Abstract

The invention relates to a large-capacity data processing method in extra-high voltage lightning invasion wave monitoring. The method comprises the following steps: displaying a lightning invasion wave waveform; counting a lightning invasion wave frequency; and displaying a lightning invasion wave interface. Aiming at the problems of large file data capacity and slow processing speed, the problems are solved by two methods; and the first method is that by a large file partitioning method, namely a file with a relatively large data quantity is equally divided into a plurality of files with relatively small data quantities, when the waveform is displayed, data of the entire file do not need to buffer, and only one part of appointed data need to buffer, so that, on one hand, the data can be quickly read and buffered, and meanwhile, the effect of quickly refreshing display is reached; and on the other hand, the problems of slow data updating and time delay in refreshing are effectively solved.

Description

technical field [0001] The invention relates to a large-capacity data analysis and display technology of lightning current intrusion waves, in particular to a method for processing large-capacity data in UHV lightning intrusion wave monitoring. Background technique [0002] At present, the research and application of lightning intrusion wave in the power industry is very extensive. Because the waveform of lightning intrusion wave is complex and difficult to predict, and the amount of data is large, it is difficult to analyze the characteristics of the waveform in a comprehensive and detailed manner. The research on the characteristics of lightning intrusion wave waveform will be It is of great significance to effectively prevent the damage caused by lightning intrusion waves in power grid substations. [0003] The general waveform graphic interface display method usually adopts the graphic cache method, opens up a memory area to store the processing data in advance, and refr...
