“…The main limitation of this method is assumption of linear material relations in time-harmonic analytical model, which would inevitably deteriorate simulation accuracy. In [114], Chen et al presented a so-called virtual blocked rotor technique for simulation of induction machines. In this method, the "virtual blocked rotor" technique in frequency-domain analysis provides an approximation of initial conditions including initial permeabilities and rotor bar currents for FEA transient analysis performed in the time domain.…”

“…However, FEA models are timeconsuming due to significant computational burden associated with finite-element (FE) calculations. For induction machines, including SCIMs, WRIMs, and DFIMs, as aforementioned in Section III, there is a lengthy FIGURE 19 Reducing transient response time in FEA simulation of induction machines [114] numerical transient response time during run-up towards a steady state in time-stepping FEA simulation. This lengthy transient response time usually involves use of prodigious amounts of computer resources.…”

With ever-increasing concerns on energy crisis and environmental protection, there is a fast-growing interest in wind power generation systems. As electric machines and drives are core components in wind turbines, it is a pressing need for researchers and engineers to develop advanced electric machines and drives for wind power generation. This paper provides a thorough review of modern electric machines and drives for wind power generation, with emphasis on machine topologies, operation principles, performance characteristics, as well as control strategies. The key features of electric machines and drives including their merits and demerits, e.g. torque/power density, efficiency, and cost, are compared and summarised. Trade-offs involved in various presented methods and strategies are highlighted. The major challenges and difficulties, which electric machines and drives for wind power generation are facing, are discussed. Moreover, the developing trends and opportunities are revealed, while the latest development is also discussed.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Conventional IMs are often modelled using a timeharmonic field approximation using the complex magnetic vector potential [15] with the non-linearity of the magnetisation characteristic represented by a time-averaged effective characteristic [18][19][20][21][22]. The analysis is carried out for the fixed rotor geometry and enables the determination of machine characteristics at arbitrary conditions without the need to recall the equivalent circuit model.…”

A computationally efficient time-harmonic finite element model for the steady-state analysis of a brushless doubly fed induction machine (BDFIM) is proposed. In the model, the electromagnetic couplings of the BDFIM are described by means of the sum of two complex magnetic vector potentials that represent the two fundamental harmonic time components of the magnetic flux density distribution in the rotor frame of reference. As in an ordinary induction motor, the non-linearity of the magnetisation characteristic is accounted for using an effective magnetic permeability. For the BDFIM, this is derived by considering the features of modulated magnetic flux density waveform. The accuracy of the approach has been validated by comparing the characteristics of a D270 machine operating in the double-feed mode with ones obtained from the experimentally verified time-stepping model at various operating conditions. High accuracy of the results coming from the proposed model is demonstrated even under deep saturation conditions within the magnetic circuit.

This work shows the results obtained from studying the influence of equivalent circuit resistances on three-phase induction motors. The stator resistance, rotor resistance, and iron losses resistance affect the different motor operating variables (output power, current, speed, power factor, starting ratios, and maximum torque). These influences have been quantified, paying particular attention to the losses affected and their impact on efficiency. The study carried out does not apply optimization techniques. It evaluates the different influences of the equivalent circuit’s different resistances on its operation by evaluating applicable constructive modifications concerning available motors. The work has been limited to three-phase induction motors up to 50 kW and low voltage, with the nominal powers of the selected motors being 0.25 kW, 1.5 kW, 7.5 kW, 22 kW, and 45 kW. The tools used to carry out the study are analyzing the equivalent circuit and the simulation of the electromagnetic structure using a finite-element program. The variations proposed in each resistance for all the motors studied is not purely theoretical, as it is based on applying feasible constructive modifications, appropriately analyzed and simulated. These modifications are the variation of the conductor diameter in the stator coils, the change of the section of the rotor cage, and the selection of different ferromagnetic steel types.
