摘　　要：当线路检修或设备故障时,合环是解决不断电倒负荷的重要手段。目前对于合环的操作,调度都是基于经验法进行操控,往往因为合环两侧的电压差,相位差等造成馈线中出现较大的合环电流,影响负荷的正常工作,严重的甚至引起停电故障。为解决合环线路中的环流问题,提出一种基于超导储能装置(Superconducting Magnetic Energy Storage,SMES)的电磁合环环流抑制方案,并在PSCAD中搭建了仿真模型,分别验证了SMES在合环两侧负荷不同和变压器参数设置不同情况下,SMES对合环后馈线中电磁环流的抑制效果,最后仿真验证了所提方案的可实施性。The closed-loop is an important means to solve the problem of continuous power down load when the line maintenance or equipment failure occurs.The loop closing operation scheduling is manipulated based on experience method,because of the voltage difference on both sides of the loop,the phase difference caused by closed loop current is larger on the feeder,which will affect the normal working load,and even cause outages.In order to solve the circulation problem in the closed-loop circuit,the circulation suppression scheme of electromagnetic based on SMES(superconducting magnetic energy storage)closed-loop is proposed,and the simulation model is built in PSCAD,which was verified by SMES in ring on both sides of different loads and transformer parameters under different conditions,the inhibitory effect of SMES on electromagnetic circulation loop after the last line,and the simulation shows that the proposed scheme can be implemented.
