T接线路暂态保护分析

Analysis of Transient Protection in Teed Circuit

基于故障暂态电流的单端量无通信保护用于T接线路,根据故障暂态电流的特点,利用Daubechies小波计算暂态保护判据。通过在不同的故障位置、不同的过渡电阻、不同的故障时间以及各种故障类型的情况下,对实际T接线路进行的详细仿真,证明了暂态保护应用于T接线路的可行性。

The non-communication protection based on fault generated transient current component is used in teed circuit and that in terms of the feature of fault generated transient current component, transient protection criterion is computed by use of Daubechies wavelet. The detailed simulation which is carried out in the different positions, in the different transition resistances, in the different fault generating times and the different fault types tests the feasibility that the transient protection is suitable for use in teed circuit.
