Description

Technical Field

[0001] The present invention belongs to the technical field of automatic generation of secondary safety measures for intelligent substations, and in particular to a method for establishing an information supplement model and extracting information from secondary safety measures tickets for intelligent substations. Background Art

[0002] At present, the research on the secondary main equipment of smart substations has been basically completed. The "nine unified" tests have been carried out for relay protection, and the "four unified" tests have been carried out for automation equipment. By carrying out standardized tests, a relatively unified secondary equipment operating environment has been established, which facilitates the debugging and operation and maintenance of the on-site secondary system and lays a certain foundation for the implementation of intelligent operation and maintenance.

[0003] Major domestic equipment manufacturers are actively conducting research on intelligent O&M for secondary equipment, exemplified by online monitoring and visual diagnostic systems for secondary equipment. These systems primarily visualize the physical network, secondary logical links, and operating status of protection equipment throughout the entire station, as well as intelligently diagnose defects, automatically generate secondary safety measures, and issue early warnings. The system's secondary physical circuit mapping, physical circuit fault location, and automatic generation of secondary safety measures all require the support of a substation secondary model.

[0004] Currently, safety precautions are primarily written manually, resulting in low efficiency and prone to errors. Most applications for automatically generating secondary safety precautions can basically generate safety precautions related to soft pressure plates, but lack a basic data source for outputting other information required for the actual secondary safety precautions, such as terminal blocks, hard pressure plates, and circuit breakers.

[0005] In order to solve the above-mentioned technical barriers in the current operation and maintenance of smart substations, in the past two years, various domestic units have proposed SPCD files for the real optical fiber circuits of smart substations, and gradually formed two relatively independent files for virtual and real circuits. Together with the SCD file, a secondary optical fiber circuit file covering the substation has been initially formed. The secondary panoramic circuit file can already meet the needs of secondary physical circuit mapping, physical circuit fault location, and optical fiber circuit smart labeling. However, it still does not provide sufficient support for the automatic generation of secondary safety measures, because the SCD and SPCD files lack the component information of the safety measure calculation panel cabinet equipment, such as circuit breakers, hard pressure plates, terminal block information, etc., which is not conducive to the complete output of secondary safety measure information.

[0006] Since the research on SPCD files has been preliminarily completed and national standards and enterprise standards have been issued, it is not convenient to conduct expanded research on SPCD files. Therefore, how to continue to perform supplementary modeling (referred to as supplementary models) and information extraction for other parts of the secondary system is a technical problem that needs to be solved urgently by technical personnel in this field. Summary of the Invention

[0007] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a method for establishing a supplementary model for secondary security tickets of intelligent substations and extracting information, which can solve the problem of all data modeling of secondary security tickets and effectively support the automatic analysis and generation of secondary security tickets.

[0008] The present invention solves the technical problem by adopting the following technical solutions:

[0075] The specific method of step 3 is:

[0076] Analyze the differentiated content between the secondary security measures supplement model and SPCD;

[0077] Obtain the room information, panel information, and equipment information from the SPCD file and extract them into the secondary safety measures supplementary model, thereby completing and extracting the physical information of the smart substation required for the secondary safety measures ticket;

[0081] The present invention will be further described below by taking an example of a 220kV line protection fault elimination measure:

[0082] The safety measure is to adopt a double-mother and double-section busbar connection method for the 220kV primary main connection, and adopt the intelligent station line protection and fault elimination method of merged unit sampling and GOOSE tripping mode.

[0083] (1) Pre-deficiency measures

[0084] a. Exit the GOOSE trip output soft pressure plate, start failure output soft pressure plate, and reclosing output soft pressure plate within the line protection, and put the first set of line protection maintenance pressure plates in this interval into operation;

[0085] b. If necessary, disconnect the optical fiber from the line protection to the opposite side optical difference channel and the line protection backplane optical fiber.

