Design and Implementation of a Computer-Aided Full Lifecycle Quality Management System for Wind Farms in Upgrades, Renovations, and Subcontractor Supervision

Wind farms often undergo large-scale upgrade and renovation projects throughout their operational lifecycle, requiring close coordination with multiple subcontractors. This paper proposes a computer-aided full lifecycle quality management system that integrates digital technologies such as process control engines, multi-dimensional KPI computing models, version-controlled document repositories, and real-time data-driven risk assessment algorithms. The system provides end-to-end governance over planning, construction, operation, maintenance, and retrofitting phases. Core modules include a computationally driven responsibility matrix, Git-based technical documentation platform, algorithmic subcontractor performance scoring, and data-informed risk mitigation modules. Experimental validation across five upgrade projects and three long-term O&M cases demonstrates a 20%–35% reduction in defect occurrence, a 30% decrease in rework hours, and improved consistency in project delivery and client satisfaction. The research highlights the value of integrating computer technologies to enhance wind farm lifecycle quality control and support intelligent project governance.
