As the link of the energy and electric power system

the effective state evaluation of the power equipment is a powerful guarantee for the stable operation of power system. Based on the existing research results and the perspective of data science

this paper makes an in-depth analysis of the methods in the field of state evaluation of power equipment. Firstly

the paper introduces the new characteristics of state evaluation of power equipment in the context of data science. Then

with the current well-known data science analysis method based on data analysis technology as the starting point

the paper presents the key issues of the state evaluation of power equipment in data preprocessing

calculation and analysis

storage

and visualization. In addition

the paper systematically expounds the specific application

bottleneck and future development of data science in the field of state evaluation of power equipment. Finally

the paper discusses the challenge of data science in the state evaluation of power equipment and anticipates some directions of future research work in this field.
