摘　　要：为研究超导储能 (SMES)装置提高电力系统暂态稳定性的作用 ,从超导储能系统的运行机理出发 ,建立了超导储能的单桥系统和双桥系统数学模型 ,并实现了有功控制和有功无功综合控制的各种控制策略。在单机无穷大和多机系统上的计算机仿真表明 ,超导储能装置能有效地提高电力系统的暂态稳定性。论文研究了控制方式对暂态稳定性的影响 ,对影响其效果的多种因素 ,如安装地点等 ,也进行了比较详细的研究。The objective of this paper is to investigate the application of a Superconducting magnetic energy storage (SMES) system for enhancing transient stability. The SMES principles are used to develop models of both the SMES single bridge system and the double bridge system. Control strategies have been designed for active power control and a comprehensive control strategy for simultaneous modulation of active and reactive power. Computer simulations on both a single machine infinite system and a multimachine system show that SMES significantly improves the transient stability. The effect of active power control is compared to simultaneous active and reactive power control, the effect of the location of the SMES in the power system is also studied.
