In this paper modelling and analysis of stand-alone dual stator induction generator (DSIG) with non-identical parameters under a new method has been done. The induction machine has two sets of stator three-phase windings spatially shifted by 30 electrical degrees. One supplied power to the DC load via a rectifier bridge and AC capacitors, and the other was connected to the battery banks by an inverter to store energy and restore it to regulate the power of the first stator in weak wind. We develop the steady state model and show the performances of different configurations by the simulation results.

“…It starts from the overall effect of three-phase output voltage and focuses on how to make the motor obtain the ideal circular flux linkage [9], [10]. Compared with SPWM, the SVPWM technology has a small harmonic component of the winding current waveform, which reduces the torque ripple of the motor, and the rotating magnetic field is closer to a circular shape [11]. Moreover, the utilization of the DC bus voltage is greatly improved, and it is easier to digitize [12], [13].…”

A Novel Method Simulating Human Eye Recognition for Sector Judgement of SVPWM Algorithm

The conventional space vector pulse width modulation (SVPWM) algorithm is mature and widely used in the control of three-phase inverters. As we know, the position of the voltage vectors can be seen directly by human eyes, which can be used to replace the existing way for sector selection in the conventional SVPWM algorithm. Based on the fact, a novel method simulating human eye recognition for sector selection of SVPWM is proposed in this paper. In the real application, machine can replace human eyes, and it can 'see' the sector step by step in which the voltage vector is located, and immediately give the switching time of the two non-zero voltage vectors. Theoretically, it can save the running time and complexity of the SVPWM algorithm reflected in the situation that multiple inverters are connected in parallel with the number of voltage vectors being increased. The feasibility of the proposed SVPWM algorithm has been validated by both simulation and experiments, which offers the possibility of the application in the multiple or multilevel converters. INDEX TERMS SVPWM, machine vision, voltage vector, multiple inverters.

“…Space vector pulse width modulation (SVPWM) is the main modulation method of electric machine control. At present, various SVPWM methods for six-phase system are mainly focusing on the performance indicators such as current, flux, torque and speed [16][17][18][19]. However, how to effectively suppress the magnitude and frequency of CMV and simultaneously achieve these performance indicators needs further investigation.…”

There are two common-mode voltages (CMVs) in a six-phase machine with two Y-connected windings shifted by 30°, which bring adverse effects on the six-phase system. In this study, a method of six-phase space vector pulse width modulation (SVPWM) is proposed, which can suppress the magnitude and frequency of the two CMVs. First, all basic vectors are divided into 16 classes, from which two classes of basic vectors are selected. With these two classes of basic vectors, some auxiliary vectors are constructed according to an optimisation model. Then a reference vector is synthesised by using these auxiliary vectors. There are two kinds of synthesis schemes, single-class synthesis and two-class synthesis. Finally, optimal sequences of the basic vectors that play a role in each switching period are obtained. The experimental results show that the peak-to-valley value of CMV is only one-third of the DC-bus voltage of the converter in the two-class synthesis, and the frequency of CMV is only three times of the line voltage fundamental frequency, which is far below the switching frequency of the converter.
