Description

Technical Field

[0001] This disclosure belongs to the field of power facility case management technology, and in particular relates to a power facility case management and application system and method. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] The inventors discovered that in recent years, the number of power facilities (such as synchronous condensers) deployed in various regions has been increasing. Due to the wide geographical distribution of these power facilities, the statistics on potential hazards, defects, or failures of these facilities are not comprehensive enough, making it impossible to effectively utilize some local cases. At the same time, due to the lack of a global case management system, the cases at each site are often limited to the use of that site itself and cannot be used as a reference for other similar sites. It is urgent to carry out work to reasonably and effectively collect all such equipment cases, analyze the cases, and use the case database to assist in on-site operation analysis. Summary of the Invention

[0004] To address the aforementioned issues, this disclosure provides a power facility case management and application system and method. The system enables the acquisition of power facility cases from different regions, ensuring comprehensive case acquisition and significantly increasing the probability of power facility operation and maintenance personnel accessing prior experience in the event of a fault. Furthermore, by classifying cases into ordinary and classic cases, and combining case-related countermeasures and standard quantity filtering to identify avoidable cases, the efficiency and accuracy of case selection for teaching purposes are effectively improved, thereby enhancing the teaching quality for power facility operation and maintenance personnel.

[0005] According to a first aspect of the embodiments of this disclosure, a power facility case management and application system is provided, comprising:

[0006] The case upload unit is configured to provide a case upload interface for management personnel at various power facility substations and management centers, as well as for the hidden danger, defect, and fault management subsystem, and to store the uploaded case information. The cases include three categories: hidden dangers, defects, and faults. The case information includes the case name, the site to which it belongs, the generating unit to which it belongs, the case description, the cause analysis, the corrective measures, and the systems, equipment, and components involved in the case. The systems, equipment, and components are components of the power facility.

[0007] The case analysis unit is configured to, for imported cases, select relevant countermeasures and standards from a pre-built countermeasure library and standard library based on the system, device and component to which the case belongs, and associate them; at the same time, it classifies cases into typical cases and ordinary cases based on case characteristics, wherein the case characteristics include, but are not limited to, the representativeness of the current case, the number of photos collected and the number of sites involved.

[0008] The case display unit is configured to graphically display the distribution of cases in various systems, devices or components, as well as typical cases. Each case is associated with a 3D model of its corresponding device and component. When any case is viewed, the 3D model will display the device involved in the case and highlight the specific component.

[0009] Furthermore, the construction of the countermeasures library and standard library specifically involves: pre-acquiring countermeasures and standards related to power facilities, and associating the acquired countermeasures and standards with the systems, equipment, and components in the power facility ledger.

[0010] Furthermore, the potential hazard refers to an abnormal state of equipment that has a certain probability of causing equipment defects or malfunctions; the defect refers to an abnormal operating state already exhibited by the equipment; and the malfunction includes, but is not limited to, a shutdown malfunction.

[0011] Furthermore, the case upload includes automatic import, manual import and remote import. The automatic import is when the case management system is associated with other hidden danger, defect and fault management subsystems. When the hidden danger, defect and fault management subsystem completes the solution formulation and verification for any hidden danger, defect or fault, it uploads the hidden danger, defect or fault and its management information as a case to the case management system.

[0012] or,

[0013] The manual import refers to the management center administrators manually creating cases, filling in the case information, and then saving.

[0014] or,

[0015] The remote import refers to each power facility substation remotely accessing the case management system, whereby the administrators of each power facility substation create new cases.

[0016] Furthermore, the case upload unit also provides a template import module. During manual or remote import, the case uploader can download the import template in advance, fill in the case information according to the template, and then upload the case by importing the template. The import template format includes, but is not limited to, Excel or XML format.

[0017] Furthermore, the step of selecting case-related countermeasures and standards from the pre-built countermeasures library and standard library for association specifically involves the case analysis unit obtaining relevant countermeasures and standards from the countermeasures library and standard library based on the system, equipment, and components to which the current case belongs, and displaying them in the editable interface. Administrators can select case-related countermeasures and standards from the editable interface to achieve the association between the case and its relevant countermeasures and standards.

[0018] Furthermore, for the countermeasures and standards associated with the case, managers can extract keywords from the countermeasures and standards as markers for the current case for subsequent case searches.

[0019] Furthermore, the case analysis unit is also configured to calculate the effective number N of cases based on the number of countermeasures and standards associated with each case.

[0020] N = Y * 1

[0021] Where N is the number of valid cases, and Y is the validity coefficient of the case. When a case has associated countermeasures or standards, it indicates that the case or similar cases have occurred before. Strictly adhering to the countermeasures or standards can prevent the current case from occurring. When calculating the number of valid cases, the validity coefficient of the case is less than 1. The validity coefficient is specifically calculated using the following formula:

[0022] Y = (a) n

[0023] Where a is the weighting factor, n is the number of countermeasures and standards associated with the case, and a takes a value greater than 0 and less than 1.

[0024] Furthermore, the case information uploaded by each power facility substation must be reviewed by the management personnel of the management center before being saved and stored in the database.

