Figure 1 The simulation training system for the wind turbine generator set includes a software subsystem 10, a simulation subsystem 12, a control subsystem 14, and a data monitoring subsystem 16. The software subsystem 10 includes at least one instructor port 102 and at least one student port 104. Each student port 104 corresponds to its own simulation subsystem 12, control subsystem 14, and data monitoring subsystem 16.

[0032] This embodiment introduces a software subsystem and a simulation subsystem. The software subsystem can connect multiple instructors and multiple students, while the simulation subsystem can effectively simulate wind turbine generators. Through the software subsystem and the simulation subsystem, a simple and effective bridge is established between learners and the simulated operation of wind turbine generators, enabling learners to conduct comprehensive and convenient simulation learning of wind turbine generators.

[0033] Specifically, the aforementioned simulation training system can adopt a browser / server (B / S) architecture, meaning it can be accessed via a webpage. For example, instructors can log in through a first terminal (hereinafter referred to as the instructor's terminal) on the instructor port of the software subsystem, and students can log in through a second terminal (hereinafter referred to as the student's terminal) on the student port of the software subsystem. The instructor and student terminals can embed network relays for communication between them; other communication methods can also be used, and this disclosure does not limit this. The aforementioned simulation subsystem can simulate the operation of a wind turbine generator using a BLADED model; other models can also be used, as long as they can simulate the operation of a wind turbine generator, and this disclosure does not limit this either.

[0034] According to embodiments of this disclosure, the control subsystem receives input information from corresponding instructor ports and corresponding student ports, and controls the simulation subsystem to operate based on the input information. This may include: the control subsystem receiving first input information from the corresponding instructor port, wherein the first input information includes trigger information that triggers a first fault in the wind turbine generator set; and the control subsystem controlling the simulation subsystem to operate based on the trigger information. According to this embodiment, the instructor can use the first input information to lay out the faults that the student needs to learn, so as to provide targeted training to the student.

[0035] Specifically, instructors can use the first input information entered through the instructor port to set the faults that trainees need to learn. That is, by using the first input information, the instructor can set the trigger information to trigger the corresponding faults of the wind turbine generator set. During operation, the simulation subsystem can trigger the corresponding faults based on the trigger information. Thus, trainees can understand the corresponding faults through the operation data of the simulation subsystem and learn how to deal with them.

[0036] According to embodiments of this disclosure, the control subsystem receives input information from corresponding instructor ports and corresponding student ports, and controls the simulation subsystem to operate based on the input information. This may include: the control subsystem receiving second input information from the corresponding student port, wherein the second input information includes solution information for a first fault, the first fault being obtained based on the simulation subsystem's operational data monitored by the data monitoring subsystem; and the control subsystem controlling the simulation subsystem to operate based on the solution information. According to this embodiment, the student can determine the fault based on the operational data, input the corresponding solution information, and control the simulation system to operate until the fault is resolved, thereby learning methods for handling faults.

[0037] Specifically, trainees can view the operational data of the simulation subsystem monitored by the data monitoring subsystem, analyze the operational data to determine the faults of the wind turbine generator set, determine the corresponding solutions based on the analyzed faults, and input the determined solution information into the control subsystem of the simulation training system through the trainee port. The control subsystem can then control the operation of the simulation subsystem based on the input solution information and check whether the operation process has resolved the aforementioned faults. If not, the solution can be adjusted until the aforementioned faults are resolved.

[0038] According to embodiments of this disclosure, the control subsystem controls the operation of the simulation subsystem based on solution information. This can include: the control subsystem assigning parameters contained in the solution information to the corresponding electrical parameters of the simulation subsystem, and controlling the operation of the simulation subsystem based on the assigned electrical parameters. According to this embodiment, by directly assigning simulation permissions, a simple connection between the simulation and the simulated wind turbine generator is achieved, allowing trainees to experience the simulation learning process firsthand and resolve corresponding faults.

[0039] According to embodiments of this disclosure, the control subsystem receives input information from corresponding instructor ports and corresponding student ports, and controls the simulation subsystem to operate based on the input information. This may include: the control subsystem receiving third input information from the corresponding student port, wherein the third input information includes control parameters for controlling the simulation subsystem to operate in a predetermined manner; and the control subsystem controlling the simulation subsystem to operate based on the control parameters. According to this embodiment, the control simulation subsystem can be learned through the third input information, simulating and experiencing the control of a wind turbine generator.

[0040] Specifically, trainees can input control parameters through the trainee port to control the simulation subsystem to operate in a predetermined manner, so that the control subsystem can control the operation of the simulation subsystem according to the control parameters. In other words, trainees can simulate the control of the operation of the wind turbine generator by inputting control parameters and learn how to control the wind turbine generator.

[0041] According to embodiments of this disclosure, the data monitoring subsystem includes a local monitoring unit and a data acquisition and monitoring control unit. The local monitoring unit monitors the operation of the simulation subsystem and displays the monitored operational data to the students at the corresponding student ports and the instructors at the corresponding instructor ports. The data acquisition and monitoring control unit monitors the operation of the simulation subsystem and determines the operating status of the wind turbine generator based on the monitored operational data, displaying the operating status to the students at the corresponding student ports and the instructors at the corresponding instructor ports. According to this embodiment, the local monitoring unit, the data acquisition and monitoring control unit, and the monitoring control unit jointly monitor the operation of the simulation subsystem to obtain accurate operational data.

