Special Issue Information

Dear Colleagues,

With the future requirement of reducing CO2 emissions and therefore producing more and more electrical energy, AC generators will undergo ever-increasing development. To meet this challenge of producing continuously increasing quantities of electrical energy, the new generator types, whether they are low or high power, will have to ensure continuity of service by being ever more fault-tolerant.

A suitable solution to increase the reliability of a generator is to use a multiphase machine with symmetrical or asymmetrical structure. Indeed, with this configuration, an electrical fault on the machine or on the converter does not induce the shutdown of the electrical energy production, since three phases are remaining; this lies in contrast to classical solutions designed around three-phase machines.

Nevertheless, in this fault mode, due to the unbalances between the stator and rotor sides, the quality of the produced energy can be significantly impacted in terms of harmonics, as an example.

Therefore, advanced control strategies must be applied to multiphase machines to cope with this unwanted behavior during fault mode.

This Special Issue focuses on the development of fault-tolerant advanced control strategies for multiphase induction generators, whether they are low or high power.

Contributions may concern, for example, self-tuning, intelligent control, fuzzy control, sliding mode control, or predictive control techniques, among others. Particular attention will be paid to the experimental applications of the proposed control techniques.

A common-mode voltage (CMV) suppression strategy, namely double zero-sequence injection common-mode voltage (DZICMV), is proposed in this paper for an asymmetrical six-phase induction motor fed by two-level dual three-phase voltage source inverters (VSIs). In this strategy, the sinusoidal waveforms injected by double zero-sequence signals are employed as modulation signals, and two opposite triangular waveforms are used as carriers. The fundamental period is divided into 24 sectors. In each sector, the carrier used by the medium amplitude phase is distinct from the carriers used by the other two phases in each set of three-phase windings. Using this method, the zero vectors (000) and (111) in each set of three-phase windings can be eliminated, and the peak values of sub-CMV and total CMV can be reduced from ±Udc/2 to ±Udc/6. The experiment results show that the root mean square (RMS) value of common-mode leakage current in DZICMV can be reduced by 51.83% compared with the double zero-sequence injection PWM (DZIPWM) strategy. It is also found in the other four existing benchmark CMV suppression strategies that the peak values of sub-CMV therein are nearly all ±Udc/2, and only in the low linear modulation region could one of these strategies suppress sub-CMV peak values to ±Udc/6. However, the proposed DZICMV can suppress the sub-CMV peak values to ±Udc/6 in the whole linear modulation range. Moreover, the maximum linear modulation index of the DZICMV is 1.15, which is larger than that of the four benchmark strategies, whose maximum modulation index is 1. Full article
