“…The annual energy production is considered for performance comparison of the designed DFIGs in a wind energy conversion system, based on the annual wind speed data of a region. The fundamental parameters and coefficients of the wind turbine are detailed in [30]. The probability distribution function is created using wind data collected over a year, and this function is utilized to determine the average annual power output, as depicted in figure 11.…”

Currently, both limited fossil fuel resources and environmental factors have increased the use of renewable energy sources. Renewable energy resources, such as wind energy systems, are gaining popularity, resulting in increased competition among manufacturers. This study aims to achieve a cost-efficient wind energy conversion system by designing and analysing the performance of a 250 kVA aluminium wound double-fed induction generator (DFIG). The advantages and disadvantages of aluminium windings are compared to those of copper windings, and three DFIG models are created: Model-1 with a copper winding set, Model-2 with the same geometry as Model-1 but designed with an aluminium winding set, and Model-3 with an aluminium winding set and slightly different stator and rotor diameters. The three DFIG models were analysed using finite element analysis (FEA) in ANSYS Maxwell, and the simulation results were obtained. According to the FEA results, Model-1 with copper windings had a higher efficiency compared to Model-2 with aluminium windings, but Model-2 had better cost and weight performance compared to Model-1. Model-3 and Model-1 had similar efficiencies, but Model-3 had slightly greater torque ripple compared to Model-1 due to a slightly different stator and rotor diameter. Although the total machine weight of aluminium-wound DFIGs was slightly increased, the total manufacturing costs were less than copper-wound DFIGs at the same efficiency levels.

The stability of a wind turbine-rotated synchronous generator must be maintained during a sudden change in wind speed or direction. In integral slot winding machines this task is taken care of by rotor damper windings. Tooth-coil permanent magnet generators cannot, however, have a damper winding in the rotor because of the high harmonic content of the air gap. In this paper, we study a possibility to stabilize PMSG damperless synchronous operation by dividing the generator stator winding into two parts -power winding (PW) and control winding (CW). We call this machine a dual-port PMSG (DPPMSG). The PW is directly connected to the grid. Therefore, the generator rotates, in average, at a fixed speed. On the other hand, the CW is connected to the grid through a four-quadrant power converter. The CW has three different tasks: It is responsible for the startup process, damping of speed oscillations and, of course, power generation. Electrical and magnetic decoupling of the winding sets is ensured by concentrated wound coils. The number of stator coils allocated to a winding set determines its power level. Different power levels of winding sets are analytically analyzed for wind gust speeds according to the IEC 61 400 standard. The results are verified by experimental tests.

“…For rural and remote areas, small‐scale standalone variable speed wind power generation systems (VSWPGSs) are widely used to extract more power by regulating the rotor speed and also to have better aerodynamic efficiency 4–6 . In the low power segment (<5 kW), permanent magnet synchronous generator (PMSG) is a good choice since it does not require external DC supply for the excitation, elimination of gear box, low maintenance, smaller size, and also generates significant torque even under low wind speed 7–9 …”

Summary Due to the stochastic and unpredictable nature of wind speed, extraction of maximum power from the wind turbine system becomes an attractive control objective. Therefore, to capture more wind power, various conventional maximum power point tracking (MPPT) schemes are developed for standalone small‐scale variable speed wind power generation system (VSWPGS). This manuscript proposes novel adaptive step size (ASS) and drift‐free ASS (DF‐ASS) MPPT methods for a permanent magnet synchronous generator (PMSG)‐based VSWPGS. The control schemes achieve maximum power point (MPP) without using mechanical sensors like speed encoder and anemometer. The proposed MPPT controllers are implemented on a laboratory‐scale DC motor‐PMSG‐based wind power generation system (WPGS) using OPAL‐RT real‐time digital platform. The ASS and DF‐ASS methods capture more power, reduce the steady‐state power oscillation around MPP, and improve the tracking speed. Also, the proposed DF‐ASS control scheme avoids drift phenomenon during wind speed increase condition. The comparative experimental results of proposed ASS and DF‐ASS methods with respect to the fixed step size MPPT schemes show better dynamic and steady‐state performance, making it pertinent for small‐scale WPGS.