[0025] According to a second aspect of the present disclosure, a method for managing and applying power facility cases is provided, which is based on the above-described power facility case management and application system, including:

[0026] Management personnel at each power facility substation and management center, as well as the hidden danger, defect, and fault management subsystem, upload case studies and store the uploaded case information. The cases include three categories: hidden dangers, defects, and faults. The case information includes the case name, the site to which it belongs, the generating unit to which it belongs, the case description, the cause analysis, the handling measures, and the systems, equipment, and components involved in the case. The systems, equipment, and components are the components of the power facilities.

[0027] For imported cases, based on the system, equipment, and components to which the case belongs, relevant countermeasures and standards are selected from the pre-built countermeasure library and standard library for association; at the same time, cases are divided into typical cases and ordinary cases based on case characteristics, wherein the case characteristics include, but are not limited to, the number of real-scene photos of the current case and the number of sites involved in the case;

[0028] The system graphically displays the distribution of cases in various systems, devices, or components, as well as typical cases. Each case is associated with a 3D model of its corresponding device and component. When you click to view any case, the 3D model will display the device involved in that case and highlight the specific component.

[0029] Compared with the prior art, the beneficial effects of this disclosure are:

[0030] (1) This disclosure provides a power facility case management and application system and method. The solution realizes the acquisition of power facility cases in different regions through the case management and application system, ensuring the comprehensiveness of case acquisition. When a fault occurs, it greatly increases the probability that power facility operation and maintenance personnel can obtain the experience of predecessors. At the same time, by dividing the cases into ordinary cases and classic cases, and combining the number of case-related countermeasures and standards to screen out avoidable cases, the efficiency and accuracy of case selection suitable for teaching are effectively improved, and the teaching quality of power facility operation and maintenance personnel is improved.

[0031] (2) The solution described in this disclosure marks each case by associating it with relevant countermeasures and standards and providing keywords for countermeasures and standards, which can effectively improve the query efficiency when operation and maintenance personnel query relevant cases.

[0032] Advantages of this disclosure in additional aspects will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this disclosure. Attached Figure Description

[0039] The present disclosure will be further described below with reference to the accompanying drawings and embodiments.

[0040] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0041] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0042] Where there is no conflict, the embodiments and features described herein can be combined with each other.

[0043] Terminology Explanation:

[0044] Case studies include three categories: hidden dangers, defects, and malfunctions. Hidden dangers refer to abnormal equipment states that may cause equipment defects or malfunctions. Defects refer to abnormal operating states that the equipment has already exhibited. Malfunctions refer to tripping malfunctions (other malfunctions may also be introduced according to actual needs).

[0045] Case representativeness: This indicates the teaching value of the current case, and is mainly determined through expert evaluation.

[0046] Example 1:

[0047] The purpose of this embodiment is to provide a power facility case management and application system.

[0048] A power facility case management and application system, comprising:

[0049] The case upload unit is configured to provide a case upload interface for management personnel at various power facility substations and management centers, as well as for the hidden danger, defect, and fault management subsystem, and to store the uploaded case information. The cases include three categories: hidden dangers, defects, and faults. The case information includes the case name, the site to which it belongs, the generating unit to which it belongs, the case description, the cause analysis, the corrective measures, and the systems, equipment, and components involved in the case. The systems, equipment, and components are components of the power facility.

[0050] The case analysis unit is configured to, for imported cases, select relevant countermeasures and standards from a pre-built countermeasure library and standard library based on the system, device and component to which the case belongs, and associate them; at the same time, it classifies cases into typical cases and ordinary cases based on case characteristics, wherein the case characteristics include, but are not limited to, the representativeness of the current case, the number of photos collected and the number of sites involved.

[0051] The case display unit is configured to graphically display the distribution of cases in various systems, devices or components, as well as typical cases. Each case is associated with a 3D model of its corresponding device and component. When any case is viewed, the 3D model will display the device involved in the case and highlight the specific component.

[0052] Furthermore, the construction of the countermeasures library and standard library specifically involves: acquiring countermeasures and standards related to power facilities in advance, and associating the acquired countermeasures and standards with the systems, equipment and components in the equipment ledger.

[0053] Furthermore, the potential hazard refers to an abnormal state of equipment that has a certain probability of causing equipment defects or malfunctions; the defect refers to an abnormal operating state already exhibited by the equipment; and the malfunction includes, but is not limited to, a shutdown malfunction.

[0054] Furthermore, the case upload includes automatic import, manual import, and remote import, specifically:

[0055] The automatic import refers to the association between the case management system and other hidden danger, defect and fault management subsystems. When the hidden danger, defect and fault management subsystem completes the solution formulation and verification for any hidden danger, defect or fault, it uploads the hidden danger, defect or fault and its management information as a case to the case management system.

[0056] The manual import refers to administrators in the management center manually creating cases, filling in the case information, and saving; specifically, the manual import refers to associated personnel creating cases themselves. After clicking "Add Case," a pop-up window will appear as shown below. Figure 1The fault case maintenance pop-up window shows the case name, the site and the unit to which it belongs, which should be filled in according to the actual situation. Clicking the add button after the relevant system, equipment and component can associate the case with the relevant system, equipment and component. After filling in the time description, cause analysis and handling measures according to the actual situation, save it into the case library.

