Power system module: the students will acquire the knowledge on the structure of the electrical system. The students will be able to handle the fundamental variables of the electrical system (voltage, current and power, both active and reactive), recognize the main components of the electrical system (lines, transformers, and protection devices), and evaluating the performance of the last-mile electrical chain (transformer, line and load), also in the presence of power factor correction and distributed energy resources. Power electronic converters and electrical drives: the students will be able to understand the presence of power electronic converters in a grid and the use of power electronic converter in moder smart grids

Complex numbers. Fundamentals of electrical circuits. Fundamentals of magnetic circuits. Basic course in electrical engineering (ability to analyse dc and industrial frequency ac networks).

Power system module: Structure of the power system: production, transport, distribution and utilization. Voltage levels in the power system. Modeling of the electrical lines: PI-model and its simplification according to the voltage level. Voltage drop and power factor correction. Efficiency of the line. Structure and principle of operation of single-phase and three-phase transformers. Open-circuit and short-circuit test on the transformer. Equivalent circuit. Efficiency of the transformer. Short circuit currents (three phase, single-phase, phase-to-phase faults). Circuit-breakers in High Voltage, Medium Voltage and Low Voltage circuits. Basic of electrical safety. Examples of applications. Visit to one of the MV/LV substations of Politecnico di Torino. The students will have the possibility to see all the components described during the lecture in a real layout, which will be helpful in the subject understanding. Power electronic converters and electrical drives: Basic concepts related to automatic controls. Introduction to power electronic conversion. Power electronic devices and basic topologies for power electronics converters. Losse in power electronics devices. Description and analysis of power electronic converter employed in power conversion with electromechanical actuators, photovoltaic plants, islanded or connected smart grids.

The course is composed of theoretical lessons (48h), exercises and visit to laboratories (12h).

Lecture slides;

Exam: Compulsory oral exam;

Two separate oral exams, one for the Power system module (30 min.) and one for the Power electronic converters and electrical drives module (30 min.) are planned at the end of the course. The final evaluation will be defined by the averaged evaluations of the two oral exams. The oral examinations aim at assessing the knowledge of the topics discussed during the course and the ability of the student to analyse and discuss about the topic of the course.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
