This paper presents a novel dynamic model of a matrix converter (MC) that utilizes a space vector modulation (SVM) switching method. The MC is intended as the interface medium between a distributed resource (DR) unit, e.g., a microturbine-generator, and the utility grid. The MC model is developed in the direct-and quadrature-axis reference frame to be consistent with the utility grid model for dynamic studies. The model can be used for investigation of large signal transients as well as small signal dynamics. The accuracy of the model is validated by comparing the study results obtained from the developed model with those from the exact switched-model of the MC in the PSCAD/EMTDC environment.Index Terms-dq reference frame, dynamic model, matrix converter, space vector modulation.

“…The MC eliminates the DC link components and inherently resolves the size, weight and reliability issues and also provides an option for design/fabrication of the converter as a compact/modular unit. [18], the application of the MC as the interface converter for a high-speed MTG unit, where a high input to output frequency ratio is involved, has not been reported. This paper introduces a new switching strategy and a control approach tailored for the MC as the interface between a high-speed MTG unit (2221 Hz voltage frequency) and the utility grid (60 Hz).…”

This paper investigates the use of an AC-AC matrix converter, as an alternative to AC-DC-AC converter system, to interface a high-speed micro-turbine generator (MTG) to a utility grid as a distributed generation unit. A new switching strategy and a control mechanism for the converter are presented. Based on time-domain simulations in the PSCAD/EMTDC environment, the dynamic behavior of a micro-turbine generation system, including the dynamic models of the micro-turbine (thermodynamics), generator, matrix converter, converter control and micro-turbine control, is studied. The studies conclude that a matrix converter is technically a viable option to interface a MTG to a utility grid.
