AIMS AND LEARNING OUTCOMES

The aim of the course is to introduce the student to the main aspects related to the operation of electric propulsion and generation systems on board electric ships, to guide him in understanding the technologies and the main electrical system problems.

The use of electric propulsion is the current standard for different types of ships. The field of use of variable speed electric motors is wide and provides for various reliable and economically competitive construction solutions. The resulting degree of electrification is total and determines the creation of integrated and automated generation systems, capable of providing all the power required by the ship.

The course introduces the methodological and technological aspects related to the design of on-board electrical systems and related control systems, through the development of mathematical and circuit models, privileging applicative and systemic aspects.

PREREQUISITES

There are no specific requirements.

TEACHING METHODS

The course is held with lessons and exercise based on different Matlab toolboxes for an overall amount of 60 hours.

Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's disability liaison at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns.

EXAMS

EXAM DESCRIPTION

The exam is divided into an exercise and an oral exam.

The learning assessment involves the development of an exercise consisting of the development of a computer model on the topics specified in the specific training objectives to be delivered one week before the oral exam. The admission judgment allows you to take the oral exam, which lasts approximately 45 hours.

Students with disabilities or with DSA can request compensatory/dispensatory measures for the exam. The methods will be defined on a case-by-case basis together with the Engineering Representative of the University Committee for the support of disabled students and with DSA. Students who wish to request this are invited to contact the course teacher well in advance, copying the Engineering Representative (https://unige.it/commissioni/comitatoperlinclusionedeglistudenticondisabilita.html), without sending documents regarding their disability.

ASSESSMENT METHODS

Verification of acquisition of theoretical and practical knowledge of calculation methodologies typically used for the design and operation of naval electrical systems and naval electric propulsion. The exercise will assess the student's ability to solve numerical exercises on the computer and the ability to model electrical systems and related controls. The oral exam will allow to verify the student's ability to propose and argue about theoretical and applicative methods concerning naval electrical systems and naval electric propulsion drives. The quality of the presentation and the correct use of specialized vocabulary, the ability and autonomy of reasoning, the correct use of units of measurement and the recall of the previously defined cultural prerequisites will also be assessed.
