Series-Compensated Transmission Lines (SCTLs) are widely used for connection of large scale wind power plants (WPPs) to the power system to transmit the active power generated from WPPs. However, it can lead to sub synchronous resonance (SSR) phenomena in WPPs connected with SCTLs. Also, capacitive compensation of transmission lines reduces the line impedance, which leads to increasing short circuit current level in WPPs. This study proposes the resistive bridge-type fault current limiter (RBFCL) for SSR mitigation and limiting short circuit current in WPPs connected with SCTLs. Also, its performance is compared with the static synchronous compensator (STATCOM) and thyristor controlled series capacitor (TCSC) to demonstrate the effectiveness of the RBFCL in terms of SSR mitigation. The WPP used in this paper is modelled based on an aggregated squirrel-cage induction generator (SCIG) derived by an aggregated wind turbine (WT). The PSCAD/EMTDC software and the IEEE first benchmark model are used for this study. Simulation results demonstrate that the RBFCL not only limits the short circuit current contribution of WPPs, but also effectively damps the SSR oscillations due to IGE as well as TI, when the WPP is subjected to a large disturbance.

串联补偿传输线（SCTL）广泛用于将大型风力发电厂（WPP）连接到电力系统，以传输WPP产生的有功功率。但是，它可能导致与SCTL连接的WPP中出现亚同步共振（SSR）现象。此外，传输线的电容补偿会降低线路阻抗，从而导致WPP中的短路电流水平增加。本研究提出了一种电阻桥式故障电流限制器（RBFCL），用于减轻SSR并限制与SCTL连接的WPP中的短路电流。此外，将其性能与静态同步补偿器（STATCOM）和晶闸管控制串联电容器（TCSC）进行了比较，以证明RBFCL在SSR缓解方面的有效性。本文中使用的WPP是基于聚合风轮机（WT）衍生的聚合鼠笼式感应发电机（SCIG）建模的。本研究使用PSCAD / EMTDC软件和IEEE第一基准模型。仿真结果表明，当WPP受到较大干扰时，RBFCL不仅限制了WPP的短路电流贡献，而且有效地抑制了IGE和TI引起的SSR振荡。
