Unified Platform Power Dispatching Data Network Design

With the power grid management mode and the management level unceasing enhancement, the electric power dispatching business plays a more and more important role, which becomes an important technical measure of ensuring grid safty, stability and economic operation. But power dispatching data business transmission continues traditional digital line mode, such channel mode is not conducive to information sharing, and it also creates waste of communication resources. Along with the grid development,succession online of various scheduling business, more and more urgent for grid data sharing and channel resources sharing demands.Based on the electric power dispatching data business transmission of Zhengzhou as an example, this paper introduces the current status, analyzes the dispatching data business information flow and existing problems, this paper expounds the necessity and feasibility of establishing the scheduling data networks. power dispatching business system exists respective features, such as dispatch automation system transmits real-time data flow, but measuring system transmits non-real-time data flow, according to the characteristics of these business system, combining safety requirements,choice VPN technology business safe and reliable transmission of data. In view of the technical contrast of current commonly used two VPN plans:IPSec VPN and MPLS VPN, BGP/MPLS VPN is finally choiced as a main techniques to construct scheduling data network..Power dispatch data networks is a information digital network which is based on optical fiber transport network of SDH, it devides VPN of real-time business and non-real-time business in scheduling data network,guarantee the different types of business system logic isolation. The paper reviews the core and the backbone of dispatching data network, network structure design of the three layers, the specific application of MPLS VPN technology in dispatching data networks, Using the QOS technology to guarantee service quality of different types of business, the paper designs safe protection of dispatching data networks and network management,detailed access planning design of various dispatching data business, finally made a prospect to dispatching data networks.Electric power dispatching data network radically changed the traditional point-to-point information transfer mode, and provided the foundation for fully develop of production scheduling information resource and configuration optimization, provides a network platform each system based on to share information and exchange data.
