Based on the current situation and existing problems of energy consumption data of construction machinery platforms of power grid construction projects, the energy consumption data system of construction machinery platforms of power grid construction projects is constructed by referring to the current standard/normative data structure and basic principles of the national level, power industry and other industries, and combined with the actual situation of power grid construction projects. This paper studies and puts forward the method of compiling energy consumption data of construction machinery platform in power grid construction project, and finally verifies the feasibility of the proposed theory and method through engineering examples.
