Technical Field
[0002] This invention belongs to the field of railway electrification engineering training technology, specifically relating to a railway power supply professional training base system and method. Background Technology
[0003] With the development of railway electrification and intelligentization, higher demands are placed on the professional skills and practical abilities of power supply system operation and maintenance personnel. Existing railway vocational training facilities generally suffer from problems such as narrow professional coverage, low system integration, insufficient simulation of training environments, and a lack of emergency response drills, making it difficult to meet the comprehensive training needs of traction power supply systems across all specialties and scenarios. Furthermore, some vocational training bases have outdated facilities and limited equipment types, failing to cover the diverse power supply scenarios of modern railways, and the training content lags behind actual needs.
[0004] Existing railway vocational training bases suffer from the following problems: First, limited equipment and scenarios: Most bases are currently equipped only with small electrical equipment or simple models, unable to simulate a complete power supply system including traction substations, overhead contact lines, and electricity. Trainees lack practical experience with real power supply processes and complex operating conditions. Second, limited training content: Training focuses primarily on basic operation and maintenance, lacking practical training such as power supply fault diagnosis and emergency drills, making it difficult to effectively improve trainees' emergency response capabilities. Third, lack of intelligent monitoring and evaluation: Some bases lack training and assessment platforms, making it impossible to achieve real-time monitoring of equipment operation status and quantitative evaluation of trainees' operational processes, thus hindering precise control of training quality. Facilities generally suffer from narrow professional coverage, low system integration, and insufficient simulation of training environments, making it difficult to meet the comprehensive training needs of the traction power supply system across all specialties and scenarios.
[0005] To address this issue, there is an urgent need to build a professional vocational training base system that covers three areas: traction substation, overhead contact line, and power system, and has high simulation accuracy, high safety, and high operability, forming a comprehensive platform that integrates teaching demonstrations, practical training, simulation evaluation, and fault drills. Summary of the Invention
[0006] To overcome the shortcomings of existing technologies, this invention provides a railway power supply professional training base system and method. By building a comprehensive training platform that integrates traction substation, catenary, power supply, emergency support, intelligent monitoring and practical assessment, the practical skills and emergency response capabilities of railway power supply operation and maintenance personnel are comprehensively improved.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A vocational training base system for railway power supply includes a traction substation training module, an overhead contact line training module, an electric power training module, and a training and assessment module. The traction substation training module is based on the structure of the traction substation and simulates the complete operation process of the railway traction power supply system. The overhead contact line training module simulates the structure and operating status of the overhead contact line system in an electrified railway section; The power training module simulates the composition and operation of 10kV and 0.4kV power systems along the railway line; The practical training and assessment module serves as the intelligent control and management hub of the entire base system, integrating a teaching resource management system, a practical training process management system, a skills assessment and evaluation system, and a data analysis platform.
[0008] Furthermore, the traction substation training module is equipped with traction transformers, station transformers, high-voltage circuit breakers, disconnect switches, voltage transformers, current transformers, surge arresters, integrated automation simulation systems, AC / DC systems, grid switch monitoring systems, and auxiliary monitoring systems, arranged in a realistic or scalable manner.
[0009] Furthermore, the overhead contact line training module simulates the structure and operating status of the overhead contact line system in an electrified railway section. The module includes contact wire, droppers, catenary wire, positioning device, rigid crossbeam, phase insulator, section insulator, overhead contact line support, and overhead contact line disconnector, and is also equipped with a fault simulation unit.
[0010] Furthermore, the power training module simulates the structure and operation of 10kV and 0.4kV power systems along the railway line. The power training module includes power transformers, distribution cabinets, cable lines, grounding devices, lighting and power equipment, integrated automation systems, AC / DC systems, and cable fault simulation systems, and simulates the power distribution systems of stations, yards, and living areas.
[0011] Furthermore, the practical training and assessment module serves as the intelligent control and management hub of the entire base system, integrating a teaching resource management system, a practical training process management system, a skills assessment and evaluation system, and a data analysis platform.
[0012] A vocational training method for railway power supply professionals includes the following steps: Step 1: Assigning practical training project tasks; Step Two: Record the entire process of the student's operation; Step 3: Automatic scoring and result archiving.
