摘　　要：超导磁储能(Superconducting Magnetic Energy Storage,SMES)技术所具有的高效性、响应快、无限循环等特征与可再生能源下的微电网结合有重要价值,应设计优秀的算法用以控制变流器,并调整微电网运行中所存在的波动性与不稳定性。由此,提出FABP-PID下的微网超导储能电流型变流器的控制方法,该方法融合复合载波PID控制,模糊控制与ABP神经网络的控制思想,并充分考虑了被控对象的拓扑构造和工作模式,以及三相五电平CSI的电流特征。通过35 kJ/7 kW超导磁储能微电网实验系统所获得实验结果表明,所产生的交直流纹波小,波形不易发生畸变且调整速率较快;当发生扰动时,所控制的SMES型微电网系统稳定性较好。The characteristics of superconducting magnetic energy storage(SMES)technology,such as high efficiency,fast response and infinite cycle,are of great value in combination with microgrids in renewable energy.However,excellent algorithms should be designed to control the converters and adjust the fluctuation and instability in the operation of microgrid.Based on this,a three-phase five-level CSI control method based on FABP-PID method was proposed.On the basis of compound carrier PID control,the control idea of fuzzy control and ABP neural network was combined,and the topology structure and working mode of the controlled object as well as the current characteristics of three-phase five-level CSI were fully considered.The experimental results obtained by 35 kJ/7 kW superconducting magnetic energy storage microgrid experimental system show that the proposed method generates small AC/DC ripple,waveform distortion is not easy to occur and the adjustment rate is fast.In addition,the SMES microgrid system controlled by our method has better stability when disturbance occurs.
