circuit test. Neither the rotor speed nor the angle between rotor and stator were measured. Detailed method of initial and final estimation of parameters were also appraised (Prony's method and constrained minimization technique) considering behaviour of the rotor angle and speed during the test.