[0086] (2) Transmission test safety measures

[0087] a. Exit the GOOSE start failure receiving soft pressure plate of the line protection interval in the corresponding 220kV first busbar protection;

[0088] b. Exit the GOOSE start-up failure of the line protection and send the soft pressure plate, and put the first set of line protection maintenance pressure plate in the interval into use;

[0089] c. Remove the first set of intelligent terminal exit hard pressure plates in the line interval and put in the intelligent terminal maintenance pressure plates;

[0090] This safety measure plan can be transmitted to the hard pressure plates at the exits of relevant intelligent terminals. If necessary, the equipment can be shut down once for a complete transmission test of the entire group.

[0091] In this embodiment, the differences between the secondary security supplement model and SPCD are further analyzed:

[0092] The SPCD file of the smart substation uses XML language to digitally construct the physical circuit of the entire substation, including the IPCD file information formed by all physical equipment in the station (including devices, optical distribution and switches, etc.), such as Figure 1 As shown in the figure, the IPCD file contains the board information (location information, usage information) and port information (port type, port number, port location, etc.) of the secondary physical equipment. At the same time, the SPCD file also includes a wealth of substation physical information such as small rooms, cabinets, equipment, physical loop connections, optical cable models and numbers, etc. Figure 2 shown.

[0093] According to the requirements of the State Grid Enterprise Standard Q / GDW11357 "Safety and Security Regulations for On-site Work of Relay Protection and Grid Safety Automatic Devices in Smart Substations", the cabinet information required for the secondary safety measure ticket is as follows: Figure 3 shown.

[0094] By parsing the SPCD file, the information that can be obtained is the small room information, panel cabinet information, and equipment information. Some content such as the panel cabinet hard pressure plate information, circuit breaker information, and loop terminal information are obviously missing. Therefore, it is necessary to use the secondary safety measure supplementary model to model it, thereby completing the physical information part of the smart substation required by the secondary safety measure ticket.

[0095] In this example, the differences between the secondary security supplement model and SCD are further analyzed:

[0096] The SCD file of the smart substation uses XML language to digitally construct the virtual circuit of the entire substation, including the connection relationship between the substation GOOSE and SV, as well as the model information of all secondary equipment, which is uploaded through MMS.

[0097] Secondary safety measures for smart substations require a full understanding of the soft pressure plate mechanism of secondary equipment and an accurate mapping of the relationship between the soft pressure plate and the virtual circuit in order to effectively and correctly activate and deactivate the soft pressure plate of secondary equipment. At the same time, the soft pressure plate of secondary equipment is divided into functional soft pressure plate and process layer soft pressure plate.

[0098] There are three types of process layer soft pressure plates: GOOSE sending soft pressure plates, GOOSE receiving soft pressure plates, and SV soft pressure plates. According to the State Grid 1396 specification, soft pressure plates only exist in station control layer equipment such as protection and measurement and control, and GOOSE receiving soft pressure plates only exist in the failure circuits of busbar differential and main transformer protection.

[0099] (1) When GOOSE sends the soft pressure plate to exit, the device does not send the corresponding protection command to the outside;

[0100] (2) When the GOOSE receiving soft pressure plate exits, this device does not perform logical processing on the corresponding GOOSE signal sent by other devices;

[0101] (3) When the SV soft pressure plate is withdrawn, the sampling value of the corresponding circuit of this device is not displayed and does not participate in the protection calculation.

[0102] According to the 1396 specification, the GOOSE sending soft pressure plate and the sending virtual terminal can be mapped by corresponding the ref reference name and the instance number. The GOOSE receiving soft pressure plate and the SV soft pressure plate can be manually specified through the software interface.

[0103] The functional soft pressure plate cannot be set in the above way. At the same time, the description of the functional soft pressure plate is often inconsistent between the description in the device and the description in the SCD. Therefore, it is also necessary to use secondary measures to supplement the model for modeling improvement.

[0104] like Figure 5 The figure shows an example of the results of the present invention.

[0105] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific embodiments. Any other embodiments derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
