Learning outcomes
At the end of the course the student will own skills regarding the structure and analysis of the operation of MV and LV electrical systems and of the main components: overhead and cable lines, stations, short circuits calculation and interruption methods, manouvre and protection devices. At the end of the course, the student will also own skills regarding electrical safety and the main design criteria of electrical systems of LV and MV users.
Course contents
As the course is delivered in Italian, the reader is encouraged to refer also to the corresponding box written in Italian. For convenience, however, the relevant translation in English is provided below.
The course is divided into two modules pf 60 and 30 hours respectively both delivered by Prof. C.A. Nucci: in the 60 hours of lecture the principles, the structure of the electrical systems, as well as the theoretical basis for their design and the connection to them of renewable source generators is provided; the module of 30 hours is devoted to examples and exercises on the design of electrical systems of medium and low voltage (MV and LV) and to Renewable Energy Communities.
The course program is as follows:
- History of electrical power systems (elements of)
- National electric energy needs and Structure of transmission and distribution networks
- Transmission line theory: primary and secondary parameter, wave equations, equivalent circuits, appraisal of voltage drops
- Transformers and synchronous generators (brief survey on fundamentals)
- Load-Flow basics
- Sequence method for the solution of unbalanced three-phase systems
- Thermal analysis of operation conditions of overhead lines and cables and Joule integral
- Electro-dynamic effects of short circuit currents
- Electric arc theory
- Switch-gears, control-gears, and protection devices for medium voltage (MV) and low voltage (LV) levels
- Electrical safety in electrical installations: electric shock safety curves (current and voltage), protection against direct and indirect electric contact
- Neutral conductor earthing methods
- Lightning protection of lines and structures
- Emergency Power Systems Units and UPS
- Smart grid and climate neutral smart cities
- Local Energy Communities (CEC and REC)
- Design and sizing of electrical LV and MV plants and their connection to the grid, with particular reference to dispersed/renewable generation, layout definition, sizing of electrical ducts/lines, short circuit calculation, protections selection and relevant coordination, power factor correction systems, relevant standards.
- Elements of lightning technology
Readings/Bibliography
As the course is delivered in Italian, the reader is encouraged to refer also to the corresponding box written in Italian. For convenience, however, the relevant translation in English is provided below.
- Copies of the slides illustrated during the course are provided to students before each relevant lecture; written notes prepared by the docents of the Electric Power Systems laboratory of the University of Bologna are provided to students too.
Teaching methods
As the course is delivered in Italian, the reader is encouraged to refer also to the corresponding box written in Italian. For convenience, however, the relevant translation in English is provided below.
- Traditional frontal lectures with the help of ppt slides and blackboard.
- Exercises on the blackboard.
- Laboratory exercises with the aid of the computer for the calculation and sizing of electrical systems.
- Laboratory sessions on MV and LV equipment.
Assessment methods
As the course is delivered in Italian, the reader is encouraged to refer also to the corresponding box written in Italian. For convenience, however, the relevant translation in English is provided below.
For 6 CFU Module an oral test is required to be successfully accomplished. To this aim, students must demonstrate solid preparation concerning the main concepts discussed in the lectures and in particular in relation to the theoretical basis, the methods of calculation and assessment of the equipment and the operating principles used. A higher score will be awarded to students who demonstrate that they understand and are able to apply all the methodological content by exposing them with mastery. The test is failed when the insufficient knowledge of the main concepts of matter and of the technical language are evident from their oral exposition.
For Module 3 CFU it is necessary to pass a written test regarding the design and sizing of an electrical system of MV/LV in which the presence of generation from renewable sources is expected to be included.
