Abstract :
AVR parameter tuning for voltage control of power system generators has generally been done with the "off-line open-circuit model" of the synchronous generator. When the generator is connected on-line and operating at rated load conditions, the AVR operates in an entirely different environment from the open-circuit conditions. This paper describes a new method for AVR parameter tuning for on-line conditions using parameter optimization technique with frequency response characteristics of linearized "on-line" system model. As the proposed method uses the on-line system model, the tuned parameters show the optimal behavior in the on-line operating conditions. Furthermore, as this method considers the performance indices that are needed for stable operation as constraints, the performance of the tuned parameter guarantees the stable operation.
