Design And Implementation Of Protection And Supervisory For66kv Smart Substation

With grid technology continues to improve, New ideas have been proposed andapplied to the substation power grid construction. As an important node in the gridsubstations, the must assume the role of a pioneer. In such an environment, developmentand implementation of intelligent technology in substation construction, State GridCorporation of China has promulgated a relevant technical implementation specification.Intelligent substation according to the network structure is divided into: station level,process level and the spacer layer. By and comparing conventional substation, Thisarticle from the monitoring, remote configuration and other conditions, station levelnetworking of the system, the process level networking and other non-intelligent IEDdevice access methods in these areas, Discuss the application and implementation ofintelligent technologies. Combined with field experience, discuss clock synchronizationabnormal system operation, and switching voltage parallel implementation, Equipmentmaintenance strategies and electronic transformer applications.This article also describes66kV substation intelligent, principle of protectionfunctions, configurations and applications. Meanwhile, there is an introduction ofintelligent substation commissioning process and the problems which need to beaddressed.Finally, this paper on intelligent technology applications in the power grid madesome of their own views and outlook. As a product of the times, it will have betterdevelopment.
