Power transmission line mountain fire tripping test platform data full-automatic collecting and controlling method

Abstract

The invention discloses a power transmission line mountain fire tripping test platform data full-automatic collecting and controlling method. A voltage adjuster power supply is started, and a voltage adjuster adjusts power transmission line voltage to a power transmission line voltage level to be simulated; measured values of voltage at the high-voltage sides of a transformer and a leakage current collecting device are transmitted to a conditioning circuit and are converted into digital signals which are then transmitted to a data collecting card; current and voltage data collected by the data collecting card are transmitted to a computer through a PCI bus, through analysis of power transmission line mountain fire tripping test soft developed based on LabView software installed in a computer, the leakage current and the power transmission lien voltage data of a power transmission line mountain fire tripping test platform are obtained; and after burning is stable, a power transmission line discharging process is observed and simulated. Data such as temperature, fuel weight, smoke concentration, flame conductivity, electron ion concentration in flame, wind speed, wind direction and current and voltage of a transmission line during power transmission line mountain fire tripping testing can be collected automatically, accurately and completely.

Description

technical field [0001] The invention relates to the technical field of transmission line mountain fire prevention and control, in particular to a data automatic collection and control method of a transmission line mountain fire trip test platform. Background technique [0002] In recent years, due to the continuous drought and the impact of the production and life of residents near the transmission line, wildfire accidents in the transmission line corridor have occurred frequently, seriously threatening the safe and stable operation of the power grid. In terms of research on the mechanism of transmission line tripping caused by wildfires, many researchers at home and abroad have made a lot of explorations by establishing a simulation laboratory for transmission line wildfire tripping. At present, there is no automatic data collection and monitoring system for the transmission line mountain fire tripping platform. During the test, the data at a certain time point is mostly ma...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the complex tripping mechanism of transmission lines under wildfire conditions, there are a lot of data that need to be recorded. The way of manual data recording has the problem of reading errors, which greatly increases the workload of experimenters and reduces the efficiency of experiments;

[0005] 2. The influencing factors of mountain fire tripping of transmission lines are also changing with the combustion process. Therefore, it is difficult to ensure the accuracy and completeness of the data of mountain fire tripping of transmission lines by the fixed time point recording method, so as to obtain inaccurate mountain fire tripping data of transmission lines. The law of fire tripping and influencing factors is not enough to guide the actual grid fire prevention;

[0006] 3. During the mountain fire tripping experiment of the transmission line, the temperature near the combustion platform is high due to radiant heat, and the transmission line may break down the air gap under the condition of the mountain fire. pose a threat to personal safety

[0007] In addition, since many measuring devices cannot perform measurements under the condition of simulating the transmission line with high voltage, otherwise it will cause the transmission line to discharge the measuring device

Therefore, the existing transmission line mountain fire tripping test does not collect data such as ionization degree and smoke concentration, and cannot quantitatively analyze the impact of these factors on transmission line mountain fire tripping
