本文提出了一种用于电力系统稳定的超导储能与串联相位补偿器的组合控制器。通过使用串联补偿器，超导磁储能系统能够在短路故障期间吸收发电机加速功率。此外，故障电流受到能量吸收以及串联Transformer的漏抗的限制。提出了一种适用于串联结构超导储能系统的新型发电机摆度阻尼控制方案。数值计算结果表明，该方法对于提高电力系统稳定性和故障电流限制具有显着的效果。
In this paper, a combined controller of a superconducting magnetic energy storage (SMES) with series phase compensator for the stabilization of a power system is proposed. By the use of a series compensator, the SMES becomes capable of absorbing the generator accelerating power during a short circuit fault. In addition, the fault current is limited by the energy absorption as well as by the leakage reactance of a series transformer. A new control scheme for damping control of the generator swing has been proposed that is suitable for a SMES with series configuration. Some numerical results demonstrate significant effectiveness for enhancement of power-system stability and fault-current limiting.
