针对IEEE第二基准模型system-1的次同步谐振（SSR）问题，提出了一种基于超导储能（SMES）单元的抑制方案。所研究的系统包含一个涡轮发电机组连接到一个无限的总线通过两个平行的传输线，其中之一是串联电容补偿。为了稳定所有SSR模式，提出了同步有功和无功功率调制和比例-积分-微分（PID）阻尼控制器的模态控制理论设计的SMES单元。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验证了阻尼方法的有效性。仿真结果表明，所提出的阻尼方案能够有效地抑制所研究系统的次同步谐振。>
A novel damping scheme using superconducting magnetic energy storage (SMES) unit is proposed in this paper to damp subsynchronous resonance (SSR) of the IEEE Second Benchmark Model, system-1 which is a widely employed standard model for computer simulation of power system SSR. The studied system contains a turbine-generator set connected to an infinite bus through two parallel transmission lines, one of which is series-capacitor compensated. In order to stabilize all SSR modes, simultaneous active and reactive power modulation and a proportional-integral-derivative (PID) damping controller designed by modal control theory are proposed for the SMES unit. A frequency domain approach based on eigenvalue analysis and time-domain approach based on nonlinear model simulations are performed to validate the effectiveness of the damping method. It can be concluded from the simulation results that the proposed damping scheme can effectively suppress SSR of the studied system. >
