1. By consulting books on synchronous generator experiments, find out about and describe the methods that can be used to empirically determine the parameters of a synchronous generator.
2. During a transient in an electrical power system, the electromagnetic transient process in the electrical network is much faster than the rotor flux dynamics of the generator, so in the synchronous generator model that is used to analyze the electromechanical transient process, the time derivative of stator winding flux linkage is taken to be zero. Analyze the effect of this approximation on calculation quantity
