输电线路建设和运行中的制约与技术创新

为了应对目前我国电网在建设和运行中面临的土地资源紧张、运行环境恶劣等制约因素,分析了新型输电线路技术、线路设备的新材料和新工艺、线路设计中的新方法和新措施、线路运行维护新技术等输电线路技术创新的特点和优势,提出提升单位走廊输送能力、增强线路本体抵御自然灾害的能力、提高线路运行维护水平应成为输电线路建设的方向。在电网的建设和运行中,结合工程实际采用技术创新,对建设"资源节约、环境友好的坚强电网"具有重要意义。

Restriction and Technological Innovation in Construction and Operation of Power Grid

In order to answer the restrictive factors in construction and operation of power grid,the features and advantages of technological innovation in transmission line was analyzed in this paper,which include new power transmission technologies,new materials and processes of line equipment,new methods and measures of line design,new operation and maintenance technologies of line ect. It is putted forward that,increasing the power capacity per unit corridor area of line,enhancing the ability of line body to resist natural disaster,improving the level of operation and maintenance of line,should be the direction of transmission line construction. The using of these technological innovation in the construction and operation of power grid,has important significance for constructing "resources-saving,environmentally-friendly and strong power grid".
