Problems solved by technology

The galloping of the transmission wire is a kind of self-excited vibration with low frequency (about 0.1-3Hz) and large amplitude (about 5-300 times the diameter of the transmission line). The galloping of the wire is very harmful and can easily cause phase-to-phase flashover, Damaged fittings will cause line tripping and power outages or cause serious accidents such as transmission line burns, transmission line breaks, tower collapses, etc., resulting in major economic losses and adverse social impacts. It is a major safety hazard affecting the operation of transmission lines

Abstract

The invention provides a power transmission line galloping monitoring system and method, relates to the technical field of cable galloping monitoring, and can provide power transmission line gallopingearly warning for users. The power transmission line galloping monitoring system comprises a galloping data acquisition unit, a server and an alarm unit, and is characterized in that the galloping data acquisition unit acquires galloping data of a power transmission line in real time and transmits the galloping data to the server; the server receives and processes the galloping data in real time,receives the meteorological parameters and the power parameters in real time, predicts the galloping trend of the power transmission line in a future period of time according to the galloping data, the meteorological parameters and the power parameters, and sends an alarm signal to the alarm unit; and the alarm unit receives the alarm signal in real time and gives an alarm correspondingly. The power transmission line galloping trend in a period of time in the future is predicted by utilizing the galloping data, the meteorological parameters and the power parameters, and power transmission line galloping early warning is provided for users on the basis of monitoring the galloping condition of the power transmission line in real time.

Description

technical field [0001] The present disclosure relates to the field of cable galloping monitoring, and in particular to a system and method for galloping monitoring of power transmission lines. Background technique [0002] The low-frequency, large-scale self-excited vibration phenomenon of overhead conductors with uneven ice coating along the circumferential direction under the action of lateral wind is called galloping of transmission conductors. The galloping of the transmission wire is a kind of self-excited vibration with low frequency (about 0.1-3Hz) and large amplitude (about 5-300 times the diameter of the transmission line). Damaged fittings can cause line tripping and blackouts or serious accidents such as transmission line burns, transmission line breaks, tower collapses, etc., resulting in major economic losses and adverse social impacts. It is a major safety hazard affecting the operation of transmission lines. [0003] The galloping problem of transmission line...
