摘　　要：提出了基于暂态行波的过渡电阻估算方法,利用故障初始行波与故障点反射波幅值/对端母线反射波比值计算过渡电阻,通过PSCAD电磁暂态仿真验证了方法的有效性。In this paper, a transient traveling wave based transition resistance estimation method is proposed. The transition resistance is calculated by using the initial traveling wave of the fault and the reflected wave amplitude value of the fault point/the reflected wave ratio value of the opposite end bus. The effectiveness of the method is verified by PSCAD electromagnetic transient simulation.
