Embodiment Construction

[0027] In order to make the technical means realized by the present invention, creative features, goals and effects easy to understand, the following will further elaborate the present invention in conjunction with specific embodiments, and the examples described below are only some examples of the present invention, rather than all examples.

[0028] Currently used in SCD files To describe the access control blocks of station control layer and process layer in the whole substation, the mapping between these control blocks and physical links is incomplete. In this implementation, the ports of IED equipment and switches are extended to Get all physical paths of the control block. Proceed as follows:

[0029] 1. IED device physical port modeling. in the SCD file The field contains the single physical port information of all IED devices, and the IED device name is in It can be obtained from the properties of under The node can get all the port descriptions in the IED,...

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...
