However, it is often difficult for gridded forecasting products to take into account geographical factors, power grid factors, and meteorological factors at the transmission line tower, and there are certain errors between the predicted data and the actual rainfall monitoring data, which leads to the accuracy of gridded forecasting products. Not so high that it is difficult to support the disaster prevention and mitigation of the power grid

The invention belongs to the technical field of power grid power transmission line tower rainfall prediction, and provides a power transmission line tower rainfall correction method and device based on error statistical analysis. The power transmission line tower rainfall correction method based on error statistical analysis comprises the following steps: acquiring rainfall monitoring data at power transmission line towers at a plurality of historical time points and rainfall prediction data at corresponding historical time points, and calculating a rainfall error value; acquiring information data of each power transmission line tower at the corresponding historical time points, and carrying out normalization processing on the information data to obtain feature data; enabling the feature data and the rainfall error values to form sample data in a one-to-one correspondence manner; carrying out training testing on a regression model through employing the sample data, and obtaining a rainfall correction model; and correcting the rainfall prediction data at a to-be-predicted tower through employing the rainfall correction model. According to the transmission line tower rainfall correction method based on error statistical analysis, the rainfall prediction value of the existing transmission line tower level is effectively corrected, and the accuracy of rainfall prediction data is improved.
Description
technical field [0001] The application belongs to the technical field of rain forecasting of power grid transmission line pole towers, and in particular relates to a method for correcting transmission line pole tower rainfall based on error statistical analysis. Background technique [0002] Overhead power transmission is the main mode of power resource supply in countries around the world. Transmission lines are widely distributed and located in complex geographical environments. They are always threatened by wildfires, landslides, mudslides and ice cover. Rainfall has a greater impact on the above-mentioned natural disasters. The transmission line tower is a key component of the transmission line system. It is responsible for bearing the force of the transmission wire and the ground wire, and keeps a certain safe distance between the wire, the earth and the tower. Its stability is an important guarantee for the operation safety of the entire transmission line. , so the rai...
