Geração de energia a bordo: excitação de geradores e análise de caso sobre blackout

Abstract

The on-board power generation system is undoubtedly one of the most essential components of a vessel, and its importance is growing with the expansion of automation and the popularization of diesel-electric propulsion. However, the training and education of engineer officers did not follow this change satisfactorily, and although most competent engineers are capable of dealing with failures and maintenance of generator sets, there is a general lack of knowledge concerning deeper aspects of its functioning. In this work, after a brief review of generator systems in general, we will delve into an essential component for electrical generation: the excitatory-voltage regulator set, which enable the starting of the voltage pick-up. After this, we will conclude by using a real example of blackout, in which both the cause and the delay in completing the investigation regarding the occurrence were caused by the lack of instruction regarding this particular aspect
