摘　　要：采用分布参数模型,精确计算分析了同杆双回线单线高阻接地的特征.研究表明,同杆双回线的单线高阻接地保护可用于在高阻接地故障的初始阶段,在常规线路保护动作之前切除故障.By precise model of distributed parameters, the single line grounding fault of double lines on the same tower through high resistance is accurately calculated and precisely analyzed. Based on the grouding fault characters of double lines through high resistance, the protection method proposed could cut off grounding fault before line relays take action.
