Abstract
The invention discloses a lightning stroke discharge comprehensive analysis method, device and terminal equipment and a storage medium. The method comprises a step of acquiring the relative time relation of an optical image, an optical radiation signal, an electric field signal, a magnetic field signal, a thunder signal and a photographing start signal in a lightning stroke discharge process froma fixed-point near-area observation system and lightning electromagnetic wave characteristic parameters from a wide-area lightning monitoring system, a step of analyzing a lead development characteristic, a relative integral brightness and an M component characteristic of the lightning stroke discharge to obtain an optical signal characteristic according to the relative time relation of the optical radiation signal, the optical image and the photographing start signal, a step of analyzing array parameters of a thunder sound source positioning device, thunder identification and thunder sound source positioning according to the thunder signal to obtain acoustic signal characteristics, and a step of analyzing the lightning electromagnetic wave characteristic parameters to obtain lightning discharge engineering parameters. The change rules of electricity, magnet, light, sound and other physical parameters in the lightning discharge process can be mastered, and the calculation accuracy of the lightning overvoltage of the power grid can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of lightning observation, in particular to a lightning discharge comprehensive analysis method, device, terminal equipment and storage medium. Background technique [0002] Lightning is an instantaneous discharge phenomenon that occurs frequently in nature. The discharge process is accompanied by effects such as strong electric field, strong magnetic field, high current, strong bright light, strong shock wave and strong electromagnetic radiation, which can cause serious damage to power facilities distributed in a wide area. damage, long-term threat to the safe and stable operation of the power grid. In recent years, with the rapid increase in the number of microelectronic devices in power plants, substations, power dispatching and communication buildings, etc., the electromagnetic damage caused by lightning has become more serious. At present, my country's power system has adopted a variety of lightning pro...
