摘　　要：本文研究采用奇异摄动原理进行电力系统动态仿真计算。在隐式积分法中,新算法可以棒代牛顿迭代法同时求解差分方程和电力系统网络的代数方程,从而大大提高电力系统动态仿真的计算速度,同时可保证足够的精度。文中对同步发电机和两种典型模型的仿真计算结果证明了这一点。Application of the principle of singular perturbation to the simulation of electric power system dynamics is studied in this paper. The proposed method is used in place of the Newton' s method to solve simultaneously the difference equations and algebraic equations in implicit integration techniques.It is much faster than Newton's method per step when step length is proper. At the same time, this method also has high accuracy.
