Problems solved by technology

[0002] The smart substation adopts the IEC61850 standard, and uses the GOOSE method to realize the information interaction between the devices, tripping and closing the exit, etc., replacing the cables in the traditional substation, so the on-site installation workload is greatly reduced compared with the traditional substation, but in the joint commissioning stage The workload has increased, and problems often occur due to wrong connection of virtual terminals during debugging
At present, the virtual terminal relationship table provided by design institutes in various places does not have a unified format specification requirement, and the same virtual terminal connection is often marked on the sending end device side and the receiving end device side. This kind of information duplication is not conducive to the commissioning personnel of the substation Debugging and recording according to the virtual terminal relationship table

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0017] like figure 1 Shown is a schematic flow chart of the present invention. The present invention provides a method for deriving the virtual terminal connection of the smart substation without repetition according to the device, and specifically adopts the following steps:

[0018] The first step: the intelligent substation auxiliary debugging tool software (hereinafter referred to as the tool) reads the SCD file of the intelligent substation;

[0019] Step 2: The tool reads the organizational level file that stores the voltage level, interval, and device information of the smart substation that is matched with the SCD file;

[0020] Step 3: The tool marks the connected receiving virtual te...

Abstract

The invention discloses a method for exporting full-substation virtual terminal connection of an intelligent substation by devices without repetition and belongs to the technical field of electric power automation. The method comprises the following steps: SS1, importing an SCD file and an organization level file of the intelligent substation; SS2, marking connected receiving virtual terminal for the sending virtual terminal of each device; SS3, verifying whether the virtual terminals of each device are connected or not according to the scanning rule, extracting the information of the virtual terminals according to an information extracting rule for the connected terminals, and meanwhile, recording device and interval information related to virtual terminal connection; SS4, exporting the extracted and recorded information related to the virtual terminal connection in the step SS3 by the devices according to an exporting rule, and organizing exported information according to voltage grade and intervals. The exporting automation of the full-substation virtual terminal connection relation is realized, and no virtual terminal connection is omitted when repeated connection information is eliminated.
