In this paper a power system equivalent model is presented for power system transient stability studies.The original sub-system to be simplified is replaced by an equivalent machine and a simple fixed configuration network,. The values of the internal e.m.f. and the inertia time constant of the equivalent machine are each obtained from the weighted mean of those of the original subsystem machines, while the equivalent network configuration and its parameters are determined from the number of the terminal points and the electrical boundary conditions of the original sub-system network. In this way both steady-state and dynamic equivalent conditions are satisfied.It has been shown by simulation results that the dynamic behaviour of the simplified power system is nearly identical with the original. T his net hod will significantly reduce the computer storage and time requirments for large power system transient stability studies.
