Research And Application Of The Second Plane Dispatching Data Network In District Dispatching

With the establishment of “three sets of five major”, “Scheduling and monitoring” will be come true gradually In city level dispatching center, 220 kV and110kV substation will be centralized monitoring, and power transmission equipment state will be on-line monitoring. In country level dispatching center, 35 kV substation will be centralized monitoring. In order to meet the needs of power grid development,and meeting Scheduling mechanism for scheduling information needs in Normal state or emergency state. At the same time, to provide reliable technical support for the backup scheduling and construction of smart grid dispatching technology support system, and comprehensively improve the network reliability and operational support capacity, construction of the second plane electric power dispatching data network is very important. As the most important work of automated operations, the construction of the second plane electric power dispatching data network, and completing full coverage of city and country level dispatching center and 35 kV substation or more than 35 kV substation is guarantee of improving the power grid running safety and reliability. This paper introduces the present situation of electric power dispatching data network and the requirement of the second plane at first, with analyzing actual situation and business requirements, proposes overall plan of the second plane electric power dispatching data network, technological regimes, the principle of public resource allocation, security policy and network management system, giving a prospect of the second plane electric power dispatching data network and analysis the application conditions and technical difficulties at last.
