高压电缆—架空线混合线路故障测距方案研究
Fault Location Scheme of Cable-Overhead Hybrid Transmission Lines
【摘要】 针对高压电缆—架空线混合线路特点,提出了一种新型测距方案。该方案先通过一种新型电抗继电器识别故障区段,然后基于双端测距方案计算故障位置,解决了混合线路常规测距方案因混合线路参数不均匀导致的测距误差较大的问题。
【Abstract】 According to the characteristics of the hybrid transmission lines consisting of power cables and overhead lines,a new fault location scheme is proposed.The scheme firstly identifies the fault section by a new reactance relay,then calculates the fault location based on double terminal fault location method,therefore,conducive to solving the problem of the large hybrid-line measurement errors due to uneven parameters by using conventional fault location scheme.
