Research on Construction of Region Dispatching Access Network for Electric Power Dispatching Data Network

Along with the gradual strengthening of application levels and function needs for the power secondary system,the strong smart grid with informatization,digitization,automation,and interaction puts forward the higher requirements for the reliability and carrying capacity of electric power dispatching data network.It focuses on the access network topology,convergence layer node design,VPN deployment and IP address planning through analyzing the present situation of dispatching data network.At the same time,this paper proposes a conception of access network of electric power dispatching data network based on the structure of communication network.
