This paper designs and implements an energy management platform for the entire lifecycle of green computing centers in response to the increasingly prominent energy consumption issues.Through in-depth analysis of business requirements in three key stages planning

design

and operation a comprehensive management platform covering green energy planning

energy-saving design

and green energy utilization is constructed using microservice architecture.The platform realizes key functions including precise calculation of specification parameters based on multi-dimensional variable parameters

simulation equipment component library management

and real-time monitoring with intelligent analysis.Validation through typical application cases shows that the platform can effectively improve management efficiency and energy efficiency throughout the lifecycle of computing centers

providing ective technical support and management tools for green transformation.
