Abstract:In order to capture wind energy as much as possible, a maximum power point tracking control algorithm was proposed. The wind turbine performance of the direct-driven permanent magnet synchronous wind power system and the mathematical modeling of permanent magnet synchronous generator were analyzed and the maximum wind energy tracing strategy was improved. With Matlab/Simulink software, the entire system was simulated and researched. The results show that the algorithm is not only simple but also has high efficiency of utilizing wind energy, good tracking performance and good stability.
