<p>It has been determined that the transfer function of a synchronous dynamoelectric machine connected to an electric system through a transmission line contains complex roots in its numerator and denominator. This transfer function describes the dynamic relationship between deviation of the terminal voltage of a synchronous dynamoelectric machine from the desired (reference) value and a deviation in the field voltage of that machine. The above-mentioned complex root function of the total transfer function of the machine deleteriously affects the dynamic and transient characteristic and stability of the machine. Accordingly, a compensating network is utilized to modify the field voltage in such a fashion that the effect of the complex root function on the relationship between the field voltage and the terminal voltage is minimized. Such a compensating network may be located at various places in the excitation circuitry of the dynamoelectric machine and may be appropriately modified as required by the characteristics of a given machine.</p> |
