The invention discloses a thunder and lightning early warning research and judgment method based on a multi-element dynamic weight algorithm. The method comprises the following steps: S1, extracting basic information of a power grid, thunder and lightning division data and thunder and lightning disaster data of the power grid; s2, processing the power grid basic information, the thunder and lightning division data and the power grid thunder and lightning disaster situation data into an input data format suitable for an early warning grade model; s3, combining the basic information of the power grid, the thunder and lightning division information and the thunder and lightning disaster information of the power grid, and dynamically adjusting thunder and lightning forecast adjustment parameters on different grid points for different power grid environments; and S4, extracting thunder and lightning forecast data, correcting the thunder and lightning forecast data by using the thunder and lightning forecast adjustment parameters on the different grid points obtained in the step S3, and generating final thunder and lightning early warning research and judgment information. The method provides guarantee for safe operation of the power grid, provides technical support for active defense of lightning damage of the power grid, reduces lightning damage loss of the power grid, improves operation and maintenance efficiency of the power grid, and has great significance for guaranteeing safe and stable operation of the strong and smart power grid.
Description
technical field [0001] The invention relates to the technical field of lightning early warning technology, in particular to a lightning early warning research and judgment method based on a multi-element dynamic weight algorithm. Background technique [0002] Lightning is a spectacle created by nature, and the power transmission network is the crystallization of human wisdom. However, lightning disasters are also one of the natural disasters that have the greatest impact on the power grid. With the increase of power system capacity and the continuous development of power grid construction, especially for long-distance and large-capacity power transmission, the safety status of its transmission lines often directly affects the safety and stability of the entire power grid. Threats to the security of the power grid such as lightning disasters are also becoming more and more serious with the construction of the power system, and the number of power grid accidents is also on th...
