Abstract

The invention provides an extra high voltage transmission line online monitoring system, comprising that a data collection terminal collects comprehensive load, temperature of a transmission line, inclination angle of a pole, inclination angle of an insulator string, leakage current of the insulator string, meteorological information, vibration of transmission line and vibration of the pole, transmits the collected signals to a central data processing unit; the central data processing unit performs anti-interference process on each signals, packs and transmits to a background analysis device through a wireless communication network, and displays data information on a GIS electronic map; the background analysis device determines whether the transmission line is abnormal or not based on each signal and combination of mathematical model, transmits alarm information in time when being abnormal. The invention performs anti-interference process on the collected data, is capable of shielding interference of extra high voltage strong electromagnetic field and accurately monitoring working conditions of extra high voltage transmission line.

Description

technical field [0001] The invention relates to the technical field of UHV transmission equipment, in particular to an on-line monitoring system for UHV transmission lines. Background technique [0002] Since nearly 2 / 3 of my country's exploitable hydropower resources are in the west, and 2 / 3 of coal resources are in Shanxi, Shaanxi and Inner Mongolia; however, 2 / 3 of my country's electricity load is distributed in the eastern coastal areas and economic areas east of the Beijing-Guangzhou Railway. developed areas. In this way, it is necessary to transmit the power generated by the energy base to the central and eastern regions where the power demand is large. [0003] In order to reduce transmission loss and improve transmission quality, my country is currently developing UHV transmission technology. UHV AC transmission refers to AC transmission projects and related technologies with a voltage level of 1000kV and above. UHV transmission technology has the characteristics o...
