Fault-Tolerant Predictive Current Control with Input Reactive Power Minimization in Six-phase Generation System Driven by a Multi-Modular Matrix Converter

Multiphase generation systems are emerging as a promising technology for power generation under the distributed generation framework. These systems employ converters that present high levels of reactive power at the input, due to the switching of power switches, thus increasing losses. In this work, a strategy based on model-based predictive control using a weighted cost function is proposed to achieve the desired current and mitigate the reactive power at the input. The proposal shows a 55.72% and 29.10% reduction of THD on the generator side, without fault and when the system presents faults in module 1, respectively, which represents an improvement in power quality.
