Power grid high low temperature refined early warning method in combination with dynamic correction

Abstract

The invention discloses a power grid high low temperature refined early warning method in combination with dynamic correction, comprising the steps of: S1, forecasting local weather to generate highest and lowest temperature forecast results and extracting live weather factors influencing local temperature forecast results; S2, establishing highest and lowest temperature forecast equations in dependence on generated temperature forecast results and selected live weather factors; S3, counting highest and lowest temperature forecast errors based on actually measured highest and lowest temperature information and forecast results, and correcting the highest and lowest temperature forecast results based on the temperature forecast errors to obtain final forecast results of highest and lowest temperatures; and S4, performing electric power equipment priority forecasting based on the final forecast results of highest and lowest temperatures and publishing early warning information. The power grid high low temperature refined early warning method can effectively solve the problem of great differences between a power grid system high temperature and low temperature forecast effect and an actually measured result, timely and effectively take corresponding measures to cope with extremely high and low temperatures, and mitigate damage caused by extreme weather.

Description

technical field [0001] The invention relates to a high and low temperature early warning method, in particular to a high and low temperature refined early warning method for a power grid combined with dynamic correction, and belongs to the technical field of meteorological disaster prediction. Background technique [0002] In the context of global warming, the frequency and intensity of meteorological disasters caused by extreme weather and climate events are increasing. With the rapid development of my country's power grid scale, the power grid is also severely damaged by meteorological disasters such as typhoons, heavy rain and snow, lightning, and strong winds. The impact of extreme high and low temperature weather processes and seasonal changes on social electricity consumption is increasing. [0003] Sustained extreme high temperature and extreme low temperature will cause the deterioration of the working environment of power transmission and transformation equipment, a...

Problems solved by technology

[0005] However, in the power grid system, there are still problems such as low resolution of high temperature and low temperature forecasting of the power grid system, and the large difference between the forecast effect and the actual measurement. Before the occurrence of extreme high temperature and low temperature, timely and effective measures should be taken to reduce or even prevent the occurrence of damage
