The demand for lean management of distribution network is growing. However, the current identification of distribution network data quality lacks a unified standard and cannot achieve automatic data verification and processing, which restricts the improvement of distribution network application level. In the actual distribution network application, more experts rely on their experience to solve the quality and availability problems of local distribution network topology data as needed, lacking a global data quality evaluation and solution. With the development of smart grid, the demand for lean management of distribution network is growing. However, the current identification of distribution network data quality lacks a unified standard and cannot achieve automatic data verification and processing, which restricts the improvement of distribution network application level. In actual distribution network applications, more experts rely on their experience to solve the quality and availability problems of local distribution network topology data as needed, Lack of overall data quality evaluation and solutions. This paper first combs the status quo and quality problems of distribution network topology data, collates and summarizes the current status quo of distribution network topology data, summarizes the problems existing in the application of distribution network topology data, and researches and classifies the problems, laying a foundation for the development of distribution network topology data quality evaluation system and distribution network topology data verification rules.
