Abstract

The invention discloses a lightning stroke detection system capable of lowering a lightning stroke trip-out rate for power transmission line reconstruction. The lightning stroke detection system comprises a lightning stroke detection terminal and a mobile data processing terminal, wherein the lightning stroke detection terminal comprises a solar power panel, a wind power generator, a storage battery, a wind-solar complementary controller, an inverter, a lightning stroke current sensor, an AD converter, a control module used for counting lightning stroke times according to lightning stroke current signals, and a first communication module used for receiving request instructions sent by the mobile data processing terminal and sending lightning stroke time data to the mobile data processing terminal in a wireless mode under the control of the control module. The first communication module establishes wireless communication connection with the mobile data processing terminal entering into a communication scope of the first communication module. The lightning stroke detection system supplements electric energy to the storage battery based on natural environment conditions by utilizing wind energy and solar energy, and effectively ensures the power supply operation of the system.

Description

technical field [0001] The invention relates to the field of power grid monitoring, and more specifically relates to a lightning strike detection system for transmission line reconstruction for reducing the lightning strike trip rate. Background technique [0002] According to the analysis of the generation and operation of the State Grid in recent years, among the 110-500kV equipment accidents, the number of lightning trips accounted for the first in the total number of trips of transmission equipment, and the proportion of unplanned outages of transmission equipment accounted for the second, which seriously affected the power grid. safe and reliable operation. [0003] When the power operation management department encounters a lightning strike fault on the transmission line, how to quickly monitor the location of the fault point is the key to organizing rapid repairs and restoring normal operation. Therefore, it is very necessary to provide a lightning strike indication m...
