Power generation engineering is an important part of the engineering field, covering a lot of knowledge, focusing on converting other energy into the electrical energy needed for people's life and production, so as to better serve economic growth, social progress, human development, etc. With the deepening of power generation projects and related research in recent years, the technical and economic data generated by power generation projects have shown the characteristics of diversification and quantification. These technical and economic data are mainly recorded through word and excel, and the effective application of data governance to power generation projects can quickly and accurately extract valuable data from massive technical and economic data, so as to provide data support for power generation engineering research, design, operation, management, etc., so that power generation projects can be optimized and developed.
