Transmission line icing dancing monitoring and early warning device and method

Abstract

The invention discloses a transmission line icing dancing monitoring and early warning device and method. The device comprises a power supply control unit, an upper computer unit, a meteorological data processing unit, an icing model processing unit, a power grid information screening unit, a data integrated processing control unit and a remote early warning unit. According to the invention, a weather information acquisition module in the meteorological data processing unit acquires real-time weather data of the position of a transmission wire, and transmits the data to the icing model processing unit used for calculating an icing model; the icing model processing unit can send a calculation result to a dancing trip risk factor module to calculate the dancing probability when the wire surface is iced; transmission wire icing monitoring do not need a large number of sensors, so that the sensors are prevented from being damaged by bad field weather and other reasons; and wire surface icing monitoring and dancing monitoring are combined, so that an icing dancing monitoring result of the whole transmission line is accurate and reliable.

Description

technical field [0001] The invention relates to the field of power transmission line safety, in particular to a monitoring and early warning device and method for icing galloping of a transmission line. Background technique [0002] With the development of industrial productivity, long-distance transmission lines appear more and more frequently, so the safety of field transmission lines has become more and more important; the biggest threat to the safety of field lines is the surface of the wire. Conductor galloping is two major phenomena. However, there are problems in the traditional monitoring methods for these two phenomena of transmission lines. In risk prediction, the two phenomena of wire surface icing and wire galloping are generally monitored separately, which increases the monitoring device and also increases the difficulty of monitoring; on the other hand, when monitoring the phenomenon of wire surface icing, the traditional The best method is to install a large ...
