Modalità di insegnamento
Frontal lessons, laboratory and exercises

Obiettivi formativi
Learning Outcomes: (1) Knowledge and understanding: The Hydro Power module provides the knowledge for run-of-the-river (RoR) hydro power plant analysis and design. The frontal lessons and laboratory exercises will give the necessary in-depth analysis of hydraulic design of each component of a RoR Hydro Power Plant (and assistance to design during laboratory hours). Wind energy course provides the basic knowledge for wind energy systems analysis and design. Main technical, and economical aspects for the proper selection and design will be faced and discussed. Small wind turbines application area and large wind farm design will be developed through two dedicated projects. (2) Applying Knowledge and understanding: During one or two visits to large and/or mini hydro power plants (scheduled during the course), the elements which compose the hydroelectric system will be analyzed and understood, through practical examples. The wind power course makes use of lectures, with introduction and discussion of the general aspects of wind turbine design, project assignment, work in laboratory with commercial codes and group meetings to review the progress of the projects assigned. (3) Making judgments: Students will be able to analyze and evaluate the potential performances of an HPP. Students will acquire the ability to analyze technical and economic feasibility of small wind projects and large wind farm projects. (4) Communication skills: Students will improve their communication skills by learning how to write and discuss a technical auditing report after a visit to a plan (5) Learning skills Student will learn (second part of the “Hydropower systems” module) to develop in detail the hydraulic design of each compartment constituting a mini hydro power plant, including: weir, intakes, settling basin, head race, surge tank/forebay, penstock. The course will transfer knowledge and methods for the design of small wind turbines and wind farms. The draft design of a wind farm will be developed. Two visits will be organized.

Modalità d'esame
Oral exams and exercises/report. - Formative assessment: Report: during the course; ILOs assessed: (2), (3), (5). - Summative assessment: 100% oral examination, including presentation and discussion of the report: about 1 hour; ILOs assessed: all except (5).

Criteri di valutazione
The exam of hydro power module and of wind power module consists of oral presentation and discussion of the projects and deliverables of the individual working groups, with the identification and evaluation of the contributions of individual participants.
