The invention discloses a data analysis and optimization method for lightning-to-ground lightning on a transmission line, relates to a lightning detection and optimization method, and solves the problem that the lightning data processing capability and analysis speed cannot meet the needs of operation and maintenance. The present invention includes constructing an optimization model, selecting a regional transmission line group that matches the region to be analyzed in the historical data as the training set data, and setting the hyperparameters loaded in the LSTM model to select the attribute data of the transmission line in the region to be analyzed, and the LSTM model to output data Corresponding to the verification set data corresponding to the training set data in the historical data, an evaluation module is set up, and the evaluation module evaluates and calculates the difference to obtain a balance between precision and recall rate, and recursively calculates to obtain that the regional influence status to be analyzed is within the acceptable range of the region The intensity and range of lightning flashes. In the recursive calculation process of the invention, the number of data groups in the training set is reduced, the calculation efficiency is improved, and at the same time, the situation of lightning and ground flash can be accurately judged.
Description
Technical field [0001] The present invention relates to a lightning detection optimization method, specifically to a transmission line lightning ground flash data analysis optimization method. Background [0002] With the rapid development of the scale and voltage level of the power grid, the improvement of the national economic level, and the mushrooming of various intelligent and weak current equipment, lightning has caused huge economic losses and human and animal injuries to the whole country. [0003] Lightning is accompanied by a strong convection process and a kind of catastrophic weather phenomenon, because of its strong current, violent shock wave and strong electromagnetic radiation and other physical effects, can produce a huge destructive effect in an instant, damage the power supply and distribution system and communication equipment, resulting in power supply paralysis, computer information system, telephone communication system interruption, endangering people's pr...