[0057] The remote import process involves each power facility substation remotely accessing the case management system, whereby administrators at each substation create new cases. The remote import (i.e., the case information uploaded by each power facility substation) must be reviewed and approved by the management center administrators before being saved to the database.

[0058] Furthermore, the case upload unit also provides a template import module. During manual or remote import, the case uploader can download the import template in advance, fill in the case information according to the template, and then upload the case by importing the template. The import template format includes, but is not limited to, Excel or XML format.

[0059] Furthermore, for cases in the case library, the case management and application system provides the following display methods:

[0060] like Figure 2 As shown, the "Add Fault" option on the left is the entry point for manually entering cases. "Download Template" and "Import Case" allow you to fill in case information based on the pre-set templates. Keywords, site, unit, and case source can be used to search for target cases. Case types are divided into typical cases and ordinary cases. If a typical case is selected, the case will be set as typical. Typical cases can be displayed in detail in the application system for teaching purposes.

[0061] Furthermore, the step of selecting case-related countermeasures and standards from the pre-built countermeasures library and standard library for association specifically involves the case analysis unit obtaining relevant countermeasures and standards from the countermeasures library and standard library based on the system, equipment, and components to which the current case belongs, and displaying them in the editable interface. Administrators can select case-related countermeasures and standards from the editable interface to achieve the association between the case and its relevant countermeasures and standards.

[0062] Furthermore, for the countermeasures and standards associated with the case, managers can extract keywords from the countermeasures and standards as markers for the current case for subsequent case searches.

[0063] Furthermore, the case analysis unit is also configured to calculate the effective number N of cases based on the number of countermeasures and standards associated with each case.

[0064] N = Y * 1

[0065] Where N is the number of valid cases, and Y is the validity coefficient of the case. When a case has associated countermeasures or standards, it indicates that the case or similar cases have occurred before. Strictly adhering to the countermeasures or standards can prevent the current case from occurring. When calculating the number of valid cases, the validity coefficient of the case is less than 1. The validity coefficient is specifically calculated using the following formula:

[0066] Y = (a) n

[0067] Where a is the weighting factor, n is the number of countermeasures and standards associated with the case, and a takes a value greater than 0 and less than 1.

[0068] The above features have the following beneficial effects: Since there are a large number of cases in the case library, how to select suitable cases for teaching is a difficult problem in existing solutions. This embodiment, based on dividing cases into ordinary cases and classic cases, adopts the above strategy to effectively eliminate cases that are associated with a large number of countermeasures or standards (those skilled in the art should know that the more countermeasures and standards associated with a case, the more it proves that the case can be avoided by strictly implementing the countermeasures or standards. Therefore, such cases have no teaching value and their effectiveness coefficient is low). Based on the above-mentioned effectiveness coefficient, the selection accuracy and efficiency of the most suitable teaching cases can be effectively improved.

[0069] Furthermore, the case study presentation section will employ the following presentation strategy:

[0070] like Figure 3 As shown, the components with the most frequent cases are displayed on the large display screen, with the components listed first in terms of the number of cases.

[0071] and,

[0072] like Figure 4 As shown, the size of the case library is displayed, where the total number of cases is the algebraic sum of the number of cases;

[0073] and,

[0074] Three-dimensional models of different devices are pre-built, and three-dimensional models of power facilities are embedded in the case management and application system. When any case is clicked, the three-dimensional model will display the components involved in the case, which facilitates the understanding of the case.

[0075] and,

[0076] like Figure 5 As shown, typical cases are highlighted. For cases identified as typical cases in the case management system, the application system displays the detailed content of the case and dynamically displays the detailed information of different typical cases.

[0077] Example 2:

[0078] The purpose of this embodiment is to provide a method for the management and application of power facility cases.

[0079] A method for managing and applying power facility cases, based on the aforementioned power facility case management and application system, includes:

[0080] Management personnel at each power facility substation and management center, as well as the hidden danger, defect, and fault management subsystem, upload case studies and store the uploaded case information. These cases include three categories: hidden dangers, defects, and faults. The case information includes the case name, the site it pertains to, the generating unit it pertains to, the case description, the cause analysis, the corrective measures, and the systems, equipment, and components involved in the case. These systems, equipment, and components are integral parts of the power facility.

[0081] For imported cases, based on the system, equipment, and components to which the case belongs, relevant countermeasures and standards are selected from the pre-built countermeasure library and standard library for association; at the same time, cases are divided into typical cases and ordinary cases based on case characteristics, wherein the case characteristics include, but are not limited to, the number of real-scene photos of the current case and the number of sites involved in the case;

[0082] The system graphically displays the distribution of cases in various systems, devices, or components, as well as typical cases. Each case is associated with a 3D model of its corresponding device and component. When you click to view any case, the 3D model will display the device involved in that case and highlight the specific component.

[0083] The power facility case management and application system and method provided in the above embodiments can be implemented and has broad application prospects.

[0084] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
