Abstract

Along with gradual promotion of intelligent substation construction, a virtual secondary link is difficult to be positioned to a physical link in an intelligent substation at present, and a physical transmission path cannot be positioned accurately and quickly when secondary virtual links such as goose, sv and the like break down, thereby resulting in lagging of troubleshooting. The invention discloses a topological mapping method for secondary virtual and physical links of an intelligent substation. According to the invention, a mode of a corresponding relation of the secondary physical links and the secondary virtual links is generated through carrying out extension on an SCD file, a topological search algorithm is provided, and positioning for a path of the transmitted physical link is realized by the virtual link through a method of traversing port spanning trees. The topological mapping method provided by the invention is not affected by network architecture of the substation, a single network, dual networks or the like, and has very high universality.

Description

technical field

[0001] The invention belongs to the technical field of intelligent substation automation. In particular, it relates to a topology mapping method for secondary virtual and real links of smart substations. Background technique

[0002] In traditional substations, the secondary circuit is based on point-to-point cable information transmission, the information of the transmission channel can be monitored, the status of the channel is also known, and there is no so-called virtual link. In smart substations, the secondary loop is changed from hard-wired to virtual loop, and optical fiber loops are used to share data communication information at the process level.

[0003] The architecture of the secondary circuit in the smart substation can be subdivided into direct mining and jumping, direct mining and network jumping, network mining and network jumping, etc. Under the network architecture of direct mining and direct jumping, since the virtual loop and the actua...
