摘　　要：文章通过实际计算和理论分析,证明了在东明开关站启动调试过程中出现的过电压现象是由系统参数设置不当而发生串联电压谐振引起的。就定义谐振电压比这一概念,讨论了同杆并架线路中串联电压谐振的发生条件,以及谐振电压比在谐振点附近的频率变化特性。With theoretical analysis and practical calculation it is proved that the overvoltage phenomenon which appeared in the startup and adjustment process of Dongming switching station is a serial voltage resonance caused by the parameter mismatch. By defining the scale of resonance voltage (SRV) the occurrence condition of serial voltage resonance in the line of double circuits on same tower and the frequency characteristics of SRV at the position near the resonance point are discussed.
