Abstract :
A method is presented for determining the characteristic quantities and model parameters from the given frequency responses x d(js), xq(js). The curves of values measured on a large turbogenerator at standstill are used as an example. The characteristic values and model parameters are determined for various models (with four, three, and two rotor circuits in each axis) and are compared with the results of short-circuit tests and with advanced calculations