[0013] Furthermore, step one specifically includes: When the system starts, trainees log in via facial recognition or work card authentication. The system automatically links their job attributes and historical training files. Based on a preset job competency matrix, the intelligent matching engine prioritizes pushing required practical training projects while dynamically inserting content to strengthen weaknesses. After the task is determined, the system assigns the corresponding VR simulation scene and physical simulation equipment, and pushes a structured electronic task book to the trainee's terminal, clarifying the operation objectives, safety regulations, and scoring standards.
[0014] Furthermore, step two specifically involves: Trainees' actions in the virtual environment are captured in real time by a multimodal sensor network: VR controller trajectories reflect the operation sequence, eye-tracking data monitors attention distribution, and sensors in the physical simulation device record the accuracy of parameter settings. The system performs millisecond-level risk assessments through a rule engine. When a violation of safety procedures is detected, the scene is immediately frozen and a three-level intervention mechanism is triggered: first, a red warning box is generated to cover the error point; then, a video of an accident case caused by the violation is played; finally, the trainee is required to re-demonstrate the correct procedure in the virtual environment. All operation data is filtered and denoised, and then encoded into structured JSON data packets by timestamp. Key operation nodes are compared in real time with a standard procedure library, and the difference value serves as the raw input for subsequent scoring.
[0015] Furthermore, step three specifically includes: After training, the system calls the pre-trained big data evaluation model to generate quantitative scores from four dimensions: operational standardization (examining the completeness of steps and compliance with safety red lines); processing efficiency (comparing standard time consumption, with points deducted proportionally if fault location timeout); theoretical application (evaluating the correctness of theoretical knowledge used in the operation); equipment loss statistics (statistics of simulated losses caused by virtual equipment misoperation); the evaluation results are used to generate a 3D capability radar chart and PDF report through a visualization engine; finally, the data packet is encrypted and written to the student's file database, while anomaly summaries are pushed to the teacher's terminal.
[0016] The beneficial effects of this invention are: 1) This invention constructs a full-element power supply training environment that closely resembles actual combat. The system configuration covers core equipment such as traction substations, catenary systems, and 10 / 0.4kV power distribution systems, simulating the operating status and typical working conditions of each link in the power supply of electrified railways. It meets the needs of power supply operation and maintenance training and multi-scenario fault emergency drills, and significantly improves trainees' adaptability to the actual working environment and emergency response level. 2) This invention integrates teaching, training and assessment, and constructs a closed-loop vocational training system; it is equipped with standardized assessment devices and intelligent evaluation systems to realize an integrated training process of "teaching-training-examination-evaluation", comprehensively improve the trainees' comprehensive abilities and job competence, and meet the training needs of modern railways for high-quality power supply personnel.

Detailed Implementation
[0018] The present invention will now be described in detail with reference to specific embodiments.
[0019] This invention provides a system configuration scheme for a railway power supply vocational training base targeting three professional directions: traction substation, catenary, and power. It is applicable to vocational education scenarios such as practical training, skills training, and emergency drills for railway power supply equipment.
[0020] like Figure 1 As shown, the railway power supply professional vocational training base system of the present invention includes a traction substation training module, a catenary training module, a power training module, and a training teaching and assessment module; like Figure 2 As shown, the traction substation training module is based on the structure of a traction substation and simulates the complete operation process of a railway traction power supply system. The traction substation training module is equipped with key equipment such as traction transformers, station transformers, high-voltage circuit breakers, disconnecting switches, voltage transformers, current transformers, surge arresters, integrated automation simulation systems, AC / DC systems, grid switch monitoring systems, and auxiliary monitoring systems. It adopts a realistic scale or a scaled-down layout to achieve teaching objectives such as wiring training for AC 27.5kV systems, switching operation drills, protection setting and testing operations, fault simulation, and emergency handling.
[0021] The integrated automation simulation system sets up protection and control devices for traction substations, AT stations, and section substations according to AT or direct power supply methods, and realizes remote control of indoor and outdoor high-voltage equipment and contact network disconnect switches, meeting the needs of employees for secondary measurement and control circuit knowledge and fault finding training.
[0022] like Figure 3As shown, the overhead contact line training module simulates the structure and operation of the overhead contact line system in an electrified railway section. The module includes components such as contact wire, droppers, catenary wire, positioning devices, rigid crossbeams, phase insulators, section insulators, overhead contact line supports, and overhead contact line disconnect switches. It also includes a fault simulation unit to simulate typical fault scenarios such as wire breakage, arcing, and tripping, for emergency response training and accident drills. This module supports training operations using various power supply methods (such as AT power supply and direct power supply) and overhead contact line installation methods, enabling skills training in overhead contact line installation, maintenance, adjustment, inspection, and diagnosis.
