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...
