An analytical method of parameter estimation for the synchronous generator based on dynamic behavior evaluation is proposed in this paper. For this purpose, based on the concept of performance deviation of generator with respect to change of parameters, this paper proposes a deviation index showing the effect of change in each parameter on output variables of generator such as active, reactive and apparent powers, rotor angle, terminal voltage and armature current. In other words, the bigger value of deviation index for an output variable with respect to a specific parameter shows better estimation of parameter from that output variable. In fact, the deviation index represents estimation of each parameter within the change in dynamic behavior of generator. The proposed concept and approach is demonstrated on a test system with 25 buses and 12 machines test system.
