With urbanization and urban power grid construction,the number of substations is gradually increasing,and under the national goal of"carbon peaking and carbon neutrality",new requirements have been put forward for the green construction of substations.This paper takes the whole process construction of substation as the research object,combines the existing relevant evaluation standards,and constructs a green construction evaluation system applicable to the whole construction process of substation,including 4 primary indicators of green planning,green design,green construction and green delivery,13 secondary indicators and 68 specific evaluation rules.Then the corresponding indicator weights and the score calculation methods were determined by AHP method.This system can be used to guide the whole green construction process of the future substation projects.
