A Calculation Model for On-Line Monitoring of Conductor Galloping Based on the Length Method

Abstract:

This paper analyzed the advantages and disadvantages of several current on-line monitoring approaches to transmission line galloping, noting the comparatively strong economy and feasibility in the Conductor Length Method. Based on the length method, taking the data measured at tension sensors and the angle sensors as the basic parameters, this paper established a calculation model for the monitoring of galloping. The paper applied this model into calculations, whose results basically consistent with the on-site monitoring data, which verifies the accuracy of the calculation model.
