| 摘要: |
| 应用正规形理论求电力系统在主导不稳定平衡点处的局部稳定和不稳定流形，首先要将电力系统的运动方程的泰勒展开用矩阵表示。研究了电力系统运动方程泰勒展开式的特点，正是这些特点使得电力系统运动方程的泰勒展开式得以用矩阵表示，具体推导了四阶泰勒展开式中各矩阵元素的表达式。 |

| Abstract: |
| The movement equations of power system should be expressed first in matrix formula-tion before the calculation of stable and unstable manifolds on a controlling unstable equilibrium point in application of normal form theory.The characteristic of Taylor series for a power system is studied,based on which the movement equations could be written in matrix formulation.The detail expressions for each element in these matrices of fourth Taylor series are derived.The research fund for the doctoral program of higher education(RFDP-98069814). |
