Reducción del desequilibrio de voltaje mediante el uso del interruptor de transferencia estática, en una micro-red

Abstract

In this article, the model of an unbalanced bipolar micro-network in direct current is proposed. The results of a set of maneuvers are presented which aims to reduce voltage unbalance and therefore minimize power losses using static transfer switches STS. For the development of this article, the simulation of the original micro-grid without distributed generation DG and the micro-grid with DG was taken into account. All study cases were simulated in the ATP Draw software. In both cases, the voltage unbalance is analyzed with and without the use of the switches, in the furthest node of the micro-network to observe the voltage difference between them. The results obtained in this article were achieved with the correct location of the switches STS, the reduction of power losses, voltage imbalance, complying with the limit range of the percentage of imbalance %VU between lines and therefore reducing the drop. voltage on each line.
