Análise da estabilidade de inversores conectados em paralelo em rede isolada, sem interconexão no controle e com aumento do amortecimento via malha de deslocamento de fase
Abstract:This work presents the small signal stability of sinusoidal PWM inverters connected in parallel in a standalone system, that is, without the presence of an infinite bus. The inverters have no interconnection control, so that only local variables are referred. The control strategy of each inverter unit is based on the Pxω and QxV droops and it has an additional loop δxP designed to increase the damping. This loop feeds the deviation of the active power of inverter from its nominal value back into the reference … Show more
