“…However, three nonconventional solutions for voltage control of variable-speed induction generators were proposed in [16,20,21]. The multiphase induction and synchronous generators can produce the output voltage at broken phase connections tolerating the machine or converter damages [17,22,23].…”

The subject of this publication is a method of controlling the DC voltage of a PWM rectifier supplied by a multiphase cage induction generator with the number of stator phases greater than three operating in a wide range of driving speeds. Voltage regulation is performed by changing the frequency and amplitude of the stator voltages with simultaneous switching of the phase sequence of these voltages. The step change of the voltage sequence is made in the designated ranges of the generator speed, which enables the stabilization of the output voltage in a wide range from the minimum speed of about 25% of the rated speed. Such sequence switching changes the number of pole pairs produced by the winding for each supply sequence. The difference compared to multi-speed induction machines is that, in the presented solution, there is only one winding, not a few, which enables good use of the machine’s magnetic core in the same dimensions as for the three-phase machine of a similar power. Steady-state characteristics and dynamic operation were obtained using laboratory measurements of a standalone nine-phase induction generator. The automatic control system maintained the output voltage at the set level, regardless of the generator load and driving power.

“…Multiphase induction machines with the second type of winding can practically work at the supply sequence number m = 1. Such a machine can be designed with almost sinusoidally distributed windings, having all the advantages of fault tolerance of multiphase induction machines [4,17,22,23,25,26].…”

“…A proposed idea of a passive or natural fault tolerance has been presented in [10][11][12][13]. It is demonstrated that it is possible to develop a drive control algorithm which should not be re-configured after a fault occurs (i.e., the current reference values will be automatically adjusted in the post-fault operation mode).…”

Applicability Analysis of Indices-Based Fault Detection Technique of Six-Phase Induction Motor

et al. 2021

The multiphase induction motor is considered to be the promising alternative to the conventional three-phase induction motor, especially in safety-critical applications because of its inherent fault-tolerant feature. Therefore, the attention of many researchers has been paid to develop different techniques for detecting various fault types of multiphase induction motors, to securely switch the control mode of the multiphase drive system to its post-fault operation mode. Therefore, several fault detection methods have been researched and adapted; one of these methods is the indices-based fault detection technique. This technique was firstly introduced to detect open-phase fault of multiphase induction motors. The main advantage of this technique is that its mathematical formulation is straightforward and can easily be understood and implemented. In this paper, the study of the indices-based fault detection technique has been extended to test its applicability in detecting some other stator and rotor fault types of multiphase induction motors, namely, open-phase, open-switch, bad connection and broken rotor bar faults. Experimental and simulation validations of this technique are also introduced using a 1 kW prototype symmetrical six-phase induction motor.

“…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: High Reliability: The reliability of the generator should be high. With the help of a reliable DFIG system, the interruption due to fault can be mitigated. Fast response: The response of the machine should be as fast as possible by keeping minimum plant down time. Lower pulsating torque: The pulsating torque of DFIG should have as lower as possible during six step inverters feeding. …”

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.
