Technical Field
[0001] The invention belongs to the field of photovoltaic power station training devices, and specifically refers to a multifunctional simulation training device for photovoltaic power stations. Background Art
[0002] With the rapid development of the new energy industry, especially the progress of the solar photovoltaic industry, the demand for the construction and operation and maintenance of photovoltaic power stations is increasing. In order to ensure the safe and stable operation of the power station, the professional skills required of power station operators are getting higher and higher. Traditional theoretical learning is difficult to meet the needs of actual operation. The operating environment of the real power station is complex and changeable, and there are certain safety risks. Therefore, it is imperative to develop a set of simulation training tools that can not only ensure safety but also effectively improve the practical level of trainees.
[0003] There are two main types of photovoltaic power station simulation training systems on the market: one is to directly use computer software for virtual simulation training. Although this type of system can simulate most of the power station operation processes through the computer display interface, it lacks the sense of reality of physical contact; the other is to use miniaturized and simplified physical equipment for teaching demonstrations. Although this solution increases the practical links, it lacks in comprehensive functions and fault simulation. Both solutions have their own advantages, but they also have obvious limitations.
[0004] On the one hand, the computer display interface virtual simulation software is not intuitive and cannot completely replace the on-site operation experience; on the other hand, the existing physical teaching aids are mostly single-point displays with single functions, which cannot cover all operating conditions during the entire power station operation cycle, and there are safety hazards of electric shock during learning, especially in the handling of abnormal situations, which limits the training effect. Summary of the invention

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: the multifunctional simulation training device of a photovoltaic power station proposed in the present invention comprises a preset practical photovoltaic unit and a 3D simulation system, the preset practical unit comprises a typical equipment structure library and an actual tool library, the typical equipment structure library comprises photovoltaic power station components and connectors, the actual tool library comprises tools for maintenance of photovoltaic power stations, the 3D simulation system comprises simulation components and simulation software, the simulation components comprises a VR head display device and a simulation monitoring screen, an operating lever and a simulation computer group, a wireless transmission device is provided in the simulation computer group, the VR head display device and the operating lever are both wirelessly connected to the simulation computer group, the simulation software is installed in the simulation computer group, the simulation software comprises a simulation working condition selection system, a simulation component matching library, a simulation tool selection library and an operation monitoring and training evaluation system, and the simulation monitoring information is synchronously displayed in the VR head display device.

[0008] Furthermore, the photovoltaic power station components and connectors include solar panels, inverters, controllers, load resistors and circuit breakers, and all have the same structure as actual units.
[0009] Furthermore, the simulation component matching library has a one-to-one matching correspondence with the photovoltaic power station components and connectors, the photovoltaic power station components and connectors are not actually electrically connected, and the simulation component matching library performs simulated operation and electrical connection.
[0010] Furthermore, the simulation tool selection library selects the required simulation tools according to the simulation working conditions, and matches them with the tools selected in the actual tool library, so as to match the simulation component matching library to simulate the inspection and maintenance.
[0011] Furthermore, the entry prompt explanation library provides entry explanations for photovoltaic power station components and connectors, actual tool library and tools selected by simulation tool selection library, and provides explanations and operation guidance for simulation working conditions.
[0012] Furthermore, the operation monitoring and training evaluation system is started synchronously with the 3D simulation system, and all operations in the 3D simulation system are recorded and monitored in real time, and real-time feedback is given to the simulation monitoring screen to generate a training report.
[0013] Furthermore, the simulation monitoring screen can directly call up the simulation components, simulation tools and corresponding term explanations in the simulation component matching library, the simulation tool selection library and the term prompt explanation library for providing teaching prompts to students.

[0017] 3. The multifunctional photovoltaic power station simulation training device proposed in this plan can achieve a high degree of restoration of the normal operation of the photovoltaic power station and various typical fault scenarios by integrating simulation modules and actual operation components, thereby improving the authenticity, practicality and fun of the training, and enabling trainees to acquire more practical experience in a safe environment.

