关于串补系统SSR问题的特征分析及同步机等值模型的研究

Eigen-analysis of SSR in Series Compensated System and Study on on Influence of Equivalent Model of Synchronous Machine

以IEEE次同步谐振研究用典型系统Ⅰ为研究对象，建立了机电统一的系统状态空间方程，采用特征值分析的方法进行了次同步活振分析，并对同步电机的等值电路数学模型分别就IEEE常规模型、Canay模型对SSR研究所带来的影响作了分析对比，提出工程计算造型参考意见。

The state space equation of electro-mechanical system is established for IEEE SSR benchmark system I. SSR is analyzed by eigen-analysis method. IEEE model and Canay model are used as the equivalent model of synchronous machine respectively,and the influences of the use of different models on the study of SSR are discussed by comparison. Suggestions for engineering calculation and model adoption are proposed for reference.
