Objective  The structure of the wind power generation system is complex, and in order to achieve efficient testing and control algorithm verification of the wind power generation system, it is necessary to simulate the wind power generation system in real time. At present, there is a lack of domestic real-time simulation and verification platform for wind power generation systems in the market.

  Method  A hardware-in-the-loop co-simulation system architecture based on Bladed and HiGale was proposed, and the real-time co-simulation of Bladed and HiGale through BHTM was realized for hardware-in-the-loop testing of wind power system controllers.

  Result  In this paper, a typical semi-direct drive permanent magnet synchronous motor wind power generation unit is taken as an example, and a hardware-in-the-loop accompanying test model is built, which is mainly composed of wind field model, mechanical transmission and electrical model, and the co-simulation platform was used to test the performance of the hardware under three working conditions: grid-connected control, pitch control and low-voltage ride-through.

  Conclusion  On the one hand, the experimental results verify the effectiveness of grid-connected control and pitch control algorithms. On the other hand, it is also proved that the platform can provide reliable technical support in the development and testing stage of wind power generation systems, which is of great engineering significance for improving system R&D efficiency and saving R&D costs.
