With the development of wind power generation technology, the reliability and stability requirements of the main control system of wind turbines are becoming higher and higher.

[0003] The existing training systems for the operation and troubleshooting of the main control system of wind turbines usually adopt the method of hardware physical simulation. However, the existing training systems for the operation and troubleshooting of the main control system of wind turbines still have some problems and limitations in practical applications. First, the existing training systems can usually only simulate one or several faults, and cannot fully cover the types of faults that may occur in the main control system of wind turbines, which limits the types of problems and comprehensive troubleshooting methods that trainees can encounter during the training process. Secondly, the 3D display module of the existing training system can usually only statically display the operating status of the wind turbine, lacking dynamics and interactivity, which limits the trainees' comprehensive understanding and operation experience of the operating status of the wind turbine.
