摘要
现代化基础设施体系政策提出后,对交通、水利、能源和以信息通信为代表的新型基础设施建设提出了新的要求.各行业从基础设施发挥的效能出发,提出了布局结构功能和系统集成的优化方向.从研究现代化基础设施体系的功能作用出发,分析了电网基础设施在现代化基础设施体系中的重要角色,采用皮尔逊相关系数研究了电网基础设施线路长度和变电容量规模与全社会用电量的关联关系,并对2025、2035年东部、中部、西部、东北地区及跨区输电线路长度和变电容量规模进行预测,在此基础上分析了电网基础设施在现代化基础设施体系框架内布局结构功能和系统集成优化的逻辑,给出了构建现代化基础设施体系对电网布局结构功能和系统集成优化的需求,为电网基础设施的投资和建设提供参考.
Abstract
After the modem infrastructure system policy was put forward,new requirements were put forward for the construction of transportation,water conservancy,energy,and new infrastructure represented by information and communications.Starting from the effectiveness of infrastructure,various industries have proposed optimization directions for layout,structure,function,and system integration.This article starts from the study of the functional role of the modem infrastructure system,analyzes the important role of the power grid infrastructure in the modem infrastructure system,and uses Pearson's correlation coefficient to study the relationship between the power grid infrastructure line length and transformer capacity scale and the electricity consumption of the whole society.The article also forecasts the length of transmission lines and transformer capacity scale in the eastern,central,western,northeastern,and other regions in 2025 and 2035.On this basis,the layout,structure,and function of the power grid infrastructure within the framework of the modem infrastructure system are analyzed,and the logic of system integration optimization is given.In addition,the requirements for power grid layout structure function and system integration optimization in building a modern infrastructure system are put forward,providing a reference for the investment and construction of power grid infrastructure.This work is supported by Science and Technology Project of SGCC(Research and Application of Key Technologies for Comprehensive Risk Prevention and Control of Power Supply and Demand Balance in the Power Market Environment,No.5108-202218280A-2-429-XG).
