Algorithm evaluation for the optimal selection of the space vector voltage using DPC in power systems

Abstract:

This work presents the experimental evaluation for a new scheme of Optimal Vector Selection (OVS) in Direct Power Control (DPC) for a three-phase rectifier without the use of switch selection tables. The OVS is physically implemented using a software configurable test rig (Platform III). Additional states were added to the standard seven space vectors obtained with a three-phase inverter bridge using Space Vector Modulation (SVM) in order to reduce the hysteresis band of the power controller. Normal operation, model parameter fit, regenerative behavior and comparisons between two different sets of vectors are analyzed.
