针对电力系统稳定性分析中混合算法的缺点，本文推导了修正的暂态能量函数。
Corrected transient energy function ( CTEF ) , the sum of corrected kinetic and corrected potential energy func- tion , is proposed in this paper for improvitng the efficiencies of hybrid method in transient stability analysis. The main charac- teristic is that the CTEF is conservative along trajectories of a post fault system. The CTEF is derived from the motion equa- tion between the inertia centre of the critical machine group and the inertia centre of the rest system. Simulation results on the 1 0- machine New England test power system showed that the transient energy margin curves obtained from the CTEF are more suitable for estimating stability limit parameter than the ones from the traditional energy function.
