This paper applies slow coherency theory to identity electric power system generator.In this method,since the location of faults does not influence the low frequency property,the complexity encountered in settling the problem with ordinary coherency identification methods is avoided.A coefficient of buffer processing is proposed,which can measure the influence from fault point to external system.By this conception,a buffer equivalent area is then established.It gives more accurate equivalence in the external system.The validity of the method is illustrated by using a 32 machine,126 node system.The method performs an important function in the on-line stability calculation.
