摘　　要：在消弧线圈接地系统电网模型理论分析的基础上,根据电网实际运行状况,对传统的位移电压的调谐算法进行改进,同时分析了线电压与自然不平衡电压的关系。在电网中单相接过渡电阻以改变其自然不平衡度,最终通过在"MNDW—Ⅱ型小电流接地电网动态模拟系统"平台上的相关实验,对比了两种调谐算法,证明了改进算法的可行性。Based on the analysis of the model for arc-suppression system, and referred to the actual work situation of the power network, a method is put forward to improve traditional automatically tuning principle, and the theoretical relationship between phase-to-phase voltage and natural unbalance voltage is analyzed. Finally, a transition resistance on one phase wire is set, then a series of trials at the “ MNDW-Ⅱ simuiate system of small current” are carried out. By comparing these two tuning principle through the whole experiment, it is demonstrated that this automatically tuning principle is feasible.
