摘　　要：提出一种基于Prony算法的辨识HVDC系统传递函数的方法 ,直接从时域仿真数据或实测数据得到系统的等值线性模型 ,能够提供与特征值分析法本质上相同的信息 ,却不需要列写大规模的系统方程和建立系统的详细模型 ,为大型互联电力系统的振荡模态分析和控制系统设计提供了方便。并用HVDC系统实例研究验证了它的有效性和准确性。An approach of system model identification is presented based on Prony analysis. The equivalent linear model or transfer-function of a dynamic system can be identified from time domain simulation or measured data by using this method. The model provides the same information as eigenvalue analysis methods without using detail models or large-scale equations of the systems. Therefore it is easy to analyze the oscillation modes and to design control systems of large-scale power systems by Prony method. In addition, the identified model of a practical AC/DC interconnected system is studied. The results show the effectiveness and the accuracy of the method.
