Abstract: With the continuous highlighting of global carbon emissions issues, zero carbon city planning and carbon platform technology innovation have become key ways to solve energy and environmental problems. This paper proposes a construction plan for a zero carbon substation system based on the concept of zero carbon city planning and the application of carbon platform technology. Through comprehensive diagnostics of substation operational challenges, this study develops an integrated system architecture incorporating visualization interfaces and optimized field equipment configuration, strategically designed to advance infrastructure sustainability in zero-carbon urban ecosystems. By analyzing the expected effects of zero carbon substation systems, this paper aims to provide technical support and theoretical guidance for promoting the construction of zero carbon cities.
