Abstract

The embodiment of the invention relates to a rocket thunder leading electric data acquisition device and method, and a thunder leading line length determination method. The rocket thunder leading electric data acquisition device comprises a thunder leading emission device and an acquisition device connected with the thunder leading emission device, and the acquisition device comprises a thunder parameter acquisition device and a thunder image acquisition device. According to the rocket thunder leading electric data acquisition device, continuous thunder strike is generated through the thunderleading launching device, the thunder current waveform and the thunder image of the continuous thunder strike are acquired through the thunder parameter acquisition device and the thunder image acquisition device, acquisition of continuous thunder strike parameters is achieved, and data are provided for analyzing the influence of thunder strike on an electric power system. The technical problem that the result of analyzing the harm of lightning stroke to the power system is inaccurate due to lack of continuous lightning stroke parameter acquisition in the prior art is solved. The method for determining the length of the thunder leading wire can guide selection of the thunder leading wire, considers both the thunder leading success rate and the similarity between rocket thunder leading andactual thunder, and improves the thunder leading success rate.

Description

technical field

[0001] The invention relates to the technical field of lightning information collection, in particular to a lightning data collection device and method for rocket-induced lightning and a method for determining the length of a lightning-induced wire. Background technique

[0002] Lightning strikes will not only cause fault tripping of overhead lines, but also cause damage to equipment in substations. In recent years, continuous lightning strikes have caused frequent damage to circuit breakers, current transformers and arresters, which has become one of the key factors that threaten the stable operation of power systems.

[0003] Most of the existing studies on lightning strikes focus on a single lightning strike. According to the lightning statistics measured by the lightning location system, lightning usually contains multiple return strikes, and the amplitude of the main discharge is not necessarily the highest. Since lightning in nature is usually difficul...
