A control strategy for a three-level unified power quality conditioner
| Resumo: | In this work a control strategy for a three-level Unified Power Quality Conditioner (UPQC) is introduced. Basically, this control strategy is based on the set of active and non-active (reactive) power definitions in the time domain, which have been proposed by Fryze in the 30´s of the last century. The goal of this work consists in expand this control strategy to deal with three-level converters. The use of three-level converters allows a better performance of the equipment, by reducing harmonics and the ripple of the generated voltages and currents. Simulation results on PSCAD/EMTDC will be illustrated in order to verify the accuracy of the expanded control strategy. |
