Control of power systems using solid state phase shifters with energy storage function has been studied for three years from 1995 to 1997. The proposed apparatus has been named SuperSMES,which is associated with its high performances superior to SMES (Superconducting Magnetic Energy Storage). Obtained results are summarized as below.1. Prototype system composed of a 10kJoule superconducting magnet and power converters has been built and tested. Operations from starting up, power system stabilization after a fault in the power system, and recovering stored energy of the superconducting coil have been successfully carried out in a model transmission line.2. The circuit equivalent of SuperSMES has been modeled as two independent current sources. A control scheme for the power system stabilization has been derived from the model. The effect of control has been verified by digital simulation.3. A control scheme based on d-q transformation referred to the rotating frame in phase with generator terminal voltage has been developed. The validity has been verified by digital simulation and experiment. A control scheme for the two machine power system has been developed and tested by sigital simulation.4. The developed controller has been modified by estimating the required signals from the local information. In addtion, a robust and effective control scheme has been derived by applying the technique to linearize the generator power swing property.5. Simultaneous compensation of harmonic and negative sequence voltage/current with the proposed SuperSMES is possible. Especially, compensation of negative sequence voltage/current is easy due to the stored energy in the superconducting magnet.

从1995年到1997年，使用具有储能功能的固态移相器对电力系统的控制进行了三年的研究。所提出的装置被命名为SuperSMES，这与其优于SMES（超导磁储能）的高性能有关。所得结果总结如下： 1．由 10kJoule 超导磁体和功率转换器组成的原型系统已经建成并进行了测试。在某模型输电线路上，成功完成了从启动、电力系统故障后稳定到超导线圈储能的恢复操作。 2． SuperSMES 的等效电路已建模为两个独立的电流源。从该模型导出了电力系统稳定的控制方案。通过数字仿真验证了控制效果。 3．开发了一种基于 d-q 变换的控制方案，该方案涉及与发电机端电压同相的旋转框架。通过数字仿真和实验验证了该方法的有效性。制定了两机动力系统的控制方案，并通过数字仿真进行了测试。 4．通过根据本地信息估计所需信号来修改所开发的控制器。此外，通过应用该技术使发电机功率摆动特性线性化，导出了鲁棒有效的控制方案。5．使用所提出的 SuperSMES 可以同时补偿谐波和负序电压/电流。特别是，由于超导磁体中存储的能量，负序电压/电流的补偿很容易。