[0023] like Figure 4 As shown, the power training module simulates the structure and operation of 10kV and 0.4kV power systems along railway lines. The module includes facilities such as power transformers, distribution cabinets, cable lines, grounding devices, lighting and power equipment, integrated automation systems, AC / DC systems, and cable fault simulation systems, and simulates the power distribution systems of stations, yards, and living areas. The module allows for hands-on training in power distribution system operation and maintenance, line fault diagnosis, load regulation and management, and power quality testing, enhancing trainees' problem-solving abilities in actual power supply assurance work.
[0024] The practical training and assessment module serves as the intelligent control and management hub of the entire base system, integrating a teaching resource management system, a practical training process management system, a skills assessment and evaluation system, and a data analysis platform. This module supports multi-dimensional assessment methods, including standardized work process evaluation, emergency response capability testing, and knowledge quizzes, forming a scientific, fair, and traceable evaluation system for practical training outcomes. The platform also features remote teaching and practical training simulation capabilities, providing technical support for employee continuing education, emergency retraining, and refresher training.
[0025] This invention also provides a method for vocational training in railway power supply, such as... Figure 5 As shown, it includes the following steps: Step 1: Assigning practical training project tasks, specifically: When the system starts, trainees log in via facial recognition or work card authentication. The system automatically associates their job attributes (such as substation maintenance worker, overhead contact line maintenance worker) and historical training files. Based on the preset job competency matrix, the intelligent matching engine prioritizes pushing required practical training projects (such as "27.5kV GIS equipment fault isolation"), while dynamically inserting content to strengthen weaknesses. For example, if a trainee's past records show that the frequency of "non-standard voltage testing operation" exceeds the standard, the high voltage voltage testing special training module will be automatically inserted. The task matching process uses a weighted decision algorithm, with job requirements accounting for 60% and personal skill deficiencies accounting for 40%, ensuring that the training content is both in line with the job outline and personalized. Once the task is determined, the system assigns the corresponding VR simulation scene and physical simulation equipment (such as an electroscope force feedback device), and pushes a structured electronic task book to the trainee's terminal, clarifying the operation objectives, safety regulations and scoring criteria.
[0026] Step Two: Record the entire student's operation process, specifically as follows: The trainees' actions in the virtual environment are captured in real time by a multimodal sensor network: the VR controller trajectory reflects the operation sequence (such as whether to check the power before connecting the ground wire), eye-tracking data monitors the distribution of attention, and the sensors of the physical simulation equipment (such as current transformers) record the accuracy of parameter settings. The system uses a rule engine to make millisecond-level risk assessments. When it detects a violation of safety procedures (such as operating a disconnect switch without wearing insulated gloves), it immediately freezes the scene and triggers a three-level intervention mechanism: first, it generates a red warning box to cover the error point; then, it plays a video of an accident case caused by the violation (such as real footage of an electric arc burn); and finally, it requires trainees to re-demonstrate the correct procedure in the virtual environment. After all operational data is filtered and denoised, it is encoded into structured JSON data packets by timestamp. Key operational nodes (such as circuit breaker tripping time and protection plate activation / deactivation status) are compared with the standard process library in real time, and the difference value is used as the raw input for subsequent scoring.
[0027] Step 3: Automatic scoring and result archiving, specifically: After training, the system calls the pre-trained big data evaluation model to generate quantitative scores from four dimensions: Operational Standardization (40%) focuses on the completeness of steps and compliance with safety red lines. For example, insufficient voltage testing will result in a direct deduction of 20 points; Processing Efficiency (30%) compares the time taken to the standard, and deducts points proportionally if fault location times out; Theoretical Application (20%) evaluates the correctness of theoretical knowledge used in the operation. For example, incorrect reference to relay protection setting formulas will be marked as a theoretical defect; Equipment Loss (10%) calculates the simulated losses caused by virtual equipment misoperation (such as a short circuit causing a "virtual surge arrester explosion"). The evaluation results are used to generate a 3D capability radar chart and a PDF report through a visualization engine, which includes screenshots of erroneous operation frames, a comparison table with the standard process, and improvement suggestions. Finally, the data packet is encrypted and written to the student file database, and at the same time, an anomaly summary is pushed to the teacher's terminal—for example, when the error rate of the "mechanical interlocking of the isolating switch" step in the same teaching class exceeds the threshold, a collective retraining suggestion is triggered.
