[0025] Specifically, the simulation platform includes an environmental variable acquisition unit and an equipment status simulation unit. The environmental variable acquisition unit is used to simulate the real environment of the wind turbine and generate environmental monitoring data.

[0026] The pitch training platform is used to simulate the pitch action of wind turbines. The yaw training platform is used to simulate the yaw action of wind turbines.

[0027] The main control unit is connected to the simulation platform, pitch training platform and yaw training platform respectively, and is used to generate pitch control signals and yaw control signals according to environmental monitoring data. In addition, the main control unit is also used to generate fault simulation signals according to different types of wind power electrical fault conditions, thereby triggering fault simulation of different components in the wind turbine.

[0028] The power supply unit is connected to the simulation platform, pitch training platform, yaw training platform and main control unit through cables to provide external power supply.

[0029] Furthermore, in a possible implementation, the environmental variable acquisition unit may include an anemometer, a wind vane, a navigation light, a vibration sensor, a temperature measuring element, a pressure sensor, and a humidity sensor.

[0030] Furthermore, in a possible implementation, the device status simulation unit may include a control cabinet, a travel switch, a low-voltage electrical component, and a switch control device, and the travel switch, the low-voltage electrical component, and the switch control device are all integrated in the control cabinet.

[0031] Furthermore, in a possible implementation, the pitch control training platform may include a pitch control module, a blade position monitoring component, a pitch drive motor, and a pitch drive component.

[0032] Among them, the blade position monitoring component is used to obtain the blade position information. For example, the blade position monitoring component may include: a variable pitch position indicator, a 3-5 degree position sensor, an 89 degree position sensor, a 91 degree limit switch, and a 95 degree limit switch. The 3-5 degree position sensor is used to detect the current position of the blade; the variable pitch position indicator is used to display the current position of the blade; the 89 degree position sensor is used to detect whether the blade is in place; the 91 degree limit switch is used to detect whether the blade has reached the warning position of 91 degrees; and the 95 degree limit switch is used to detect whether the blade has reached the extreme position of 95 degrees.

[0033] The pitch control module is used to control the start of the pitch drive motor according to the pitch action control signal sent by the main control unit, and to control the stop of the pitch drive motor according to the blade position information.

[0034] The pitch drive assembly is connected to the pitch drive motor through a signal line, and is used to receive the rotational power of the pitch drive motor to drive the blades to rotate. The pitch drive assembly can be composed of a proportional reduction gear and a lead screw.

[0035] Further, in a possible implementation, the yaw training platform may include a yaw motor, a yaw drive assembly, a housing, and a yaw position indicator. The yaw motor, the yaw drive assembly, the yaw position indicator, the twist switch, and the yaw limit switch are all integrated in the housing.

[0036] In addition, a twist switch and a yaw limit switch can also be set in the box, wherein the twist switch is used to detect the twisting condition of the cable, and the yaw limit switch is used to detect the extreme position of the yaw of the yaw training platform.

[0037] Furthermore, in a possible implementation, a hydraulic training unit can be provided on the basis of the existing structure of the yaw training platform. The hydraulic training unit is connected to the yaw drive assembly to simulate the yaw braking action. For example, a set of hydraulic stations, hydraulic supporting pipelines, yaw brake calipers and high-speed brake calipers can be added on the basis of the existing structure of the yaw training platform. The hydraulic station is connected to the yaw brake caliper and the high-speed brake caliper respectively through the hydraulic supporting pipelines. The yaw brake caliper and the high-speed brake caliper realize the braking action by receiving the main control signal sent by the main control unit or manually pressing.

[0038] Furthermore, in a possible implementation, the wind power training teaching system may further include a frequency converter training platform. The frequency converter training platform is respectively connected to the pitch training platform and the yaw training platform to implement frequency conversion control.

[0039] In order to better understand the above exemplary embodiments of the present invention, they are further described below in conjunction with specific examples and drawings.

[0040] Example 1 like Figure 1 As shown, a comprehensive wind power training teaching system can be composed of a power supply unit 1, a main control unit 2, a simulation platform 3, a frequency converter training platform 4, a projection TV 5, a pitch training platform 6 and a yaw and hydraulic training platform 7.

[0041] Among them, the power supply unit 1 is used to provide external power supply, and is connected to the main control system cabinet through a cable to ensure the normal operation of the system. The power supply unit includes a power indicator light, a voltmeter, a switch button, a main switch Q1, a switch Q2, a switch Q3, a switch Q4 and a contactor KM1. The main switch Q1 uses a 250A / 380V molded case circuit breaker to control the power supply of the entire system. The switch Q2 uses a 200A / 380V molded case circuit breaker to control the power supply of some systems. The switch Q3 uses a 50A / 380V molded case circuit breaker to supply power to the variable pitch training platform, and has the function of controlling the power supply by the switch button. The switch Q4 uses a 50A / 380V molded case circuit breaker to supply power to other parts. The contactor KM1 uses 50A / 380V to control the on and off of the main power supply line to ensure safe power supply. The Q3 power supply that supplies power to the unit has the function of controlling the power supply by the switch button.

