摘要/Abstract

摘要： 高温超导磁储能系统（SMES）是一种功率型的储能装置,本文介绍了国内自主研发的150 kJ/100 kW直接冷却高温超导磁储能系统的总体结构和基本试验结果。高温超导磁体由Bi2223/Ag和YBCO两种超导带材绕制而成,通过直接冷却方式将储能磁体成功冷却到了17 K左右。经测试,储能磁体的直流临界电流达到180 A,临界储能量157 kJ,磁体中心场强4.7 T;该SMES能快速独立地在四象限进行有功功率和无功功率交换,响应速度小于10 ms;在电力系统动态模拟实验中,SMES有效抑制了电力系统中因发电机机端短路故障引起的功率振荡。

Abstract: This paper describes a 150kJ/100kW directly cooled high temperature superconducting electromagnetic energy storage (SEMS) system recently designed, built and tested in China. The high temperature superconducting magnet is made from Bi2223/Ag and YBCO tapes, which can be brought to ~17K through direct cooling. Preliminary experiments have shown that the critical current of the superconducting magnet reaches 180A with a maximum energy storage capacity of 157kJ and a maximum central magnetic field of 4.7 T. The 150 kJ/100 kW SMES has been found to respond very rapidly to active and reactive power independently in four quadrants of an AC power system, with a response time of less than 10 ms. It is also shown that, in a dynamic simulated experiment, the SMES can effectively damp power oscillation due to line fault of line to ground at the generator terminal.

Key words: superconducting magnet energy storage (SMES), superconducting magnet, directly cooled, stability of power system
