| Currently Ningxia regional power grid system,110kV substation mostly hand in hand ring mesh wiring, but the use of open-loop operation mode. Conventional device considering the configuration of the station bus coupler and into the line only at the point of realization of the open-loop automatic switching function, when the power line failure will cause the intermediate substation contact line Loss of Pressure, prepared from Investment means not play a role to ensure a reliable power supply cut fault line on the grid system cause greater risk.In this paper, through the substation with remote device considering to ensure reliability of supply. Carried out on the basis of a conventional device considering the upgrading of special device considering the characteristics of hand in hand for the power grid structure and design, through two 110 kV substations within a set distance each installed device considering, That device considering adding prepared from the cast remote communication devices. Substation sides prepared from the cast remote device via optical fiber communications, configure Fibre Channel to time mode, enabling the two sides prepared from the cast reception and transmission function of the device. Two devices with each other in order to achieve remote automatic switching function. Wen will Wuzhong area 110kV grid system as the research instance analysis identified several new substation operation mode, analyzes and compares the action logic and functional configurations in different operation modes remote device considering, reflecting the distance prepared from Investment means the application of the superiority of the grid structure, reducing the risk of grid operation in existence, with a high research and application. Wuzhong become a regional power grid is currently the second remote device considering the application, so the application has a good practice guidance for the wide range of applications accumulated operational experience better future. |