[0042] The simulation platform mainly provides necessary environmental monitoring and equipment status data for system operation, and feeds back to the main control unit in the form of analog signals to realize the logical control of simulated wind turbines in real environment and status. Figure 2 As shown, the simulation platform is divided into two parts: an environmental variable acquisition unit 31 and an equipment status simulation unit 32. The environmental variable acquisition unit 31 is composed of platform brackets, anemometers, wind vanes, beacon lights, vibration sensors, temperature measuring elements, pressure / pressure differential sensors, humidity sensors, proximity switches and other components, and the anemometers, wind vanes, beacon lights, vibration sensors, temperature measuring elements, pressure / pressure differential sensors, humidity sensors and proximity switches are all integrated on the platform bracket. The equipment status simulation unit 32 is composed of a control cabinet, a travel switch, a low-voltage electrical component and a switch control device, and the travel switch, the low-voltage electrical component and the switch control device are all integrated in the control cabinet. The environmental variable acquisition unit can collect environmental variables in real time and feed the data back to the main control unit, and the control cabinet sets different hardware line faults through integrated switches and terminals. During the training process, the selection and setting of different fault points can be realized by disconnecting different switches, ensuring that the fault point setting is fast and efficient, and improving the safety and stability of the system.

[0043] The variable pitch training platform 6 is mainly composed of three parts: the platform bracket assembly, the variable pitch control assembly and the variable pitch drive assembly. Among them, the bottom bracket of the variable pitch bracket assembly is connected to the ground and the variable pitch control module, and the upper part of the bracket supports the variable pitch drive assembly. The variable pitch control assembly consists of a variable pitch control module, a 3-5 degree position sensor, an 89 degree position sensor, a 91 degree limit switch, and a 95 degree limit switch. The variable pitch drive assembly is located at the top of the variable pitch training platform and consists of a variable pitch drive motor, a proportional reduction gear, a lead screw, and a variable pitch position indicator. The variable pitch training platform is connected to the main control unit via CAN communication, and provides real-time feedback on the blade position and system status, and receives main control instructions to perform propeller opening and propeller feathering actions. The overall action process is that the main control unit gives a pitch action control signal (such as a pitch action control signal containing a pitch opening instruction). After the pitch control assembly receives the pitch action control signal, it controls the pitch drive assembly to move. The pitch motor starts to drive the proportional reduction gear to rotate, and the rotation is transmitted to the pitch position indicator through the lead screw to feedback the pitch opening position. When the position indicator reaches 89°, the pitch motor stops to complete the pitch opening action, and the same applies to the pitch adjustment. In addition, the pitch training platform can also realize functions such as pitch zeroing, pitch self-learning, and pitch fault simulation. The pitch training platform can realize the operation and control of the pitch system by receiving the main control signal from the main control unit or manually giving instructions, which can meet the training function requirements such as pitch operation demonstration, hardware disassembly, fault simulation, maintenance and repair.

[0044] The yaw and hydraulic training platform 7 is an integrated design of the yaw system and the hydraulic system, covering the yaw training function and the hydraulic training function. Among them, the yaw training platform consists of two parts: a yaw drive assembly and a box assembly. The yaw drive assembly is composed of a yaw motor, a yaw reducer and a drive gear system, and the box assembly includes a box, a yaw position indicator, a torsion cable switch and a limit switch. By adding a hydraulic station, hydraulic supporting pipelines, a yaw brake caliper and a high-speed brake caliper to the existing structure of the yaw training platform, the simulated yaw brake and high-speed shaft brake functions can be realized. Figure 3 As shown, the yaw and hydraulic training platform is directly controlled by the main control unit. The main control unit controls the hydraulic station 75 to realize the braking action of the high-speed brake caliper 71 and the yaw brake caliper 74. The yaw drive assembly 72 and the box assembly 73 realize the yaw action and position indication function. At the same time, the cable switch and the limit switch realize the feedback and control of the yaw limit position. In this way, the yaw and hydraulic training platform realizes the yaw action and automatic cable release by receiving the main control signal sent by the main control unit, which can realize the training needs such as action demonstration, fault simulation, hardware disassembly, maintenance and repair. In addition, the yaw and hydraulic training platform can realize the braking action by receiving the main control signal sent by the main control unit or manually pressing.

[0045] The main control unit is the core of the system and is responsible for coordinating data interaction and logic control between various platforms. It can be divided into two parts: human-machine interaction module and main control module. The main control module consists of control cabinet, power module, PLC module, digital I / O module, analog I / O module, communication module, low-voltage components, etc.; the human-machine interaction module consists of industrial control screen and supporting HIM software.

[0046] like Figure 4 As shown in the figure, the overall connection and interaction system diagram between the platforms is displayed. The main control unit receives the data fed back by each platform, gives control instructions through logical judgment, and synchronizes the operation status and data of each platform to the human-computer interaction module, and the HMI displays dynamic information in real time. During the training, trainees can understand the operation status of the platform through the HMI, determine the location of the fault point and issue instructions to the system. In addition, they can modify and debug the control logic and parameters through the configuration software to simulate the operation under actual working conditions.

