In this paper, a demonstrative technological implementation of a shipboard 2.15-MVA generation system is described, along with its modeling, numeric simulation, and some factory tests. The system, named Naval Package (NP), is part of a demonstrative program commissioned by Italian Navy for preliminary evaluations of medium-voltage dc supply technologies(More)
Italian Navy is being equipping its fleet with the new FREMM class of frigates, developed under a joint program by Italian and French Navies. They are conceptually new war ships endowed with a hybrid propulsion system, composed by a gas turbine and two electric drives, which can be operated also as shaft-generators. University of Trieste has been charged(More)
This article reports on the design, development, and validation of advanced prototype 2 MVA generation equipment [i.e., naval package (NP)] for a shipboard medium-voltage dc integrated power system (MVDC IPS). The generation equipment is based on an ultrahigh-speed 22,500-r/min 12-phase alternator, which feeds an ac/dc power electronics converter comprising(More)
This work proposes a novel fault diagnostic technique for photovoltaic systems based on Artificial Neural Networks (ANN). For a given set of working conditions solar irradiance and photovoltaic (PV) module's temperature a number of attributes such as current, voltage, and number of peaks in the current evoltage (IeV) characteristics of the PV strings are(More)
RTAI extension to Linux operating system makes it possible to perform Hard Real-Time (HRT) controls using a commercial PC and utilizing open-source code. This paper details a software installation process, along with the suitable hardware chosen for realizing motion controls using Linux-RTAI. Advantages offered by the possibility of designing and developing(More)
A major limitation to the development of feedback acceleration controls in motion servo drives is the difficulty of detecting angular acceleration. This paper presents an innovative method for determining angular acceleration in servo-drives for industrial applications. The proposed method detects angular acceleration through the processing of the output(More)
The paper points out innovative design issues of the shipboard power stations for all electric ships (AESs). Alternators and voltage control system operations are reviewed under an approach which emphasizes the impact of design choices on power generation and availability. The work moves from an in-deep analysis of modern cruise ship integrated electric(More)
The training tall ship Amerigo Vespucci is the masterpiece of the Italian Navy fleet. Counting about 80 years of service, its refitting was mandatory, due to severe critical issues in efficiency, sustainability, logistic management and operation safety. Taking advantage of the full renewal, an innovative propulsion system has been designed. In this paper(More)
