In addition, it can be understood that the terms defined in the commonly used dictionary should be understood to have a meaning consistent with the context of their related fields, and should not be understood as idealized or overly formal meanings.

[0024] Intelligent substations are divided into forms such as 3 / 2 wiring, double busbar wiring, and single busbar sectionalization according to voltage levels. Primary equipment includes transformers, lines, circuit breakers, instrument transformers, etc. Secondary equipment includes merging units, intelligent terminals, and relay protection equipment. The substation system configuration description file, abbreviated as the SCD (Substation Configuration Description) file, mainly describes the loop association relationship between secondary equipment according to the main wiring relationship of primary equipment in the substation, realizes the correct acquisition of SV signals such as voltage and current and switch position GOOSE messages by secondary equipment, and when a fault occurs, the relay protection equipment outputs switch quantity GOOSE message signals such as opening and closing to the specified intelligent terminal to ensure the rapid isolation of faulty equipment. The correctness of the process layer configuration file of the SCD file directly affects the correctness of the protection device action and the safety of the power grid.

[0025] Figure 1 An exemplary flowchart of a method for configuring a substation system configuration description file according to an embodiment of the present invention is shown.

[0026] As Figure 1 shown, the method includes:

[0027] Step S101: Obtain the SSD file.

[0028] The SSD file is an abbreviation for the system specification description file, which may include descriptions of intelligent substations divided into forms such as 3 / 2 wiring, double busbar wiring, and single busbar sectionalization according to voltage levels, descriptions of primary equipment including transformers, lines, circuit breakers, and instrument transformers, and descriptions of secondary equipment including merging units, intelligent terminals, and relay protection.

[0029] Step S102: Establish a list of primary equipment in the substation according to the SSD file by interval.

[0030] Further, step S102 includes:

[0031] Parse the SSD file, and according to the descriptions of each VoltageLevel under Substation, establish a list of substation voltage partition by voltage level;

[0032] According to the descriptions of each Bay under VoltageLevel, establish a list of bay partition under different voltage levels of the substation by bay;

[0033] According to the descriptions of each level of Equipment under Bay, establish a list of primary equipment of the substation.

[0034] Further, according to the descriptions of each level of Equipment under Bay, establishing a list of primary equipment of the substation includes:

[0035] According to the descriptions of each level of Equipment under Bay, establish a list of primary equipment of the substation by automatically segmenting words level by level.

[0036] According to each level of Equipment under Bay, including PowerTransformer, TransformerWinding, ConductingEquipment and Function, describe by equipment, function, etc., and establish a list of primary equipment of the substation by automatically segmenting words level by level, including CBR circuit breakers, CTR / VTR instrument transformers, etc.

[0037] Step S103: According to the list of primary equipment of the substation, establish a list of relationships between each secondary equipment IED and the corresponding primary equipment under the same bay.

[0038] The same bay refers to the bay that is the same as the one for establishing the list of primary equipment of the substation. IED is the abbreviation of Intelligent Electronic Device.

[0039] Further, step S103 includes:

[0040] Extract each LNode under each level of Equipment from the list of primary equipment of the substation according to the description of iedName equipment name, and establish a list of relationships between each secondary equipment IED and the corresponding primary equipment under the same bay through keyword screening.

[0041] The list of relationships between each secondary equipment IED and the corresponding primary equipment under the same bay may include the list of relationships between merging units, intelligent terminals, relay protections, etc. and circuit breakers, instrument transformers.

[0042] Based on the hierarchical Equipment device and function keyword library of the SCD file in the intelligent substation, screen the secondary device LNode model data under the Bay interval to be analyzed, eliminate the interference of invalid data, and form a one-to-one and professional associated list of secondary device iedName. Compared with the primary device structured topology relationship formed by automatic word segmentation step by step, keyword screening further describes the association relationship between the primary and secondary devices, eliminates the interference of words irrelevant to the association relationship and secondary device keywords, can speed up the secondary device association analysis, and improve the association accuracy.

