Considering the common characteristic of phase shifters. this paper makes the unified treatment of phase shifters in the transient stability computation. and obtains a unified form of bus admittance matrix with the effect of the phase shifter lines. The paper also combines the unified form with the expansion of high order Taylor series, and obtains a flexible and fast computation method of transient stability with unified treatment of various phase shifters.
