Key Technology Research of Distribution Automation System Based on Cloud Architecture

摘要

China's economic development has higher requirements for the power supply capability and reliability of distribution network. At present, the management scope of distribution automation system cannot cover the whole distribution network and many regional electric companies cannot manage the operation state of distribution network through the existing distribution automation system, which restricts the development of distribution network construction. It is necessary to develop a new system construction scheme to cope with the different data capacity and function requirements of distribution networks in different cities. This paper proposes a technical scheme of main station of distribution automation system based on cloud architecture in aspects of system architecture, elastic data processing, safe access of distribution terminals and optimal operation control. With the distributed collaboration between core cloud and regional cloud as well as data fragmentation parallel processing technology, the problem of massive access and application of distribution network will be solved.
