Abstract

The invention provides a power-transmission-line anti-typhoon early warning method and a system thereof. The method comprises the following steps of acquiring wind field distribution information of typhoon; acquiring a position and structure information of a power transmission line which is about to be invaded by the typhoon; according to the position and the structure information of the power transmission line, and the position of the typhoon and the wind field distribution information, carrying out structure dynamics analysis on the power transmission line so as to carry out risk assessment and forecast on a damaged degree of the power transmission line. In the invention, a technical problem that risk assessment and forecast can not be performed on the damaged degree of the power transmission line because of a typhoon influence in a correlation technology is solved, and the risk assessment and the forecast of the power transmission line which is influenced by the typhoon are realized.

Description

technical field [0001] The invention relates to the field of computer simulation forecasting systems, in particular to a typhoon prevention and early warning method and system for transmission lines. Background technique [0002] In recent years, frequent typhoons in coastal areas have brought serious losses to the power grid, especially under the action of strong typhoons, resulting in catastrophic damage to transmission lines along the way, seriously affecting the stability of power grid operation. [0003] At present, some researches on power grid meteorological disaster monitoring have been carried out in China. These monitoring systems can monitor the meteorological conditions of different stations in the power grid geographic information system (GIS) in real time and send out forecast signals for different meteorological conditions. However, these systems only forecast the weather conditions in the area where the transmission line is located, without considering the me...