The preset practical photovoltaic unit contains a typical equipment structure library and an actual tool library. The typical equipment structure library includes photovoltaic power station components and connectors. The actual tool library includes tools for photovoltaic power station maintenance. The 3D simulation system includes simulation components and simulation software. The simulation components include a VR head display device and a simulation monitoring screen, an operating lever and a simulation computer group.

The simulation software is installed in the simulation computer group. The simulation software includes a simulation working condition selection system, a simulation component matching library, a simulation tool selection library and an operation monitoring and training evaluation system. The simulation software is synchronously displayed in the VR head display device.
[0023] like Figure 1-2 As shown, the simulation working condition selection system has the functions of autonomously selecting simulation working conditions and randomly selecting simulation working conditions. The simulation working conditions include the actual connection working status of photovoltaic power station components and connectors (to facilitate simulation of installation connection and routine maintenance of photovoltaic power station components and connectors) and typical failures and accidents of photovoltaic power station components and connectors (to facilitate simulation of photovoltaic power station components and connector troubleshooting and maintenance). Photovoltaic power station components and connectors include solar panels, inverters, controllers, load resistors and circuit breakers, and all have the same structure as actual units, which is convenient for students to directly contact actual units.
[0024] like Figure 1-2 As shown, the simulation component matching library and the photovoltaic power station components and connectors are matched one by one. The photovoltaic power station components and connectors are not actually electrically connected. Simulated operation and electrical connection are performed through the simulation component matching library to avoid safety accidents during simulation learning and reduce safety hazards. The simulation tool selection library selects the required simulation tools according to the simulation working conditions, and matches them with the tools selected in the actual tool library, so as to facilitate simulated inspection and maintenance of the simulation component matching library.
[0025] like Figure 1-2 As shown, the entry prompt explanation library provides entry explanations for photovoltaic power station components and connectors, the actual tool library and the tools selected by the simulation tool selection library, and explains the simulation working conditions and provides operation instructions. The operation monitoring and training evaluation system is started synchronously with the 3D simulation system, and all operations in the 3D simulation system are recorded and monitored in real time, and real-time feedback is given to the simulation monitoring screen and a training report is generated. The simulation monitoring screen can directly call up the simulation components, simulation tools and corresponding entry explanations in the simulation component matching library, the simulation tool selection library and the entry prompt explanation library for teaching prompts to students.
[0026] When used specifically:
[0027] S1: Trainees wear VR head-mounted display devices to enter the display interface, and connect the VR head-mounted display devices to the joysticks and the wireless transmission devices in the simulation computer group. The training teacher can observe the trainees' learning situation using the VR head-mounted display devices through the simulation monitoring screen, and start the operation monitoring and training evaluation system at the same time;
[0028] S2: The trainees use the joystick to input instructions to the simulation computer group to enter the simulation working condition selection system, and select the simulation working condition independently according to the prompts of the training teacher (the examination and test are in random selection mode);
[0029] S3: Students select relevant components of photovoltaic power station components and connectors in the typical equipment structure library according to the learning content, open the simulation component matching library to match the actual components of photovoltaic power station components and connectors to generate simulation connections, and use the combination of actual components and simulation to reduce safety hazards and improve the sense of learning reality;

[0031] S5: The term prompt explanation library can explain terms according to the corresponding simulated photovoltaic power station components and connectors in the VR head display device, the actual tool library and the tools selected in the simulation tool selection library, and explain the simulation working conditions and provide operation guidance (only appears in training mode, and is required to be blocked in examination mode). At the same time, the training teacher can directly call up the simulation components, simulation tools and corresponding term explanations in the simulation component matching library, simulation tool selection library and term prompt explanation library through the simulation monitoring screen to provide teaching prompts to the trainees;
[0032] S6: After the training, the operation monitoring and training evaluation system generates a training report, including the trainees’ scores, operation time, number of errors and other information. The training teacher can score through the simulation monitoring screen to help trainees understand their own level and improve.
