汽轮发电机组在长输电线路上串补时可能发生次同步谐振（SSR）现象。本工作的主要目的是验证门控串联电容（GCSC）的能力，以减轻SSR。在这项研究中，GCSC与IEEE第一基准模型一起进行了测试。利用交替瞬变/电磁瞬变程序进行数字仿真，验证了控制SSR的实际可能性。结果表明，即使没有特定的控制，GCSC也可以阻尼SSR。它还表明，使用一个简单的控制器，SSR以及机电振荡可以阻尼。
The subsynchronous resonance (SSR) phenomenon may occur when a steam turbine-generator is connected to a long transmission line with series compensation. The main purpose of this work is to verify the capability of the gate-controlled series capacitor (GCSC) to mitigate SSR. For this study the GCSC was tested in conjunction with the IEEE First Benchmark Model. The actual possibility of controlling SSR was verified by digital simulation using the alternative transients program/electromagnetic transients program. As a result it was shown that GCSC can damp SSR even without a specific control. It was also shown that, using a simple controller, SSR as well as electromechanical oscillation can be damped.
