Direct-drive wind power system converter control strategy

Without gear device, low maintenance and low noise make permanent magnet direct drive wind power system attracts more and more attention., and it has became a important direction for future development of the variable speed constant frequency wind power system. To enhance the network operation capacity of the wind turbine, it is significant to study the control of the machine side and the network-side, due to dual PWM converter can realize a variety of control functions, the application in renewable energy and power system are more widely. In this paper, study for the full power back to back converter and set up a mathematical model to achieve the overall converter modeling, and through simulation system to verify the fast response.
