The maximum power control of direct-drive wind turbine

The direct-drive wind turbine has become a focus recently for wind power generation because it has many advantages, such as simple construction, high reliability and so on. In this paper, a permanent magnet wind power generation system based on coordination control of double PWM is presented. And one dynamic model of permanent magnet synchronous generator (PMSG) is established on the basis of taking the improved tip speed ratio as control variables. The effectiveness of the established model and proposed control strategies are validated by the software platform of MATLAB/SIMULINK and the operation performances of the control strategies meets requirements.
