This model consists of eight 1.5 MW wind turbines connected to a 25 kV distribution system which exports power to a 120 kV grid through a 30 km, 25 kV feeder. The eight 1.5 MW wind turbines form a wind farm of 12 MW of power. Figure 2.

Our turbines offer lower lifetime maintenance costs and shorter planned service cycles than traditional doubly-fed induction generator (DFIG) configurations. As a result of our passive and modular components, the absence of a gearbox, and an innovative pitch control system, our turbines offer improved reliability relative to our competition.

Introduction. In wind energy application, the Doubly Fed Induction Generator (DFIG) has a major advantage because its power converters require only 20–30% of the machine rating, for interfacing the rotor and the grid (Xu and Cartwright, 2006; Okedu, 2019) addition, the DFIG has cost effective power converters with low

In a doubly-fed induction generator converters (DFIG) wind turbine, the stator of the generator is directly connected to the grid. The rotor is connected to the grid through a back-to-back power converter. This speed-adjustable design is typically deployed in the power range between 1.5 MW and 6 MW.

In this section, a 2 MW stator power DFIG model and a three-blade wind turbine model with gear ratio n = 100, blade radius 42 m, Cp = 0.42, and λopt = 7.2 were used for the wind turbine maximum power point tracking simulation control as shown in Figure 21.

Direct-in-line wind turbine system. To develop decoupled control of active and reactive power, a DFIG dynamic model is needed. The construction of a DFIG is similar to a wound rotor induc-tion machine (IM) and comprises a three-phase stator winding and a three-phase rotor winding. The latter is fed via slip rings.

Therefore, an accurate analysis study of the effectiveness and robustness performance of the doubly fed induction generator (DFIG) is one of the challenges in wind turbine applications.

It allows the DFIG WTG to ride through the fault, without the need of crowbar protection which may generate disturbances to the DFIG WTG operations. More importantly, for the protection of the DFIG rotor speed, the proposed FPR scheme can better restrict the rotor speed variation during and after the fault as observed in Figure 12(d),
