https://doi.org/10.4467/2353737XCT.15.043.3843This article presents a variable-speed converter system for wind energy conversion. The considered system consists of a wind turbine with a permanent magnet synchronous generator (PMSG), a machine-side converter, a grid-side converter and control circuits. Mathematical models of the components of the wind energy system are described. The control algorithms of the converter systems based on the vector methods of control are also described. The considered wind energy system were studied by digital simulation. The simulation results are presented and discussed.

https://doi.org/10.4467/2353737XCT.16.256.6055The paper presents the wind energy conversion system with a direct driven Permanent Magnet Synchronous Generator (PMSG). The system consists of a wind turbine with a PMSG, the Machine Side Converter (MSC) and the Grid Side Converter (GSC). In order to control the MSC, the Direct Torque Control with Space Vector Modulation (DTC-SVM) has been applied. To achieve the maximum power from the wind turbine, the Maximum Power Point Tracking algorithm has been used. In order to control the GSC, the Direct Power Control with Space Vector Modulation (DPC-SVM) has been used. In order to obtain high power quality, the LCL grid filter has been used in the GSC. The performed simulation studies confirmed the high effectiveness of the Direct Torque and Direct Power control method.
