The work presented herein is focusing on mitigating sub-synchronous-resonance (SSR) oscillatory torque and speed responses developed in power network equipped with series capacitor compensation as an outcome of the network perturbations. The mitigation effect of a battery-energy-storage (BES) controlled via a fuzzy-logic-controller (FLC) is explored. It is also explored accompanied by a fuzzy-bases resistor brake controlled via FLC. The IEEE second benchmark system is selected as a test grid under the MATLAB™/Simulink simulation environment. The signal utilized for the propositioned controller is the alternator rotor speed deviation. The key conclusions of this investigation are the employment of a BES in the discharging mode alone might be utilized to alleviate the SSR relative speed, and torque oscillations, the BES employment accompanied with dynamic resistive brake is supplying faster-decaying rates for the SSR oscillations in observation with the BES employment only.

电池储能和电阻制动的协调模糊操作，可减轻SSR振荡

本文介绍的工作着重于减轻由于网络扰动而在配备有串联电容器补偿的电力网络中开发的亚同步谐振（SSR）振荡扭矩和速度响应。探索了通过模糊逻辑控制器（FLC）控制的电池能量存储（BES）的缓解效果。还将探索通过FLC控制的模糊基电阻制动器。在MATLAB™/ Simulink仿真环境下，选择了IEEE第二基准系统作为测试网格。用于定位控制器的信号是交流发电机转子速度偏差。这项研究的主要结论是，仅在放电模式下使用BES可以用来减轻SSR的相对速度和扭矩振荡，
