Embodiment Construction

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] figure 1 It is a flow chart of the intelligent substation SCD file parallel parsing method of the present invention, such as figure 1 shown, including steps:

[0020] Step S101: Import the SCD file into the memory, adopt a master-slave mechanism, the main thread extracts the structure of the SCD file, and the slave thread parses the name and nature of the tag. There is a serial relationship between the main thread and the slave thread; a parallel relationship between the main thread and the main thread, and between the slave thread and the slave thread.

[0021] Step S102: figure 2 It is the structural diagram of the SCD file, and the ellipsis in the figure is the label contained under the secondary label of the SCD file. Corresponding to the structure of the SCD file, five main threads of Header, Substation, Communication, IED ...

Abstract

The invention relates to a parallel parsing method for SCD files of an intelligent substation. A master-slave parsing mechanism is adopted, the main thread extracts the structure of the SCD file, and the slave threads parse the names and properties of labels. The main thread and the slave thread are in a serial relationship; the main thread and the main thread, and the slave thread and the slave thread are in a parallel relationship. Start five types of main threads in parallel according to the SCD file structure, mark the first-level label position of the SCD file, and save the label position information; count the number of first-level label positions, and start the same number of slave threads to analyze the first-level label and the labels it contains The name and nature of the analysis result of each slave thread is stored in a tree structure, and a type subtree is established, and each subtree is integrated into a complete main tree according to the SCD file structure; the parsing process uses a parallel hash algorithm to realize the tree structure Quick Search. The invention adopts the parallel multi-thread technology to greatly reduce the analysis time of the SCD file and improve the result query efficiency.

Description

technical field [0001] The invention belongs to the field of electric power intelligent substations, and relates to a parallel analysis method for SCD files of intelligent substations. Background technique [0002] The SCD (Substation Configuration Description) file is called the substation configuration file. The SCD file is a smart substation configuration file described by the SCL language, which fully describes the relationship between the primary intelligent equipment of the smart substation and the secondary network equipment, and the data model and control model related to equipment functions and communication services. Therefore, the SCD file is the most important document in the construction and maintenance process of the smart substation, and it is the textualized design drawing of the smart substation. [0003] Due to the construction and maintenance of smart substations, it is often necessary to view and modify SCD files. SCD file parsing is a process that take...
