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 the new power system configuration, the requirements, and the design criteria are reported, together with the description of the peculiarities of the new propulsion system. The activities to be carried out in order to guarantee a safe and efficient plant operation (e.g. power system simulator development) are also outlined in the final section

“…Historically, multiphase machines and drives became an attractive industrial solution in the last decades for the advantages that they can provide in terms of performance, fault tolerance and control for high power applications such as electric ship propulsion [18][19][20][21][22], wind farms [23], turbo compressors [24] and aircraft generating systems [25][26][27]. Nowadays, many efforts are being made to discover and fully exploit all the possibilities that this technology can provide.…”

In more electric aircraft (MEA) weight reduction and energy efficiency constitute the key figures. Additionally, the safety and continuity of operation of its electrical power distribution system (EPDS) is of critical importance. These sets of desired features are in disagreement with each other, because higher redundancy, needed to guarantee the safety of operation, implies additional weight. In fact, EPDS is usually divided into isolated sections, which need to be sized for the worst-case scenario. Several concepts of EPDS have been investigated, aiming at enabling the power exchange among separate sections, which allows better optimization for power and weight of the whole system. In this paper, an approach based on the widespread use of multi-port power converters for both DC/DC and DC/AC stages is proposed. System integration of these two is proposed as a multiport power conversion system (MPCS), which allows a ring power distribution while galvanic isolation is still maintained, even in fault conditions. Thus, redundancy of MEA is established by no significant weight increase. A machine design analysis shows how the segmented machine could offer superior performance to the traditional one with same weight. Simulation and experimental verifications show the system feasibility in both normal and fault operations.

“…In dc ships, only an inverter stage is required to generate the required variable voltage variable frequency output [10]. In addition to their use in propulsion and thruster drive systems, power electronics enable matching new technologies, such as modern solutions for energy storage and generation, with older technologies, such as waste heat recovery systems or conventional drives [11]- [17]. Thus, solutions can be developed for pressing problems of energy efficiency and harmful emissions onboard, concurrently with safety in navigation, cargo, and human life on sea that can be solved with the aid of power electronics.…”

This paper discusses contemporary problems concerning ship microgrids. It focuses on the role of power electronics and power quality issues, both conventional, such as voltage and frequency variations, and new issues, such as waveform distortions ensuing from the wide proliferation of power electronics in ship microgrids. The paper also contains a discussion on the provisions of the Unified Requirements of International Association of Classification Societies and other leading power quality standards in the industry, with an emphasis on Total Harmonic Distortion (THD) definition. An overview of power converters for high power applications in ships and their impact on ship networks is also given. Next, original results of various power quality phenomena recorded in ship microgrids are presented and commented on, followed by a review and recommendations for maritime microgrid modeling and signal processing methods for power quality assessment in the discussed systems. Finally, preliminary proposals for power quality control are presented.
