“…Then, a power electronics converter can be used to level the electrical energy [27]. PMSG used for direct-drive can be classified into three categories: i) axial-flux, ii) transverse-flux, and iii) radial-flux [28,29]. Radial-flux generator is generally used for high-power direct-drive.…”

Wind energy conversion systems (WECS) have developed rapidly in recent years in terms of capacity and wind turbines design. This development led to improve power quality, to reduce the costs and increase the energy yield. WECS are expected to be reliable, effective and more cost-competitive. A comprehensive analysis and review on electrical machines in WECS (viz., wind turbine generators) has been presented in this paper. Design, (dis) advantages, and market penetration of different wind turbine generators are analyzed and discussed. Some comparisons have been made on the permanent-magnet (PM) synchronous machines, promising generator for future wind turbines, especially offshore wind turbines.

“…In fact, this type of wind turbine is named as fixed speed wind turbine because they operate at a constant rotor speed. However, variable speed control could make the wind turbine always operate close the point of maximum power coefficient since variable rotor speed control, such as the figure [10] below shows.…”

One specific issue associated with the wind turbine is how to manage and adjust the rotor speed and pitch angle in the turbine with the wind increasing to achieve the maximum power extraction from the wind. The aim of this paper is to provide a summary study of the impact of related controls and operating strategies on the wind turbine which mean how parameters affect the wind turbine operation. The software of "GH bladed" produced by GL Garrad Hassan will be used to model wind turbine and to perform the analysis. Following two strategies, control of rotor speed and control of blade pitch angle, are applied to the model of the wind turbine to see how output power are adjusted and optimized. The final part proposes the operating strategy of the wind turbine to understand the running procedure of wind turbine inside.

“…Decreasing torque density of TFPM machinery should reduce the number of poles with low flux leakage. However, the main problems encountered by the rotating section of TFPM machinery are the difficult production methods and the large number of parts, resulting in a weak mechanical structure [5]. Currently, direct-drive (DD) electrical generators have become popular for wind turbines rated at 4 MW, and are also supplied for higher power wind turbines.…”

The application of wind turbine technology in low wind speed regions such as Southeast Asia has recently attracted increased attention. Wind turbines are designed as special structures with low starting torque, and many starting torque minimization processes exist for permanent magnet synchronous generators (PMSGs). Plurality is applied to decrease the starting torque in radial flux permanent magnet disk generators. The most popular starting torque minimization method uses a magnet skew technique. When used at 20°, this technique reduced starting torque by 4.72% (on load) under 500 rpm at 50 Hz for 120 min. By contrast, a PMSG with magnet skew conditions set at under 2° reduced electrical power by 3.86%. For high-speed PMSGs, magnet skew techniques affect the generation of heat in the coils (stator), with heat decrease at the middle of the coil, on its surface and between the coils at 2.90%, 3.10% and 2.40%, respectively. PMSGs were installed in vertical axis wind turbines (VAWTs), and heat generation in relation to wind speed and electrical power was assessed. Magnet skew techniques can be used in PMSGs to reduce staring torque, while skew techniques also reduce electrical power and heat generated at the stator.
