Description

【Technical field】 [0001] The invention belongs to the field of distribution network, and in particular relates to a system for improving the quality of massive data in a distribution network. 【Background technique】 [0002] The distribution network is at the end of the power system, and has the distinctive characteristics of wide geographical distribution, large-scale power grid, various types of equipment, and diverse network connections. With the increasing level of distribution network informatization, various information systems in the distribution Power grid operation status and business applications provide a wealth of data, including internal data such as distribution automation, scheduling automation, and production management systems, as well as external data such as natural environment and social economy, and involve distribution network planning, Operation and maintenance and other links. Distribution network data has the following characteristics: (1) There are ...

AI Technical Summary

Problems solved by technology

Distribution network data collection is large, with different time and space scales, incomplete data, diverse data structures, errors and leakage, so the data quality problem of distribution network is a common and prominent typical problem

Although major breakthroughs have been made in the research of distribution network data-intensive basic analysis, intelligent auxiliary decision-making, and high-performance parallel optimization calculations, the problem of "weakness in the middle" of distribution network data transmission has not been resolved.
