Method and system for monitoring and early warning of ice and snow coverage on transmission line

Abstract

The invention provides a method and system for monitoring and early warning of ice and snow coverage on a transmission line. According to the method, a line pressure, a first tension, a first deformation quantity, a second tension, a second deformation quantity, an ambient temperature and a wind speed of a transmission line are obtained and the obtained information is sent to a management server;the management server carries out processing and analysis based on the obtained information, determines an ice and snow coverage or icing situation, generates early warning information of different levels, and sends the early warning information to a regional server; and the regional server sends the early warning information to a user terminal. Since the line pressure, the first tension, the first deformation quantity, the second tension, the second deformation quantity, the ambient temperature and the wind speed of the transmission line are obtained in real time, the ice and snow coverage oricing situation of the transmission line is determined in real time effectively; all-weather and cross-terrain monitoring is realized; no manual line inspection is needed; early warning is sent out timely; and fault occurrence at the transmission line due to the rain or snow is prevented effectively.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of power transmission lines, in particular, to a method and system for monitoring and early warning of ice and snow covering power transmission lines. Background technique [0002] In rainy and snowy weather, the tension of the transmission line increases. When encountering heavy snowy weather, the transmission lines erected in the wild are easily covered with snow or ice, which will further increase the tension of the line. If the overburdened snow is not removed in time If the snow is frozen and then snow is accumulated, it is easy to cause the line to be broken and cause a large-scale power outage. Therefore, it is necessary to monitor the snow or ice coverage of the transmission line in real time. At present, most of them are monitored by manual inspection. For complex terrain It is impossible to realize all-weather monitoring, so a device or system that can monitor the ice-snow or ...
