Dynamic capacity increasing monitoring system and method for power transmission line

Abstract

The invention discloses a dynamic capacity increasing monitoring system and method for a power transmission line. The method comprises the steps of carrying out real-time monitoring on the power transmission line, acquiring monitoring data to calculate the safe operation current capacity of the power transmission line, judging whether capacity increasing can be carried out on the power transmission line according to the safe operation current capacity, and if yes, extracting preset capacity increasing information to carry out capacity increasing on the power transmission line; in the process of capacity increasing of the power transmission line, calculating the conductor sag data of the power transmission line according to the monitoring data, and sending the monitoring data and the conductor sag data to an application terminal to display the data. Data acquisition and data monitoring can be carried out on the power transmission line in real time, real-time monitoring is carried out on the conductor sag data of the power transmission line in the process of capacity increasing, the influence on safe operation of the power transmission line from various key factors is comprehensively considered, and therefore the safety is improved.

Description

technical field [0001] The invention relates to the technical field of electric power grids, in particular to a dynamic capacity-increasing monitoring system for transmission lines and a capacity-increasing monitoring method thereof. Background technique [0002] The dynamic capacity expansion system of transmission lines is an important part of the transmission link in the construction of the power grid, and an important technical means to improve the intelligent production and operation management of the power grid.

Problems solved by technology

Since only the temperature of the wire and the influence of the axial tension of the tensile section of the wire on the transmission line are considered in the process of capacity expansion, it is difficult to ensure the safe operation of the transmission line. The traditional monitoring system for dynamic capacity expansion of transmission lines has the disadvantage of low safety.
