Abstract

The invention discloses a power grid weather predicting and early-warning system based on a numerical weather prediction model. The power grid weather predicting and early-warning system comprises a numerical weather predicting system, a micrometeorological data collection system, an MOS predicting system and a weather predicting system, the micrometeorological data collection system is connected with the MOS predicting system, the numerical weather predicting system is connected with the MOS predicting system and the weather predicting system, the MOS predicting system is connected with the weather predicting system, and the weather predicting system is used for conducting predicting, early-warning, querying, counting and analyzing on weather phenomena of an area under administration and providing a visualized graph interface by taking data obtained by the numerical weather predicting system and data obtained by the MOS predicting system as bases. The power grid weather predicting and early-warning system based on the numerical weather prediction model has the advantage that quantitative prediction can be conducted automatically without relying on external numerical weather predictions.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to a power grid weather forecasting and early warning system based on a numerical weather forecasting model. Background technique [0002] In order to effectively detect meteorological disasters in the power grid and ensure line safety, the line status monitoring system has been widely used and accumulated a large amount of monitoring data. On the one hand, these data can be used for real-time diagnosis to grasp the current status of transmission lines, and on the other hand, they can be used to evaluate history and estimate the probability of regional meteorological disaster risks. However, the current public weather service and power grid weather information service system cannot meet the actual needs of transmission line operation and maintenance, mainly in the following aspects: the temporal and spatial resolution has not yet been refined to the extent required...
