“…As shown in Table 2, SB fault-detection methods have been widely carried out using vector space decomposition (VSD) components [15,18,44,[53][54][55][56][57][58][59][60][61][62][71][72][73][74][75], although monitoring just the phase currents has also been suggested for this purpose [48][49][50][51][52][67][68][69][70], especially in older papers. In a 2012 publication [48], Meinguet et al propose the localization of open-phase faults by quantifying the imbalance of the phase currents, exploiting the fact that these signals are more affected by the occurrence of a fault than the main (α 1 -β 1 ) VSD subspace.…”

“…However, R2 is not fulfilled either. Although phase currents can exhibit these limitations when monitored, Wen et al recently proposed in [52] a fault-detection method based on them for identifying the sector affected by an OC fault, in a three-sector nine-phase PMSM. The alarm is set when the instantaneous (not average) absolute value of a phase current is lower than a threshold while the current error of said phase (with respect to its control reference) is large.…”

“…Furthermore, if the OC situation emerges as a consequence of the detection and tolerant procedure of other faults (see Figure 1), as discussed in Part 1, then the diagnosis of the OC is not necessary either. Nonetheless, tolerance to OCs based on OC-fault diagnosis and adequate reconfiguration is still common in current multiphase drives, as shown by the fact that most of these detection methods were proposed during the last five years [15,18,[44][45][46][47][50][51][52][54][55][56][57][58][59][60][61][62][71][72][73][74][75].…”

“…The main characteristics of the existing detection approaches for phase/switch OC faults in multiphase drives are summarized in Table 2. From this table, it can be observed that some MB [43][44][45][46][63][64][65] and KB [45][46][47]66] solutions for OC identification are available, even though SB ones [15,18,44,[48][49][50][51][52][53][54][55][56][57][58][59][60][61][62]65,[67][68][69][70][71][72][73][74][75] are the most popular by far.…”

A Comprehensive Survey on Fault Tolerance in Multiphase AC Drives, Part 2: Phase and Switch Open-Circuit Faults

Multiphase machines are very convenient for applications that require high reliability. In this two-part survey, the state of the art about fault tolerance in multiphase drives is reviewed. In Part 1, an overview including numerous fault types was presented, along with fundamental notions about multiphase drives. Here, in Part 2, the focus is placed on phase/switch open-circuit (OC) faults in particular, which have received the most attention in the literature. Phase OC failures involve OCs in stator phases or in converter-machine connections, and switch/diode OCs are frequently dealt with similarly or identically. Thanks to the phase redundancy of multiphase drives, their operation can be satisfactorily continued under a certain number of OCs. Nonetheless, the procedure to follow for this purpose is far from unique. For given OC fault conditions, numerous fault-tolerant possibilities can be found in the literature, each of them with different advantages and disadvantages. Moreover, a great variety of methods have also been devised to detect and diagnose phase/switch OC failures so that, as soon as possible, the most appropriate fault-tolerance measures are applied. Thus, given the broad literature about tolerance to phase/switch OC faults in multiphase drives, the survey presented here is expected to be of great interest for the research community and industry.

“…Since the main objective of this paper is to investigate the postfault reconfiguration and the associated control for the APGC, regarding the fault detection, this paper did not propose a new method. The open-circuit fault detection method proposed in [32] is adopted because it is simple for implementation, fast and accurate for detection, and needless for extra sensors.…”

This paper presents a control scheme for a recently reported aircraft advanced power generation center (APGC) during postfault operation conditions. Within the APGC, two electrical generators extract power from two separate engine shafts and supply electrical power to a common HVDC bus through their dedicated main AC/DC power converters. An extra back-to-back (BTB) converter is also used to connect the ac terminals of the two generators. This architecture provides merits of fault tolerance capabilities of the APGC. In the case of main AC/DC power converter failure, the system can be reconfigured and the BTB converter provides an extra power flow path from the generators to the HVDC bus. This ensures electrical power generation capabilities onboard. The paper discusses in detail the control of the APGC under fault conditions with one main AC/DC converter failure. A seamless transition scheme from normal operation to postfault conditions is proposed using a voltage command initialization technique within the BTB converter. Both experimental and simulation results have verified the fault tolerance improvement and control performances of the APGC.
