CODE 66118 ACADEMIC YEAR 2018/2019 CREDITS 6 cfu anno 3 INGEGNERIA NAVALE 8722 (L-9) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/33 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 2° Semester TEACHING MATERIALS AULAWEB OVERVIEW The teaching of naval electrical systems aims to consolidate the skills of the naval engineers students in an application context of the knowledge of electrical engineering. Training proposals are proposed on the sizing methods of the on-board electrical system, proceeding from the definition of the most appropriate configuration in compliance with the normative dictates to the study of the electrical balance and concluding with the choice of protection devices. AIMS AND CONTENT LEARNING OUTCOMES The design principles of the on-board electrical systems are illustrated, with particular attention to the choice of the scheme, the voltage levels, cable sizing and the choice of protection systems. AIMS AND LEARNING OUTCOMES The aim of the course is to introduce the student to the basic problems related to the operation and design of the electrical systems on board. The object of the study consists of a representation of the main components of the electrical systems and their sizing with specific reference to the naval sector. TEACHING METHODS Theoretical lessons and exercise (5 hours per week) SYLLABUS/CONTENT Introduction Concept of electrical power system Laws and standards in civil application Standard for military sector Generation and electric conversion Primary electrical sources Synchronous machine operation in steady state and under transient Active and reactive power exchange Per unit (p.u.) notation Energy conversion Control systems Voltage regulation Frequency regulation Power system distribution Overall consideration Typical schema for civil and military (radial, loop,zonal) Overcurrents: evaluation and protection Generalities Overcurrent protections Short-circuit calculation (methods) Breakers and fuses characteristics Short-circuit protection Protection coordination Energy end-use Overall description Lights Electric drives Electric propulsion Overall description Conventional and electrical propulsion Hybrid propulsion Elements of electric safety Electric current effects Direct and indirect contacts Protection for direct and indirect contacts TEACHERS AND EXAM BOARD FEDERICO SILVESTRO Ricevimento: Prof. Federico Silvestro By appointment arranged through email or phone. tel. 0103532723 email: federico.silvestro@unige.it MARCO INVERNIZZI Ricevimento: By appointment arranged through email or phone.
