摘　　要：本文从消弧线圈不同档位下小扰动接地试验角度出发,建立了校验自动跟踪补偿消弧线圈装置性能的技术体系,提出分别在消弧线圈aa、bb、cc三个挡位下,进行小扰动单相高阻接地试验,其中aa档为自动跟踪补偿消弧线圈给出的控制挡位,bb档为aa档基础上降低2档,cc档为aa档基础上增加1档,若bb、cc挡位下的两次接地试验中,接地残流与非接地相线电压计算的有功功率值,符号相反且aa、cc挡位下的两次接地试验中,接地残流与非接地相线电压计算的有功功率值,符号相同,则自动跟踪补偿消弧线圈装置性能补偿性能优越,反之,性能较差。仿真试验的结果验证了本文所提方法的正确性。A technical system for verifying the automatic tracking compensation performance of arc suppression coil device is established in this paper,from the perspective of the small disturbance based grounding test under different taps of arc suppression coil.It is proposed that the small disturbance based single-phase high resistance grounding tests should be carried out in three taps of arc suppression coils:aa,bb,and cc.Among them,the tap aa is the control tap given by the arc suppression coil with automatic tracking compensation,the tap bb is 2 taps below the tap aa,and the tap cc is 1 tap above the tap aa.If the active power values calculated by the ground residual current and the non-grounded phase line voltage have opposite signs in the two grounding tests under the tap bb and the tap cc,and the active power values calculated by the ground residual current and the non-grounded phase line voltage have the same signs in the two grounding tests under the tap aa and tap cc,the arc suppression coil device with automatic tracking compensation has superior compensation performance.On the contrary,the performance is poor.The result of simulation tests verified the correctness of the method proposed in this paper.
