Power grid thunderstorm disaster early warning system and method based on identification and forecasting technology

Abstract

The invention relates to a system for power grid thunderstorm disaster warning based on recognition and forecast. The system is characterized by comprising a thunderstorm forecast information module, an early warning data analyzing module, a power grid thunderstorm risk early warning module and a display module all connected with one another in sequence. The invention further relates to a method which adopts the system to perform power grid thunderstorm disaster early warning. The system and the method utilize region thunderstorm characteristic and regional power grid characteristic, and combine the anti-thunderstorm design parameters and the on-site geographical conditions of power grid equipment including various transformer substations, electric transmission lines, pole and the like, so as to realize real-time automatic monitoring on the thunderstorm disaster, perform actual condition analysis quantitatively at a specific time and location and near-disaster early warning and perform fine instructional functions on production and scheduling of power grid.

Description

technical field [0001] The invention relates to a thunderstorm disaster early warning system, in particular to a power grid thunderstorm disaster early warning system based on identification and forecast technology. The invention also relates to a method for early warning of thunderstorm disaster in electric network by using the system. Background technique [0002] Meteorology is not only closely related to people's daily life, but also inseparable from the safety, stability, high-quality and economical operation of the power grid, as well as fine scheduling. Studying the relationship between the safe operation and scheduling of regional power grids and meteorological factors can provide a basis for power grid operation and scheduling. In particular, carefully analyzing and studying the relationship between electricity and thunderstorm weather is not only of great significance for arranging power grid operation plans in advance, improving power grid operation efficiency, s...

Problems solved by technology

It has the characteristics of strong suddenness, strong oncoming force, high intensity and short duration; it is highly harmful to the safe operation of the power grid. The heavy precipitation caused by thunderstorms will cause mass tripping of local lines and cause load loss. In severe cases It will lead to a complete stop of the plant and station, and the flood caused by the heavy rain will cause the transmission line to collapse, break the line and manifest as a permanent failure, damage the substation equipment, and even cause the full stop of the affected plant and station, seriously affecting the production safety of the power system

At present, although the meteorological data provided by the meteorological department to the society are relatively complete and the level of analysis is relatively comprehensive, they are all limited to the performance of meteorological content, and the meteorological information does not have the characteristics of real-time, continuity and reliability, and there is no connection The production and scheduling of the power sector lacks a comprehensive analysis of the relationship between meteorological information changes and power grid information changes, and cannot play a refined guiding role in the production and scheduling of the power grid
