The Application of Direct Power Control in Permanent Magnet Direct Driven Wind Power System
With the multi-variable, nonlinear and strong coupling features of the Permanent magnet direct driven wind turbines,the parameter vector control of the system would be influenced on the change of parameters of the system.Based on the analysis and reflection on the presently existing control strategies for the problem of direct-driven PMSG wind Turbines controlling,this article proposes a control method, namely, Direct Power Control which can eliminat the link of current loop, reduce the coordinate and simplifie the algorithm of control. This control method has been run in the simulat environment, which further verified the feasibility of this method. Furthermore, we built this improved method on DSP FPGA.The result apparently showed that this method is effective.
