Photovoltaic Transformer Economic Optimization Solution: Key Pathways for Cost Reduction and Efficiency Enhancement
Ⅰ. Problem BackgroundIn photovoltaic power stations, containerized step-up transformers (referred to as “PV transformers”) account for approximately 8%–12% of total equipment investment, while their losses exceed 15% of the station’s total losses. Traditional selection methods often overlook lifecycle cost (LCC), resulting in hidden economic losses.Ⅱ. Core Economic Challenges High Initial Costs• Significant price premiums for high-end imported equ
