提出了一种基于 SVC 的电力系统阻尼控制器的新颖设计技术。控制器尝试将所有植物杆放置在 s 平面上的指定区域内，以保证所需的闭环性能。使用霍洛维茨的定量反馈理论 (QFT) 可以设计固定增益控制器，尽管在正常运行过程中设备参数发生很大变化，该控制器仍能保持其性能。该稳健控制器的性能已在配备中点 SVC 的单机无限总线系统上进行了评估，结果显示与稳定器的预期性能一致。
A novel design technique for an SVC based Power System Damping Controller has been proposed. The controller attempts to place all plant poles within a specified region on the s-plane to guarantee the desired close loop performance. The use of Horowitz's Quantitative Feedback Theory (QFT) permits the design of a fixed gain controller which maintains its performance in spite of large variations in the plant parameters during its normal course of operation. The performance of this robust controller has been evaluated on a Single Machine Infinite Bus system equipped with a mid point SVC and the results are shown to be consistent with the expected performance of the stabilizer.
