Embodiment Construction

[0026] In order to facilitate understanding of the present invention, it will be described below in conjunction with the accompanying drawings.

[0027] Please refer to figure 1 , a real-time lightning warning method for outdoor electrical equipment of the present invention, comprising the steps of:

[0028] 101. Obtain historical meteorological data;

[0029] Obtain historical meteorological parameters for several consecutive thunderstorms recorded. Collect n records recorded in history ST The eigenvalues ​​of the meteorological factors of the continuous location-dependent thunderstorm process with ≠0 include the average value of thunderstorm frequency f, current intensity I, charge Q, energy J, and rising steepness.

[0030] 102. Obtain real-time forecast weather data;

[0031] Get real-time forecast weather parameters for thunderstorms.

[0032] 103. Comparing historical meteorological data and forecast meteorological data to obtain the similarity coefficient;

[0033...

Abstract

The invention provides a real-time lightning stroke prewarning method for outdoor electric equipment, comprising the following steps of: acquiring recorded historical meteorological parameters of several continuous lighting storms; acquiring real-time forecast meteorological parameters of the lighting storms; comparing the historical meteorological parameters with the real-time forecast meteorological parameters to obtain a similarity coefficient of corresponding meteorological parameters; calculating a similarity value according to the similarity coefficient; and giving a lighting stroke alarm when the similarity value is larger than or equal to a preset threshold value. The invention also provides a real-time lightning stroke prewarning device capable of forecasting whether electric equipment is stroked by lighting or not in real time and giving an alarm.

Description

technical field [0001] The invention relates to the field of meteorological early warning, in particular to a real-time lightning early warning method and device for outdoor electrical equipment. Background technique [0002] The operation experience of the power system shows that the safety and reliability of the power grid are closely related to geographical and meteorological factors. Harsh geographical environment and extreme weather are one of the main reasons for the failure of long-distance transmission and distribution lines. The damage to power supply facilities caused by lightning strikes reaches a large amount every year. The damage, outage, arrester discharge, relay protection and reclosing action of the transmission line due to thunderstorm weather are called lightning strikes, which will seriously affect the transmission line, thereby affecting the safety and stability of the power system. The equipment damage, outage, lightning arrester discharge, relay prote...
