Abstract

The embodiment of the present invention relates to a distribution transformer load stratification prediction method and device based on neural network, including data acquisition processing, sample classification, establishment of BP neural network model, data selection and normalization processing, establishment of CNN neural network model and In the six steps of outputting forecast results, the BP neural network model and CNN neural network model constructed by the historical load data of the previous 4 years and the attribute information data of distribution transformers decompose the direct load forecasting into trend forecasting and numerical forecasting, which is convenient in Under different levels of information acquisition, the trend judgment accuracy or numerical judgment accuracy can be improved according to the data quality and information richness, and the existing load prediction method for distribution transformers is solved due to the small power supply area and large power load fluctuations. Inaccurate results due to technical issues.

Description

technical field [0001] The invention relates to the technical field of distribution transformer loads, in particular to a neural network-based distribution transformer load layered prediction method and device. Background technique [0002] In recent years, there have been more and more smart distribution networks. Effective management of various smart devices in the smart distribution network can promote the construction of smart distribution networks and improve the level of power grid operation and management. In the context of implementing the unit system, refined planning, and operation and maintenance of the distribution network, load forecasting based on the low-voltage station area is of great importance for grid load development trend and planning demand analysis, distribution network weak link identification, and power system analysis. Operation mode adjustment and other businesses are of great significance. [0003] With the popularization of on-line monitoring e...
