“…In this difficult situation, if faults occur in the stator winding of conventional doubly fed induction machine (DFIG), then the capable technician and engineers are unavailable to reach at power generation site (most probably at remote locations) for fault clearing purpose and resultantly reliability of the machine are affected. 1 Furthermore, when three phase induction machines are interfaced with conventional multi-step inverter then the pulsating component of torque are appearing in the machine and due to this pulsating torque, the vibrations are appearing in to machine. 2,3 The generators are widely utilized by renewable power industries for wind energy generation system (WEGS) and for establishing continuous power production using DFIG during the faults, the main requirements 4,5 for the DFIG system include the following:…”

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.

“…Asymmetrical six phase machines (A6P) are the most popular multiphase machines in most practical industrial applications, especially in ship propulsion and the oil and gas industry [2]. An asymmetrical six-phase machine comprises two three-phase stator windings having a spatial phase shift angle of 30°, while the two neutrals can either be connected or isolated [5].…”

“…The mathematical modelling of the A6P IM has been the objective of many research papers in the available literature [6]- [8]. The A6P IM is commonly modelled using either double or vector space decomposition (VSD) modelling techniques [2], [5]. VSD is usually employed in most recent literature since it completely decouples the phase variables into three orthogonal subspaces, namely, a single − torque producing subspace, one − secondary subspace, and a bidirectional zero-sequence subspace.…”

Improved Mathematical Modeling of Six Phase Induction Machines Based on Fractional Calculus

Multiphase induction machine modelling represents a crucial research topic for both machine control and performance evaluation purposes. Generally, multiphase induction machines are preferably modelled using the vector space decomposition technique with some assumptions to simplify the mathematical model. However, different sources of non-linearities, including low order harmonics mapped to secondary subspaces, cross-coupling saturation and iron losses result in a notable deviation from the experimentally measured waveforms. Furthermore, considering full symmetry amongst motors phases seems to be a rather idealistic assumption. Fractional order modelling has recently emerged as a promising mathematical technique to model highly nonlinear electrical and mechanical systems. This paper proposes an improved vector space decomposition (VSD)-based fractional order model of an asymmetrical six-phase induction machine under both healthy and open phase fault conditions with different neutral arrangements. The appropriate differentiation orders have been obtained by optimizing the error function between simulated and experimental waveforms. The results are compared with the conventional integral order-based model. Experimental validation has been carried out using a 1.5Hp prototype induction machine.
