CFU: 4
Prerequisites
Basic knowledge of electrical circuit and electrical machines; basic knowledge of electronics (analog and digital); basic knowledge of closed loop control systems.
Preliminary Courses
Controlli Automatici.
Fondamenti di Circuiti.
Learning Goals
The course aims at providing students with the basic approaches related to the design of both industrial automation and power systems. More in detail:
-with reference to automation systems, students are introduced to the various phases of the design process, from the elicitation of the requirements, to the test and validation of the control software by means of plant simulators. At the end of the course, the student will acquire the above mentioned basic principle as well as the programming languages for Programmable Logic Controllers (PLC);
- with reference to power systems, students are introduced to both the features of the technological components and the design methodologies for industrial power systems.
Expected Learning Outcomes
Knowledge and understanding
The course provides students with the technological characteristics of electrical components and the methodologies for their integration in medium and low voltage power systems. Former, the components are discussed in terms of electrical features; later the typical methodologies for correctly integrating the components in distribution power systems are examined with special regards to security and electrical safety. Students needs to show both knowledge of component features and understanding of power system design criteria.
Applying knowledge and understanding
Student needs to be able to analyze data on energy requirements, for solving problems of designing power systems in industrial context by using methodological tools for medium and low voltage systems. Students needs to carry out simple projects coupling electrical components for satisfy load power requirements.

Teaching Methods
The teaching is carried out with lectures (70% of total hours) and laboratory exercises (30% of total hours).
Examination/Evaluation criteria
Exam type
The module of Sistemi Elettrici Industriali includes a final oral test. The exam aims to verify the capability of the student to discuss on supplying electrical loads and electrical safety, focusing on features of technological components and methodologies for designing power systems. Solving a numerical exercise can be required. Student has to highlight the understanding of all the course’s topics
Evaluation pattern
The final mark is weighted with respect to the CFU of each module as follows:
- Module Tecnologie dei sistemi di automazione e controllo, 8 CFU, 67%
- Module Sistemi elettrici industriali, 4 CFU, 33%
The written exam performance is binding to have access to the oral exam. Both the written and the oral exams contribute 50% each to the final mark. Therefore passing the written exam is only a necessary condition to pass the overall exam.
