Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

A fault-tolerant tandem converter, based on a current-source converter and cascaded multilevel voltage-source active filter, is proposed as the grid interface for a 10MW superconducting direct-drive wind turbine generator. The converter reduces the possibility of a short-circuit fault, an issue with the extremely low generator reactance, while having a significantly lower DC capacitance requirement than an equivalent modular multilevel converter, although this is still high due to an extremely low generator frequency. Active filter DC capacitance is optimised, and a control system designed to prevent large DC voltage peaks during transients, and is verified in simulation. DC voltage balancing between the phases of the filter limits the torque control bandwidth of the converter if the capacitance is to be minimised, due to the slow speed of the balancing controller.
