摘要
Abstract
Due to the discrepancy of wave impedances between overhead lines and submarine cables,traveling wave fault location based on the dual side positioning principle can not adjust to the cable hybrid transmission lines.According to the needs of Hainan’s networking project,the distributed traveling wave fault location system is developed.Through installing monitoring terminals of traveling wave fault location at the junction of overhead lines and submarine cables,traveling wave direction,GPS time,and wave propagation velocity in different media can be recorded,and thus achieving fault interval mapping and precise positioning.The system is applied to 500 kV Fushan-Gangcheng line,known as Hainan’s networking project,whose operation verifies the system’s safty and reliability.关键词
