Online monitoring system of dynamic compatibilization of power transmission line

Abstract

The invention relates to an online monitoring system of dynamic compatibilization of a power transmission line, comprising a provincial bureau monitoring center which is respectively connected with a plurality of city bureau monitoring centers by an LAN bus; each city bureau monitoring center is respectively connected with a plurality of monitoring main stations by a GSM SMS; and each monitoring main station is respectively connected with a plurality of monitoring substations by radio. The online monitoring system carries out timing / real-time acquisition to the information of the temperature of the power transmission line and the temperature, humidity, wind speed, wind direction and irradiance and the like of the surrounding environment of the power transmission line, calculates the allowable current-carrying capacity of the power transmission line, analyzes objective recessive capacity of the power transmission lines, and improves the conveying capacity of the power transmission lineunder the condition that the current technical regulation and stipulation is not broken.

Description

Technical field [0001] The invention belongs to the technical field of power transmission and transformation equipment monitoring, and relates to an online monitoring system for dynamic capacity increase of power transmission lines. Background technique [0002] In recent years, with the continuous and rapid growth of the social economy and the rapid growth of electricity load, the existing transmission lines are restricted by the thermal stability limit of the transmission capacity of the line, and the transmitted electric energy cannot meet the actual needs of the power grid. Therefore, new transmission lines and line corridors are built. The investment is huge and the construction period is long. At present, static temperature increasing and capacity increasing technology and dynamic monitoring and capacity increasing technology are used to increase the transmission capacity of existing transmission lines. However, the static temperature increase and capacity increase technol...
