Power generation engineering is a traditional industry in China, and the digital process is relatively lagging behind. At present, BIM related technologies are rarely applied in the research feasibility, design stage, construction stage, acceptance stage, operation stage and maintenance stage and other stages of power generation engineering projects. Based on BIMBase, a 3D graphics platform engine made in China, this paper proposes and verifies a method for deepening quality inspection of power generation engineering life cycle data according to series data specifications and delivery specifications of power generation engineering. Through processes of data integration, built-in standards, engineering verification, data repair, and results export, the power generation project can be realized in a systematic, streamlined, standardized and automatic quality check, which can effectively improve the checking efficiency and reduce the error rate. The quality inspection and delivery tools provided in the paper can be applied to the entire life cycle of the engineering information model to ensure that the owner receives the high-quality information model and lay the data foundation for application during construction and operation.
