Power grid typhoon and flood disaster early warning method and device

Abstract

The invention provides a power grid typhoon and flood disaster early warning method and device. Rainfall prediction information is acquired based on a mesoscale numerical prediction mode; the rainfallforecast information is input into a pre-constructed power grid typhoon and flood disaster early warning model to obtain power grid typhoon and flood disaster early warning information; the power grid typhoon and flood disaster early warning model is determined through a pre-designed typhoon and flood disaster forecasting grid and characteristic parameters of the typhoon and flood disaster forecasting grid, the obtained power grid typhoon and flood disaster early warning information is high in reliability, it is guaranteed that the power grid typhoon and flood disaster emergency response capacity is high, the material allocation efficiency is high, and losses are reduced; the power grid typhoon and flood disaster early warning model is not only suitable for a power distribution network, but also suitable for a power transmission network, considers the comprehensive influence of disaster-pregnant environment characteristic parameters, disaster-affected body characteristic parameters, disaster damage information and rainfall information, and provides guarantee for the safety and stability of the power grid.

Description

technical field [0001] The invention belongs to the technical field of power grid disaster prevention, and in particular relates to a typhoon flood disaster early warning method and device for a power grid. Background technique [0002] The power system is a huge and complex system involving multiple links such as generation, transmission, transformation, distribution, and utilization, and its safe operation is closely related to the meteorological environment. Among them, the distribution network is the main object vulnerable to flooding. Typhoon often triggers large-scale distribution line tripping, manifested as a large number of group faults, these faults may be instantaneous tripping faults or permanent equipment disasters, of which the proportion of the latter is relatively high. At the same time, typhoons are often accompanied by heavy rains, which affect the foundation of the tower, which may also cause the above-mentioned disasters, and may also cause waterlogging ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the disadvantages of low reliability of early warning information in the prior art, poor emergency response capability of power grid typhoon and flood disasters, low material allocation efficiency and large losses, the present invention provides a method and device for early warning of power grid typhoon and flood disasters, based on mesoscale numerical values The forecast mode obtains precipitation forecast information; input the precipitation forecast information into the pre-built typhoon and flood disaster warning model of the power grid, and obtain the typhoon and flood disaster warning information of the power grid; the typhoon and flood disaster warning model of the power grid uses the pre-designed typhoon and flood disaster forecast grid and The characteristic parameters of the forecast grid are determined, and the obtained typhoon and flood disaster early warning information of the grid has high reliability, which ensures the strong emergency response capability of the grid typhoon and flood disaster, high material allocation efficiency, and reduces losses
