Monitoring system and monitoring method for transmission conductor galloping based on GPS

Abstract

The invention discloses a monitoring system and a monitoring method for transmission conductor galloping based on GPS (Global Position System). The monitoring system is characterized in that the monitoring system comprises a satellite signal receiving module, a satellite signal analyzing module, a digital signal processing module, a keyboard and a liquid crystal display module, a GSM (Global System for Mobile Communications) wireless communication module and a power supply management module. According to the monitoring system disclosed by the invention, two GPS antennae are fixed on an insulating string or suspended under a sample conductor; other parts of the monitoring system are respectively fixed on a tower head of a transmission conductor iron tower without influencing a galloping model of the conductor. The monitoring method disclosed by the invention has the advantages of favorable reliability, favorable dynamic performance, high technical level and capability of working all weather.

Description

[0001] This application is a divisional application with the filing date: October 15, 2010; the application number: 2010105085116; the title of the invention is: GPS-based transmission conductor galloping monitoring system and monitoring method. technical field [0002] The invention relates to a GPS-based power transmission conductor galloping monitoring system and monitoring method, especially after introducing a synchronous disturbance random approximation SPSA algorithm, which can better meet the real-time monitoring of power transmission conductor galloping. Background technique [0003] Galloping of transmission wires can cause huge economic losses and serious social impacts, and it is a worldwide problem! Since the 1930s, scholars at home and abroad have conducted a large number of experiments and theoretical studies on conductor galloping, and have achieved certain results. The current transmission conductor galloping monitoring system mainly adopts the following moni...

AI Technical Summary

Problems solved by technology

[0005] 1. Computer simulation technology monitoring is limited to theoretical research on the galloping of transmission wires and cannot be applied in engineering practice;

[0006] 2. The shortcomings of monitoring based on sensor technology are obvious. Only by arranging a large number of sensors on the transmission wire can more data be obtained, and the wire galloping curve can be fitted well, but the sensors themselves arranged on the transmission wire may damage The wire galloping model has become a safety hazard and poor operability;

[0007] 3. The image transmission rate of video image technology monitoring is low, the video signal is easily distorted, and the dynamic performance is poor; the camera is easily covered by snow, and it cannot work normally due to the influence of light at night, and it is impossible to monitor the transmission line around the clock
