A Primary Investigation Of The Capacity Expansion And Reformation Based On The ACCC Core

With the development of power grids, the electric power demand increases quikly, the transmission ability of transmission lines can not satisfy the increasing electric power demand. As a kind of transmission lines, the aluminum conductor steel reinforced(ACSR) has limitation on the improvement of transmission ability. Zhejiang power grids attempt to use aluminum conductor composite core(ACCC) inplace of aluminum conductor steel reinforced(ACSR), and it gets good benefit in the transmission lines enlarging capability and rebuilding. However, the application of ACCC in power grids is in initial stage, technologist and project planner are not familiar with characteristic of this new type line. It is necessary to do research on the technical characteristics of ACCC in power grid project. Also the problem in the process of construction,operation and maintenance should be pay much attention to, the settlement of these problems will have guide effect for transmission lines rebuilding.This paper generalizes the development and application of ACCC in electric power project, according to transmission lines rebuilding of zhejiang power grids and experience. It explains the design technical requirement of ACCC, and does research on construction,operation and maintenance of ACCC based on standardization,normalization and informationization management. Although the operation experience of ACCC is lack, the author thinks it is useful to accumulate and manage the transmission operation data perfectly, comprehend the operation standards deeply, work out the enterprise standard of ACCC operation and maintenace, accomplish ACCC operation and maintenace with production management system(PMS).
