| 摘 要： | 在对电力系统动态方程进行泰勒级数展开的基础上,运用normal form理论推导出其3阶解析解。分别对单机无穷大系统和2区域4机系统进行了仿真,通过在时域和频域定义的两个近似度指标对比分析线性解析解,2阶解析解及3阶解析解在分析电力系统受扰后的动态特性精确性。并且应用prony算法对仿真结果进行定量分析,检测到了数值积分解中高阶复合模态的存在。从而,验证了推导的3阶解析解对受扰后系统进行分析的有效性。 |

| Abstract: | Based on Taylor series expansion of the equations the third order analytical solutions of power system dynamical equations is derived by using normal form theory.In order to verify the theory proposed in this paper,numerical simulations are performed on a single machine infinite bus system and a four-generator two-area system.The linear,the second order,and the third order,solutions are compared,with two proximity indices defined in time domain and frequency domain,respectively.And Prony analysis is perform... |
