•Knowledge and understanding
In-depth knowledge and comprehension of theoretical and modelling aspects of High Voltage power systems
•Applying knowledge and understanding
Ability to analyse the steady state behaviour and control of electricity transmission grids
Ability to assess the correct management of a High Voltage power system
Potential to engage technical discussions on planning and operation of High Voltage power systems
Propensity to continuous learning, through the correct understanding of the scientific Literature
Compulsory pre-requisites are indicated in the rulebook of the Electrical Engineering Master degree.
In any case, in order to deal profitably with the contents of the course, it is:
- useful to be informed in Power Electronics,
- important to know the general principles of physics and, particularly, of electromagnetism, and
- essential to have knowledge of Electric Circuits and of Electrical Power Systems.
The course has the goal of introducing the study of High Voltage electrical power systems, by describing firstly their essential characteristics and the main components and, successively, by analysing the steady state operation of the electrical power transmission grids. In particular, the following topics will be studied:
- transmission lines and HV substations;
- performance of lines (propagation laws, particular cases of line operation, equivalent models of lines);
- the load flow problem;
- high voltage DC transmission;
- frequency regulation;
- voltage regulation;
- general principles of Power Systems reliability.
45 hours of frontal lectures, by using the blackboard and multimedia devices, and 15 hours of practices, by using power system simulation softwares.
Verification of learning
The assessment of the learning level achieved by the student occurs with a written examination plus an oral colloquium.
The written examination performed at the end of the course or as first examination test has the goal to verify the application ability of the steady state models and calculation techniques for the analysis of the electrical power transmission grids. The examination is formed by theoretical and practical exercises on the transmission line performance, the load flow calculation, and the HVDC transmission systems. A positive overcome of the written examination requires an adequate knowledge of the models used for the steady state representation of the main components of the High Voltage power system. Any “educational debt” in the written examination (for no more than the 50% of the exercises proposed) will have to be compensated during the oral colloquium.
The oral examination aims at highlighting the level of skills and knowledge matured on the complex operation of the High Voltage electrical power systems; indeed, the correlations and multi-objective problems that characterise the operation of complex systems are arguments well structured for assessing both the level of knowledge acquired and the ability to engage technical discussions on the High Voltage power system management and control.
In order to help the self-assessment of the students, in-class tutorials are performed during the course for simulating the written examination.

Slides of the frontal lectures, other didactic material, software with student license and related user guides are provided to the students during the course.
The student workers or those students that cannot follow assiduously for manifest reasons (e.g. students with small children) can perform on-line tutorials and tests on specific arguments with the support of the professor or of a designed tutor by using Microsoft Teams platform.
