Refined Meteorological Forecasting of Power Grid based on Numerical Analysis

Meteorological disasters were one of the natural factors that were most likely to cause serious accidents in the power grid, so the demand for the accuracy, accuracy and timeliness of meteorological service early warning in power grid production was becoming more and more urgent. In order to improve the ability of the power grid to resist severe weather, a refined meteorological forecasting of the power grid based on numerical analysis was proposed, which can realize the refined meteorological forecast of the area near the power grid, which provides data support for the meteorological disasters of the power grid. Based on the regional numerical prediction products, the forecast of meteorological elements in a certain area was obtained, and the dynamic downscaling technology was used to eliminate the influence of the difference between specific terrain and obstacles on the meteorological data. Through the statistical analysis of historical samples and the real-time forecast error was introduced as a correction factor, the forecast accuracy of regional meteorological elements near the power grid was improved. An example was given to verify the feasibility of refined meteorological forecasting of power grid based on data analysis and provide data reference for power grid meteorological disasters.