[0043] Step S104: According to the relationship list between each secondary device IED and the corresponding primary device under the same interval, establish an associated relationship list of each interacting secondary device IED under the same interval.

[0044] Furthermore, step S104 includes:

[0045] According to the relationship list between each secondary device IED and the corresponding primary device under the same interval, establish an associated relationship list of each interacting secondary device IED under the same interval through auxiliary analysis.

[0046] By using artificial intelligence data analysis methods such as the typical interval secondary device association analysis method, automatically search for the secondary devices associated with each type of interval, sort according to the relevance, and find the most relevant secondary device relationship list, which can accurately support the automatic association of the secondary devices to be analyzed and make full use of historical experience to support the rapid identification and handling of the relationship between secondary devices.

[0047] Step S105: According to the associated relationship list of each interacting secondary device IED under the same interval and the interval information, establish the virtual terminal type connection relationship and interval serial number of each associated secondary device IED under the same interval.

[0048] Furthermore, step S105 includes:

[0049] According to the secondary device types in the associated relationship list of each interacting secondary device IED under the same interval, through association analysis, determine the virtual terminal type connection relationship of each associated secondary device IED under the same interval, and establish the virtual terminal interval serial number of each associated secondary device IED according to the interval information in the substation primary device list.

[0050] Step S106: Configure the virtual terminal connection of each secondary device IED according to the virtual terminal type connection relationship and interval serial number of each associated secondary device IED under the same interval.

[0051] According to the virtual terminal type connection relationship and interval serial number of each associated secondary device IED under the same interval, realize the automatic configuration of SCD according to the virtual terminal template library, and configure the virtual terminal connection of each secondary device IED.

[0052] By using artificial intelligence data analysis methods such as the secondary device type correlation analysis method, automatically analyze the list of secondary device relationships, determine the virtual terminal types and bay sequence numbers of related secondary devices, which can accurately support the automatic association of the virtual terminals of the secondary devices to be analyzed, and make full use of historical experience to support the rapid identification and disposal of the connections of secondary device virtual terminals.

[0053] The configuration methods of the substation system configuration description files provided by the various embodiments of the present invention have the following advantages:

[0054] (1) Improve the efficiency of the configuration file. The main wiring of primary equipment in intelligent substations is diverse, the number of secondary devices is large, the loop connections between secondary devices are complex and diverse, and at the same time, the SCD file is becoming more and more huge, resulting in increasing difficulty in file parsing and analysis, and higher requirements for the capabilities of relevant professional and technical personnel, which brings a great deal of workload to the work of substation design, commissioning, operation and maintenance, and management. The present invention aims to provide an SCD configuration method based on SSD association, make full use of the existing SSD file information and the definition of secondary device virtual terminals, and adopt various algorithms such as hierarchical automatic word segmentation and correlation analysis to assist in comparative analysis, so as to achieve rapid automatic configuration of the process layer connection of the SCD file and improve the maintenance efficiency of the SCD file in intelligent substations.

[0055] (2) Improve the reliability of the configuration file. During the design, commissioning, or renovation and expansion of intelligent substations based on IEC61850, the functions of secondary devices such as data acquisition and opening / closing commands rely heavily on the process layer configuration of the SCD file, and the accuracy of its configuration directly affects the reliable operation of secondary devices. Manual configuration of the SCD file has a large workload and inconsistent configuration, and there are situations such as missing configuration and incorrect configuration. Under the existing technical means, the debugging and operation and maintenance of the SCD file are difficult. The present invention provides an SCD configuration method and system based on SSD association, which solves the problems of a large number of types of secondary devices, diverse data characteristics, complex connection relationships, and high requirements for the experience and capabilities of SCD configuration personnel in existing intelligent substations. Compared with similar technologies, it makes full use of existing file data and model information, has a high degree of automation, an advanced solution, and is easy to implement, improving the reliability of the configuration file.
