Research of Windage Fault Early Warning Technology for Overhead Transmission Lines Based on Multi Parameters

Windage trip is the most common type of wind damage in transmission lines, which is mainly caused by the lack of electrical clearance distance after the guide line deflects under the action of wind. It occurs under the working voltage, and its success rate of reclosing is low, which seriously affects the reliability of power supply. The automatic diagnosis model of wind deflection fault of overhead transmission line and the windage early warning strategy are studied and completed based on multi-channel monitoring data, Which can realize multi-channel monitoring data fusion of on-line monitoring device, respond to windage fault quickly, find out channel environment and transmission equipment abnormalities in time, and provides important basis and auxiliary decisionmaking for windage control of overhead transmission lines.
