In response to the industry pain point of recurring quality defects in power engineering design

Central Southern China Electric Power Design Institute Co.

Ltd.has innovatively established a management system for a design quality defect database.This system achieves a shift from passive rectification to proactive prevention of design quality defects through a three-phase control process:standardized classification

dynamic database updating

and intelligent early warning.This paper systematically elaborates on the architectural design of the quality defect database system

the practice of full-process digital management

and its multidimensional value effects

forming an innovative paradigm for power engineering quality management with industry-wide value.It provides quality assurance support for the construction of new power systems.Empirical data show that after the implementation of this system

the company's product excellence rate has continuously improved

project rework rates have declined

and significant engineering and social benefits have been achieved

creating a replicable new model for power engineering quality management.
