摘要

本文介绍了应用NGH SSR阻尼方案抑制IEEE第二基准模型system-1中出现的扭转振荡的研究结果。为了稳定所有SSR模式，提出了基于模态控制理论的统一方法，设计了一种阻尼控制器，即以发电机轴转速偏差为反馈信号的动态输出反馈补偿器。为了验证所提出的控制方案的有效性，分别进行了基于特征值分析的频域方法和基于非线性模型仿真的时域方法。仿真结果表明，所提出的模态控制NGH SSR阻尼方案能有效抑制系统的扭振

Damping subsynchronous resonance using modal-control NGH SSR damping scheme. I. Single-machine study

This paper presents the results of a study on the application of the NGH SSR damping scheme for suppressing torsional oscillations that occur in the IEEE Second Benchmark Model, system-1. In order to stabilize all the SSR modes, a unified approach based on modal control theory is proposed to design a damping controller which is a dynamic output feedback compensator using generator shaft speed deviation as a feedback signal. To demonstrate the effectiveness of the proposed control scheme, a frequency-domain approach based on eigenvalue analyses and time-domain approach based on nonlinear model simulations are performed. The simulation results show that the proposed modal-control NGH SSR damping scheme can effectively suppress torsional oscillations in the studied system.<>
