“…Switch fault is commonly occurred in the power electronic converter that produce high electrical, thermal stress, gate drive fault or wire disconnection that may cause various switch faults 3‐5 . The DFIG system's normal operations are affected by the switch fault, which causes critical issues like high current pulse, over current stress, and open phase process 6‐8 . Determination between the actual systems and mathematical models is used for the important issue of open and short circuit switch faults of the power electronic component 9,10 …”

Summary In this manuscript, a novel Kernel PCA‐ESMO technique is proposed for protecting the system and diagnosing the exact fault occuring in the DFIG. The proposed method is joined implementation of Kernel principal component analysis (Kernel PCA) and enhanced Spider Monkey Optimization SMO (ESMO) technique, and, hence, it is named Kernel PCA‐ESMO approach. Here, two phases are considered for fault analysis; they are fault identification and diagnosis. Primarily, the first phase identifies the system fault conditions of DFIG in grid‐connected system using Kernel PCA approach. After that, the ESMO classifies the type of fault that has occurred in the DFIG. The major scope of the proposed Kernel PCA‐ESMO method is to guarantee the system with less complexity for fault identification and diagnosis for enhancing the power quality of whole system. The implementation of proposed model is made at MATLAB/Simulink, and implementation is evaluated by existing techniques. The statistic analysis of proposed and existing systems of mean, median, and SD is analyzed. The efficiency of proposed and existing technique is also evaluated. The obtained values for percentage recall and precision that are enhanced using proposed technique are 97.8% and 98%. Consequently, the simulation outcome indicates that the efficiency of proposed technique and implementation of proposed strategy is compared to existing systems.

“…Moreover, the utilization of reduced converter ratings decreases the cost of the complete WEGS 14,15 and due to simple and cheap construction, the DFIG is extensively utilized in the WEGS. The various methods to connect the windings (stator and rotor) of DFIG to the grid and back‐to‐back converter are discussed in References 16‐18.…”

This paper is inspired by the question, "if the multi-phasetransmission system becomes commercially possible in future, then which type of variable speed induction generators will feed electric power to multi-phase transmission system?" In this paper, a novel six-phase DFIG through Asymmetrical Winding Structure is developed to extract electric power from the wind energy generation system (WEGS). Due to the spread of pandemic disease (Covid-19), the attention of power engineers is increasing toward the reliability (in terms of fault tolerance capability) of AC generators. The principle contribution of this manuscript is the modeling (mathematical and simulation-based modeling) of novel asymmetrical six phase doubly fed induction generator (ASPDFIG). Furthermore, this paper presents the complete modeling of WEGS which contains the modeling of supporting components (6-phsase transformer, appropriate rotor side converter, grid side converter, dc link etc.), aerodynamic system. In addition to modeling, the analysis, and the controlling strategy for ASPDFIG, wind turbine also discussed. The elegant advantages such as fault tolerance, high efficiency, reduced torque pulsation and reduced per leg converter rating of ASPDFIG are also discussed. The simulation results, particularly the stator voltage, phase current, active and reactive power, are given to validate the theoretic investigation.

“…Consequently, the availability of reactive power is maximized in the event of grid faults. 20 WECS which deploy DFIG, can be operated to deliver reactive power to the grid for providing low voltage ride-through during grid voltage dips. 21 DFIG can be controlled to improve the power sharing in micro-grid with other types of generators which are unable to support the grid during faults.…”

The insertion of renewable power generators into the power system network has been promoted by the environment protection aspects. Doubly fed induction generator (DFIG)-based wind energy system is one of the most viable technologies for sustained power generation. This paper focuses on the operational analysis of DFIG-based wind energy conversion systems (WECS) with real-time experimental validation. An event analysis is executed under sub-synchronous and super-synchronous speeds with the variation in wind velocity and reactive power exchange by controlling the rotor side converter and grid side converter under MATLAB/Simulink platform. The results of the analysis with reactive power exchange can be utilized for the enhanced control of power electronic converters of DFIG-based WECS for better support to the grid. The validation of results is accomplished by emulation of 2 MW DFIG-based three blade wind turbine system in the laboratory under a real-time hardware-in-the-loop platform.
