Abstract

The invention relates to the technical field of power grid strong wind early warning, and discloses a power grid strong wind safety early warning management and control method and system, and the method comprises the steps of obtaining a strong wind prediction data set of a region where power grid equipment is located in set time; rendering each strong wind forecast data according to the wind speed grade, and superposing and correlating the strong wind forecast data with the power grid equipment geographic information graph to obtain a superposing and correlating graph layer; and determining corresponding line tower strong wind early warning information according to the superposition association layer and the geographic information of each line tower. According to the invention, the geographic information of each line tower is combined with the strong wind forecast data of the corresponding area to generate the line tower strong wind early warning information meeting the actual situation, so that the line tower strong wind early warning precision is effectively improved, accurate early warning support is provided for operation and maintenance personnel, and normal operation of a power grid is ensured.

Description

technical field [0001] The invention relates to the technical field of high wind early warning for power grids, and relates to a method and system for early warning and control of high wind safety for power grids. Background technique [0002] Power transmission and transformation equipment is spread all over the field, with complex terrain and changeable meteorological environment. Some power transmission and transformation equipment will pass through areas with harsh environments such as strong wind areas. Power outage. Since there is no professional weather forecasting organization in the electric power industry, weather information needs to be obtained from the public meteorological department, so it is impossible to obtain weather warning equipment information and make emergency preparations such as inspections in advance. Therefore, inspection and maintenance of power grid equipment and fault finding can only rely on operation and maintenance experience, which costs a ...