[0047] The inverter training platform 6 realizes data exchange with the main control unit through CAN communication. It is mainly composed of an inverter and supporting accessories, and can realize the training functions such as inverter hardware disassembly, software operation, fault simulation, maintenance and repair. Since the inverter fault point is not displayed in detail in the main control unit and there are differences in the fault point settings of inverters from different manufacturers, it is necessary to directly connect the PC to the inverter to view the fault information and corresponding debugging operations during the training process, which will not be repeated here.

[0048] The projection TV 5 is used to display the training content.

[0049] Based on the operation content of the wind farm and the ability requirements for maintenance personnel, this comprehensive training platform can carry out training tasks including but not limited to physical recognition and disassembly, simulated control and debugging operations, fault setting and troubleshooting, etc. The following three examples illustrate the platform functions and applications: Physical recognition and disassembly of wind turbines: Taking the simulation platform as an example, the platform basically covers all kinds of sensors and low-voltage electrical components currently used in wind turbines, including but not limited to conventional temperature measuring elements PT100, precision vibration sensors, high-sensitivity pressure sensors, precise travel limit switches, advanced wind speed and direction measuring instruments, and various types of contactors and air switches. At the physical learning level, students can use this platform to intuitively understand and deeply explore the various electronic components of wind turbines, and through a meticulous disassembly process, deeply understand their internal structure and working mechanism. At the application practice level, the platform encourages students to independently build connections between hardware components and control systems, so as to master the precise collection and efficient output process of environmental variables. For example, by using the connection between the Bachmann PTAI216 module and the PT100 temperature measuring element, and with the help of the powerful functions of the PLC (programmable logic controller), students can achieve real-time and accurate monitoring of ambient temperature. This process not only enhances students' understanding of hardware and software integration, but also significantly improves their ability to solve practical problems. Wind turbine simulation control and debugging: The main control unit can realize custom programming and filling operations of software programs, and issue operation instructions to other platforms through logical control. Taking simulated yaw control as an example, the simulation platform collects wind speed and wind direction values ​​and transmits the values ​​to the main control unit. When the main controller PLC determines that the current wind speed value is greater than the set value of 2.5 m / s and the average wind direction deviation of 30 seconds is greater than 10°, it sends instructions to the yaw and hydraulic training platform. At this time, the hydraulic system in the yaw and hydraulic training platform is semi-depressurized, the yaw motor starts and drives the yaw reducer at the same time, and the yaw reducer drive gear rotates to drive the platform position indicator to move. When the position deviation is 0°, the yaw stops and the hydraulic system brakes to complete the simulation control of the yaw action. In this process, students can manually issue control instructions through the HMI interface, or modify the control logic and parameters through the main control program editing software, and further master the debugging and calibration operations between systems through physical action correction and logical control comparison. Fault setting and troubleshooting: Compared with mechanical system failures, electrical systems in units show a higher frequency of faults, more complex troubleshooting challenges, and higher requirements for the professional skills of maintenance personnel. This comprehensive training platform integrates a detailed wind power electrical fault case library, achieving comprehensive coverage of key parts such as unit main control failures, pitch failures, inverter failures, yaw failures, hydraulic failures, and communication interruptions. Through innovative system fault injection technology and flexible hardware loop configuration, the platform can simulate fault triggering in a real environment. In addition, the platform also has fault locking and holding functions to ensure that students have enough time for in-depth analysis; the integrated HMI (human-machine interface) system displays fault information in real time to help quickly locate the root cause of the problem; the dynamic fault scenario restoration capability allows students to repeat exercises in a virtual environment to deepen their understanding.In the practical training phase, trainees can randomly select fault cases for actual combat exercises, or they can make targeted choices based on their personal learning needs, and gradually improve their fault handling speed and accuracy by customizing time limits, thereby comprehensively enhancing the fault diagnosis and repair capabilities of the electrical system. In summary, the present invention provides a comprehensive teaching platform system that integrates theoretical learning, practical operation, fault diagnosis and resolution, and its effects are specifically manifested in the following aspects: (1) Combination of theory and practice: The platform not only provides opportunities for physical display and disassembly of various components of wind power systems, but also enables trainees to perform practical operations in a close-to-real working environment through a simulation system, effectively promoting the deep integration of theoretical knowledge and practical skills; (2) Improvement of fault simulation and diagnosis capabilities: Through the built-in fault simulation system, trainees can be exposed to and handle various fault situations that may be encountered in wind power systems. This greatly improves their ability in fault diagnosis and resolution, laying a solid foundation for rapid response and problem resolution in future practical work; (3) Flexibility and scalability: The platform supports custom programming and filling operations, allowing students to adjust control logic and parameters according to actual needs. This not only enhances the flexibility of teaching, but also provides students with space for exploration and innovation, helping to cultivate their innovative thinking and problem-solving abilities. (4) Efficient teaching and training: Through the integration of the HMI interface and the main control program, the teaching process is more intuitive and efficient. Trainees can see the operation results in real time, provide feedback and make adjustments, thereby accelerating the learning process and improving training efficiency.
