电力线路多点式故障定位方法研究

摘要

This paper presents multi type traveling wave fault location method based on traveling wave location method of tradition.The system uses multiple point fault detection method,provided with a plurality of moni-toring equipment in the power transmission line.The transmission time of the fault current traveling wave can be detected by monitoring device,so as to realize the accurate detection of the fault location in transmission line.The power supply device has been installed and running smoothly on the tower,practice proves the relia-bility and the effectiveness of the design.%在传统的行波定位法的基础上提出了多点式行波故障定位法，该系统采用多点式故障检测方法，在输电线路上安装若干个监测装置，由监测装置检测线路故障电流行波的传输时间，从而实现精确检测输电线路故障点的位置。该供电装置已经安装在杆塔上平稳运行，实践证明了该设计的可靠性及有效性。
