Practical Study on Low-Carbon Energy-Saving Renovation of 220kV Operational Substation

This study investigates the low-carbon renovation of a 220 kV operational substation in Guangzhou, focusing on analyzing electricity consumption patterns, identifying energy-saving opportunities, and validating renovation strategies. Through optimized operation of air conditioning, ventilation, and lighting systems, equipment upgrades, and the integration of photovoltaic (PV) power generation, the substation achieved significant reductions in energy consumption and carbon emissions. The findings provide actionable insights and theoretical support for the green transformation of operational substations, advancing sustainable development in the power sector.
