Construction scheme of power dispatching exchange network in city-level

Based on the current status of dispatching switch network in Nanjing Power Supply Company and the technical specification for dispatching switch network, a transparent, star structure dispatching digital exchange network was built in Nanjing Power Supply Company. This paper introduces the construction scheme, emphasizes on the realization of extension for dispatching table to a different place and setting dif- ferent dispatching tables in a group. This scheme can improve the reliability and utilization ratio of channels in dispatching switch network and satisfy the need of power grid development.
