本文提出了一种选择线路补偿装置、晶闸管控制串联电容器（TCSC）和传统固定串联电容器的最佳配置的框架，以降低网络中次同步谐振（SSR）的风险，同时维持所需的电力传输。本文开发的方法基于 SSR 的稳健风险评估，考虑了次同步谐振的严重性及其发生的概率。先前开发的次同步谐振风险指数用于评估次同步谐振的严重程度。线路停电模型用于确定可能导致次同步谐振的意外事件的概率。事实证明，在 TCSC 参与相对较少的情况下，即使采用最基本的控制，对线路进行串联补偿，也可以成功管理 SSR 的风险。
The paper proposes a framework for the selection of optimal configuration of line compensation devices, thyristor controlled series capacitors (TCSC) and conventional fixed series capacitors, for reducing the risk of subsynchronous resonance (SSR) in the network while maintaining required power transfer. The methodology developed in the paper is based on the robust risk evaluation of SSR that takes into consideration the severity of subsynchronous resonance and probability of its occurrence. The subsynchronous resonance risk index developed previously is used to assess the severity of subsynchronous resonance. The line outage model is employed to determine the probability of contingencies potentially leading to subsynchronous resonance. It is demonstrated that with relatively small participation of TCSC, even with the most basic control, in series compensation of lines, the risk of SSR can be successfully managed.
