Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The dynamic monitoring and capacity expansion of the transmission line is to install an online monitoring system on the transmission line to monitor the temperature of the transmission line and the meteorological conditions (environmental temperature, sunshine, wind speed, etc.) around the transmission line in real time, without breaking the current technical regulations. , Send the field sampling data to the monitoring center, and calculate the maximum allowable carrying capacity of the wire according to the mathematical model, make full use of the hidden capacity of the transmission line, and increase the transmission capacity of the transmission line.

[0031] The structure of the online monitoring system of the present invention, as figure 1 As shown, including the provincial bureau monitoring center 1, the provincial bureau monito...

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 line under 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 expansion 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 line transmission capacity, and the electric energy transmitted cannot meet the actual needs of the power grid. Therefore, new transmission lines and line corridors are constructed The investment is huge and the construction period is long. At present, static temperature increase and capacity increase technology and dynamic monitoring and capacity increase technology are used to increase the transmission capacity of existing transmission lines. However, the static temperature increase and capacity increase technolog...
