应用于超导储能的功率调节系统

Design and Experiments of Power Conditioning System for SMES

讨论了一种适用于超导储能(Superconducting Magnetic Energy Storage,简称SMES)的电流型功率调节系统。主电路设计采用了模块化结构,易于扩容;控制电路采用以主控DSP和MCU为核心的两级结构。利用瞬时功率检测方法所得到的有功功率和无功功率进行功率闭环控制。实验结果说明,功率调节系统能够在四象限内快速、独立地控制有功功率和无功功率。单机无穷大系统的三相短路实验表明,超导储能系统能够显著抑制发电机的功率振荡。

A multi-module current source power conditioning system （PCS） for superconducting magnetic energy storage （SMES） is developed.A master DSP and slave MCU structure is selected to implement power control.An active and reactive power control strategy under instantaneous power detection is designed for this PCS.Experimental results are shown that it can control active power and reactive power independently and rapidly.The effectiveness of SMES to damp the low frequency oscillation of generator is verified.
