近年来，含风电场的串联补偿电网的次同步谐振问题引起了人们的广泛关注。为了更好地理解这种系统的本质，本文对基于双馈感应发电机（DFIG）的风力发电系统与串联补偿电网互联进行了模态分析。在Matlab/Simulink中建立了系统模型。该文件的主要贡献包括：1）四种系统模式的识别（SSR、超同步、机电和轴模式），2）研究各种参数和操作条件对这些模式的影响，以及3）使用模态分析来预测系统的动态性能，并且通过时域仿真结果来确认这种预测。
Interests of subsynchronous resonance (SSR) in series compensated electric networks with wind power penetration have arisen recently. To better understand the nature of such systems, modal analysis of a doubly-fed induction generator (DFIG)-based wind energy system interconnected with a series compensated electric network is conducted in this paper. The system model is built in Matlab/Simulink. The major contributions of the paper include: 1) identification of the four system modes (SSR, supersynchronous, electromechanical, and shaft modes) of a DFIG-based wind farm interfaced with a series compensated network, 2) investigation of the impacts of various parameters and operating conditions on those modes, and 3) prediction of the dynamic performance of the system using modal analysis and confirmation of such prediction via time-domain simulation results.
