This paper presents a new approach to derive an energy integral based on an Equivalent Mechanical Model (EMM), which is developed by introducing imaginary springs for line resistances. The proposed EMM shows that phasor currents and voltages are directly analogous to the two-dimensional force and displacement vectors, respectively. Through rigorous energy analysis of the proposed EMM, an exact energy integral expression is derived for multimachine systems, and several useful theorems are developed to derive an energy integral for power systems with detailed generator models. the energy integral exactly reflects the internal resistance, saliency and flux-decaying effects of the generator. Finally, an illustrative example is given for a multimachine system adopting the Eq’-model for generators, which shows that the consideration of a detailed generator model does not aggravate the complicity of the direct method of stability analysis in multimachine systems.
