Abstract

The invention discloses an intelligent substation SCD document rapid analysis method. The intelligent substation SCD document rapid analysis method comprises the steps that a SCD document is loaded, node data of the SCD document adopt a deep-analysis and shallow-copy method, and a tree structure object is established; the data extraction is conducted according to the tree structure object, and a global hash table is established; all node data in the SCD document are searched rapidly according to the mapping relation of the global hash table. According to the intelligent substation SCD document rapid analysis method, the memory overhead is reduced, the time consumption is lowered, and the searching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent substation automation, in particular to a method for quickly analyzing SCD files of an intelligent substation. Background technique [0002] In a smart substation, the substation configuration description file (substation configuration description, SCD) describes the protection settings, data description, data type, communication parameters, control block parameters and The interconnection relationship between devices, especially information such as SMV and GOOSE data types, descriptions, and short addresses. In the process of design, commissioning, operation and maintenance, renovation and expansion of smart substations, it is necessary to repeatedly modify the content of the SCD file, so it is necessary to repeatedly open the SCD file to analyze and view the data information. At present, the main work of SCD analysis in smart substation is to quickly extract the data information of each IED...
