A Method for Determining the Response of a System to Loss of Excitation

Because of several loss-ofexcitation operations, it became necessary to develop a method to study the effect that loss of excitation on one generator would have on other generators on a system. Methods described in the literature were suitable for solving the single-machinie infinite-bus case only. The purpose of this paper is to describe another method involving modification of the techniques used in solving the transient stability problem. This method, which produces results similar to those obtained by other methods, is useful in studying the effect of loss of excitation on a multimachine system.
