Abstract


This paper, taken the railway 10kV automatic blocking electric line as the research object, discusses some structure factors which may affect the ranging accuracy of traveling wave method in the practical application of traveling wave fault location device, and establishes the simulation model to verify. These structure factors include the effect of transition resistance, terminal load combination form and the line branches' number before fault point.

Keywords


Automatic blocking power line, Single-end/ double-end traveling wave fault location, Ransition resistance, Terminal load combination form, Line branches’ number before fault point
