Analysis And Planning On Electric Power Dispatching Data Network Of Yingtan

Electric power dispatching data network is a wide area network based on communication transmission network, which have route, exchange and business access abilities. It is a comprehensive electric power dispatching information transmission platform and important facilities which can realize data transmission between at levels of dispatching center, control center and factory stand.Firstly, this paper introduces the development status and the existing problems of electric power communication network and electric power dispatching data network. Secondly, it conducts the in-depth research and analysis on business requirements, technical system, routing strategy, function of the network, network performance, network security and network management. Lastly, it put forward the principle of network construction and network optimization scheme.The paper takes Yingtan network for an example, use the mature、advanced network technology construction scheme which can improve network application level. It constructs the Yingtan electric power dispatching data network which have high flexibility, adaptability and good expansibility. This platform can use network to drive the development of application and promote development of network. Finally, it can establish a sustainable development strategy.In this paper, the main research has the following features:(1) The core, backbone layer uses dual equipment, dual power supply redundancy configuration, it can effectively avoid the single point of failure.(2) The core, backbone layer uses155M CPOS networking mode, it can meet the power grid dispatching business expansion need.(3) All business use MPLS VPN to access, it can improve the security of data transmission and the quality of service.
