Power transmission line galloping monitoring system

Abstract

The invention relates to a power transmission line galloping monitoring system. The system comprises a first data acquisition module which is installed on a power transmission line and is used for acquiring first monitoring data at a first set time interval; a second data acquisition module, arranged on a tower and used for acquiring second monitoring data at a second set time interval; a controller, respectively connected with the first data acquisition module and the second data acquisition module, and used for outputting a control instruction through the communication module to control thefirst data acquisition module and the second data acquisition module to increase the acquisition frequency to obtain secondary monitoring data when the galloping acceleration, the icing thickness andthe tension data or meteorological data of the power transmission line exceed set thresholds; judging whether the power transmission line gallops or not according to the secondary monitoring data. Thereal-time performance and accuracy of galloping monitoring are improved, and the monitoring strength of power operation and maintenance personnel on the galloping disaster of the power transmission line is improved.

Description

technical field [0001] The invention relates to the field of power transmission line state monitoring, in particular to a power transmission line galloping monitoring system. Background technique [0002] With the increasing scale of the power network, transmission lines are the main means of power transmission, and their safe and stable operation is the primary issue that must be considered in our country. Among them, conductor galloping is a serious disaster that endangers the safe and stable operation of the line. It is a low-frequency, large-amplitude self-excited vibration generated by eccentric ice-coated conductors under the excitation of wind, which often causes flashover tripping, hardware and insulators Damage, broken strands and broken wires of wires, loosening and falling off of tower bolts, damage to tower materials, damage to foundation, and even serious accidents such as tower collapse. [0003] Existing dancing monitoring is mainly divided into two parts: ha...

Problems solved by technology

In practical applications, this method will encounter the problems of sensor layout and wire twisting, which will lead to monitoring deviations of each sensor, and packet loss is easy to occur due to network waveforms during transmission, resulting in large errors in analysis results and frequent false alarms. many

Moreover, the transmission of a large number of sensors has high requirements on bandwidth, and there are many redundant data, resulting in waste of resources
