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

Method In this paper, a hardware-in-the-loop co-simulation system architecture based on Bladed and HiGale was proposed. Real-time co-simulation between Bladed and HiGale was realized via BHTM for the hardware-in-the-loop testing of wind power system controllers. Took a typical semi-direct-drive permanent magnet synchronous wind turbine as an example, a hardware-in-the-loop test model was established, which mainly consisted of a wind field model, a mechanical transmission model, and an electrical model. Using the co-simulation platform, the hardware performance was tested under three operating conditions: grid-connected control, pitch control, and low-voltage ride-through.

Result On the one hand, the experimental results verify the effectiveness of the grid-connected control and pitch control algorithms. On the other hand, they also demonstrate that the platform can provide reliable technical support during the development and testing stages of wind power generation systems.

Conclusion The results are of great engineering significance for improving system R&D efficiency and reducing R&D costs.