[0042] Specifically, the data monitoring subsystem of the aforementioned simulation training system may include a local monitoring unit, a data acquisition and monitoring control unit, and of course, other units for acquiring operational data; this disclosure does not limit this. Trainees can obtain various operational data through the local monitoring unit and the data acquisition and monitoring control unit to perform fault analysis, rather than relying on a single type of operational data. This makes fault analysis more accurate and also makes the analysis of whether the wind turbine generator is operating normally more accurate when troubleshooting. At the same time, instructors can also obtain various operational data through the local monitoring unit and the data acquisition and monitoring control unit to perform fault analysis, again moving away from relying on a single type of operational data. This makes fault analysis more accurate and also makes the analysis of whether the wind turbine generator is operating normally more accurate when troubleshooting.

[0043] According to embodiments of this disclosure, the simulation training system further includes a dedicated communication unit. At least one instructor port and at least one student port communicate with the control subsystem and the simulation subsystem through the dedicated communication unit. According to this embodiment, the dedicated communication unit facilitates convenient and rapid communication.

[0044] Specifically, the aforementioned dedicated communication unit can be an ADS (Automation Device Specification), or of other types, and this disclosure does not limit it.

[0045] For example, the aforementioned student terminal can embed an ADS communication unit, such as an ADS application programming interface (API), and communicate with the control subsystem (such as a PLC controller) and simulation subsystem through the embedded ADS communication unit. The aforementioned student terminal can also communicate with the data monitoring subsystem (such as a Supervisory Control and Data Acquisition, abbreviated as SCADA) through the embedded ADS communication unit, or through a PLC controller and simulator (MODBUS TCP). This disclosure does not limit the scope of the communication.

[0046] It should be noted that the simulation subsystem and control subsystem may also embed an ADS communication unit, and this disclosure does not limit this.

The role management subunit allows for the addition, deletion, modification, searching, and maintenance of roles. It can maintain the association between roles and users, link existing users, and maintain the static menu permissions for roles.

It also supports setting menu button permissions. The user management subunit can be maintained manually or automatically created from template imports. It supports user locking, user activation, password reset, batch import / export, and searching by username and real name.

[0052] For example, the aforementioned basic data management unit may include a tag management subunit, a PLC trigger point management subunit, a theoretical simulation question bank subunit, a tool management subunit, a spare parts management subunit, and a potential fault point management subunit. Of course, it may also include other subunits, as long as they are set according to user needs. This disclosure does not limit this.

Of course, it may also include other subunits, as long as they are set according to the user's needs. This disclosure does not limit this. The simulation exam paper management subunit allows administrators to input, edit, and view theoretical exam papers. Administrators can input exam paper information, such as the total score for multiple-choice, true / false, and single-choice questions, and then click the "Start Generating Exam Paper" button to automatically generate the exam paper. Clicking the "Submit" button will display the generated theoretical exam paper.

Administrators can view all data, while other users can view data from their own department and lower-level departments. The system also supports fuzzy searches by category, exam time, score sorting, exam name, and candidate name, and allows browsing exam paper information from multiple exams.

[0054] It should be noted that the instructor's simulated exam management permissions include operations such as adding, viewing, modifying, and deleting. Instructors can view exam papers but do not have editing functions, and can also query pending exam papers and exam history statistics. The student's simulated exam management permissions include: practical exams, theoretical exams, and viewing exam details. For example, clicking on the pending exam paper sub-unit allows students to view the pending exam papers assigned to them by the instructor. The student permission display page for the aforementioned pending exam papers shows all relevant exam papers, supported categories, exam times, exam names, and number of attempts.

[0055] Specifically, the functions displayed on the page showing student access permissions for exam papers are described as follows:

[0056] Exam Paper Display: The interface displays all the exams and exam papers under the candidate's name.

[0057] Tag Classification: The "All" category tag allows you to search for all exam papers under a candidate's name.

[0064] Specifically, the aforementioned engine room substation detects the simulated generator speed signal (i.e., the speed information in the above embodiment) in the simulation subsystem and sends the generator speed signal to the drive unit. Furthermore, the engine room substation is connected to the simulation unit and interacts with it to exchange engine room simulation signals, as detailed below. Figure 3 As stated above.

[0065] According to embodiments of this disclosure, the pitch unit may include at least one pitch substation and a pitch platform connected to the at least one pitch substation. The power grid unit includes a power grid and a transformer, with the power grid connected to the converter unit and the drive unit respectively through the transformer. The above-described configuration of this embodiment can effectively simulate a wind turbine generator set.

[0066] To facilitate understanding of the above embodiments, the following example uses a browser / server (B / S) architecture system for PC-based simulation training of wind turbine generator set maintenance and operation.

At this point, the simulation subsystem has a total of 40 simulators. Figure 5As shown, each simulator represents an independently operating wind turbine generator. The simulator uses a BLADED model to simulate the operation of the wind turbine generator. Simultaneously, the simulator embeds an ADS communication unit, which interacts with the software subsystem to receive trigger information from the software subsystem that indicates a fault in the wind turbine generator. Based on this trigger information, the corresponding fault is triggered. SCADA (equivalent to the aforementioned data monitoring subsystem) obtains the simulator's operating data through MODBUS TCP communication with the simulator.

Alternatively, all electrical signals connected to the PLC from the simulator can be assigned values ​​through the ADS port, transmitting the information of the corresponding fault solution to the simulator. This allows the simulator to operate based on the solution to overcome the fault.
