With the development of power system interconnection and with the increase of transmitted power, some cases are arising where the capacity of a transmission network is limited by steady-state stability. Analysis of steady-state stability raises some difficulties, which are different in nature from those raised by transient stability analysis. To reduce the computational difficulty associated with steady-state stability analysis, a proposed method derives an equivalent network with a reduced number of generators. In some of these methods a part of the power system is simplified so as to keep invariant the short-circuit capacity at a specific point. Nevertheless, equivalency of the reduced model obtained by these methods has not been discussed in detail theoretically. A method to reduce the number of generators is proposed assuming that the electromotive force behind transient reactance of each generator is constant.
