System for online monitoring icing and deicing processes of power transmission line

Abstract

A system for online monitoring icing and deicing processes of a power transmission line comprises a plurality of wireless temperature sensor nodes, a plurality of party lines, a GSM communication module and a monitoring center, wherein, the wireless temperature sensor nodes acquire and send the temperature information of monitoring points on the power transmission line; the party lines monitor the power transmission line and the changes of ambient environment parameters, receive the information transmitted by the wireless temperature sensor nodes, perform pre-treatment and storage to two paths of information, and send the treated information to the GSM communication module; the GSM communication module is used for transmitting the received information to the monitoring center, and transmitting the received orders to the party lines; and the monitoring center is used for sending orders, performing analysis, treatment and storage to the received information, carrying out remote management and remote setup to the monitoring party lines, and providing deicing parameter information, historical data querying and alarming record querying. The monitoring system of the invention can perform online monitoring to the icing and the deicing processes of the power transmission line in real time.

Description

technical field [0001] The invention belongs to the technical field of monitoring equipment for the status of power transmission and transformation equipment, and relates to an on-line monitoring system for power transmission lines, in particular to an on-line monitoring system for the icing and melting process of power transmission lines. Background technique [0002] Affected by the macro-climate, micro-topography, and micro-meteorological conditions in my country, ice disaster accidents occur frequently, seriously affecting the safe operation of the power grid. Icing of large-scale transmission lines can cause serious damage to the power grid, resulting in paralysis of the power grid. In order to ensure the safe operation of the power grid, it is necessary to monitor the icing situation of the transmission line, and take corresponding ice-melting measures according to the monitored icing information to improve the reliability of the transmission line operation in the icin...

AI Technical Summary

Problems solved by technology

Since the icing of the transmission line is affected by the microclimate, topography, landform and many random factors of the environment where the transmission line is located, the mathematical model is difficult to determine, resulting in the inaccurate monitoring of the existing icing monitoring system, and the monitoring system only It can give early warning information of icing, but cannot monitor the icing process of transmission line icing in real time after the icing measures are started.
