Embodiment 1

[0081] The constructed database has 160 SCD files and 344166 virtual connections.

[0082] For example, the current receiving device to be designed is a 220kV measurement and control device (its device code is CL22), and one of its sending devices is a 220kV intelligent terminal (its Equipment code IL22).

[0083] If the target association of the present invention is not adopted to the fast search optimization method, it is found that the speed of searching for the object association is particularly slow when the receiving device is a measurement and control device, running on a desktop computer configured with a 2.8G dual-core CPU, memory 4G, etc. It takes almost 10 minutes. The reason for its slow speed is that there are many relevant association pairs to be queried (446 pairs), and these same association pairs have a large number of template virtual connections (a total of 28,744), and the input virtual terminal of the receiving device "220kV measurement and control device...

Abstract

The invention discloses a Multi-SCD-oriented method for rapidly searching and optimizing target associated pairs of intelligent substations. The method comprises the following steps: respectively analyzing a plurality of existing SCD files layer by layer, and forming to-be-designed associated pair codes by utilizing each equipment code; aiming at a historical SCD database, filtering the same associated pairs which do not need to be processed and virtual connections thereof by adopting a filtering strategy; comparing input virtual terminal description of the current template virtual connection of the same associated pairs with the same type of input virtual description in to-be-designed equipment, checking the matching condition of each template virtual connection, and optimizing and rapidly searching the target associated pairs with the maximum matching number and the virtual connection thereof. According to the method disclosed in the invention, technical problem that the conventional virtual terminal design method is high in workload, low in efficiency and easy to cause errors and does not fully utilize the existing SCD design achievement is solved, the auxiliary automatic design of the virtual terminals of the intelligent substations is realized, the workload is greatly decreased, the intelligence, correctness and working efficiency are improved, and the reusability of the virtual terminal design achievement in the existing SCD is improved.

Description

technical field [0001] The invention relates to the field of design and debugging of intelligent substations, in particular to a fast search method for target association pairs aimed at multiple SCDs. Background technique [0002] At present, domestic design institutes use virtual terminal tables to describe the virtual terminal connections between devices in smart substations, and to design virtual connections for each device. At present, the virtual connection design of each device mainly adopts a manual method, that is, the designer first starts with the device virtual terminal source list given by the manufacturer, and manually copies and pastes to form a virtual connection receiving device, sending device, and input virtual terminal description , Input virtual terminal references, output virtual terminal descriptions, output virtual terminal references of each part of the text information, this method is not intelligent, the work is cumbersome, and it is easy to paste m...
