The definition of generator angle is proposed in this paper. A new method to deduce generator angle by using rotor rotation signal is illustrated, which compares the phase difference between GPS timing pulse and RRS. Using only mechanical signal, the technique unfreezes limitation of zero-cross of generator terminal voltage during transient process. Automatic correction of initial generator angle is also proposed .
