Research has shown that the parameters of automatic voltage regulators (AVRs) and synchronous generators can be estimated from on-line measurements acquired while perturbing the automatic voltage regulator reference signal with a pseudo-random binary sequence (PRBS) signal. The technique has, however, been tested mainly for small round rotor machines under laboratory conditions. This paper presents field experience in applying PRBS perturbations to a 133 MVA hydro-generator to obtain data for verification of the technique for larger generators.
