A design method for wide-area operation and maintenance architecture of substation automation equipment

Abstract

The invention discloses a design method for a wide-area operation and maintenance framework of substation automation equipment, which establishes an information highway that can freely transmit various application data between the main station and the substation, including a public service layer, a general service layer and an application service layer , the application service layer is located on the main station side, through the dispatching data network and the remote operation and maintenance system of the remote operation and maintenance center of the application service layer, the remote operation and maintenance of public services on the substation side is realized. The remote operation and maintenance system on the main station side adopts service-oriented The application mode, based on the remote interaction technology of general services, accesses the communication services, model services, graphics services, point table services and other content of each substation on the substation side, which can be used to realize remote wake-up, remote reset, Integrated remote maintenance such as forwarding table configuration, secondary device status indicator monitoring and diagnosis can also be used to realize remote operation control functions including forwarding table monitoring, channel and message monitoring, and remote desktop.

Description

technical field [0001] The invention belongs to the field of substation automation, and in particular relates to a design method for a wide-area operation and maintenance framework of substation automation equipment. Background technique [0002] At present, in the field of power system substation automation, the operation and maintenance of substation automation systems and equipment are mainly on-site operations. The substation has the characteristics of wide area, wide distribution of maintenance points, and many substation monitoring system manufacturers. The traditional on-site operation mode needs to travel to and from the substation site, which consumes too much time for the journey and short effective working time. With the expansion of the grid scale, the operation and maintenance of substation automation systems and equipment are under great pressure and many tasks, resulting in a heavy workload for front-line professionals. [0003] Therefore, how to use an effec...
