All Electric Ship power stations: Dynamic coordination between controls and protections

Subject of this paper is dynamic coordination of power station controls and protections in All Electric Ships (AESs). The aim is to promote an integrated approach to the design of control systems and protections, which are involved in the overall management of the station and therefore have a relevant impact on power generation, quality and safety. Normally, the design of alternators, AVRs and protections is demanded to different subjects, who often do not share information. This prevents from performing a systematic analysis of transient phenomena and can lead, in critical cases, to a wrong dynamic operation of the system, with possible heavy consequences. This work aims at improving dynamic coordination between AESs power stations protections and controls.
