Abstract

The superconductive magnetic energy store (SMES) approach to utility-load leveling has the potential for very high energy conversion efficiency and fast response to changes in load demands. It can be used to improve utility system operation economics and system stabilities. The power-conditioning circuit interfacing an SMES and a utility network consists of thyristor or gate-turn-off (GTO) device bridges of the combinations of thyristor bridges and GTO bridges. The special requirements for power-conditioning circuits are discussed, and an experimental model system for testing the performance of the proposed circuits is described. The experimental studies concern power transfer of the model system, current balance control, independent real (P) and reactive (Q) power control, online numeric P-Q measurement, and protection of the SMES system. The proposed GTO circuit topology appears to satisfactorily provide independent real and reactive power control and maintain the high efficiency and fast response properties of the SMES system.<>

超导磁能存储电源调理电路的研究

超导磁能存储(SMES)方法具有非常高的能量转换效率和对负荷需求变化的快速响应的潜力。可用于提高公用事业系统运行经济性和系统稳定性。连接中小企业和公用事业网络的功率调节电路由晶闸管或栅极关断(GTO)器件桥组成，由晶闸管桥和栅极关断桥的组合组成。讨论了功率调节电路的特殊要求，并描述了测试所提出电路性能的实验模型系统。实验研究涉及模型系统的功率传输、电流平衡控制、独立的有功(P)和无功(Q)功率控制、在线数字P-Q测量以及中小企业系统的保护。所提出的GTO电路拓扑能够很好地提供独立的有功和无功控制，并保持中小企业系统的高效率和快速响应特性。
