| 摘 要： | 失超保护是保证磁体安全运行的重要措施,而失超检测是失超保护正常动作的前提。由于SMES磁体运行工况的特殊性,现有失超检测方法在失超信号提取上遇到电磁噪声干扰严重的问题。文中针对高温超导SMES的运行工况,对电桥检测法进行了改进,通过对电桥信号的滤波设计解决电磁噪声干扰,设计了一套适用于高温超导SMES磁体在交变电流情况下的失超检测系统,同时进行了高温超导磁体的失超检测实验。实验结果表明,此系统能快速、准确地检测失超信号,并输出保护动作信号。

| Abstract: | The quench detection of SMES magnet is a key problem for the practical application of SMES in the electrical power system.A serious problem of quench detection methods is electromagnetic noise interference.This paper reduced the signal noise of bridge detection method by filtering the bridge signal,and designed a quench detection system can be used for the SMES magnet in the case of the alternating current.The quench detection experimental results indicate that the quench detection system can quickly and accurately detect the quench signal and carry out the protection action signal. |
