摘要
电压型超导储能(Superconduction Magnetic Energy Storge,简称SMES)系统的斩波器用于对超导磁体快速稳定充放电。研究了SMES系统用斩波器充放电的工作原理,采用状态空间平均法建立其数学模型,并提出一种斩波器充电、放电的闭环控制方法。基于第2代高温超导磁体及其限流保护,搭建了斩波器实验系统,应用DSP2812处理器实现对超导磁体充放电的控制。实验结果表明,所应用斩波器控制方法的性能良好,可以满足SMES系统的要求。
The chopper of voltage source converter SMES is used to charge and discharge the superconducting mag-net.Charging and discharging working principles of SMES chopper are studied.The state-space averaging method is used to establish the mathematical model of chopper and loop feedback control is proposed for the chopper charging and discharging.Considering the actual inductance of magnet coil and its current-limiting protection,a SMES chopper experimental system is set up by using DSP2812 control system.The results show the validity of the proposed control method and prove that the SMES chopper can meet the requirements of high temperature superconducting magnetic energy storage（HT-SMES）.
