Electric Engineering Fundamentals

It will result in: 1. Have a knowledge and understanding of isolated or grid-connected electrical systems with wind and photovoltaic generation (RA1.2). To evaluate this RA, exercises are carried out on the systematic analysis of circuits with renewables, evaluation tests and laboratory practices (2 projects, midterm exam, final exam, 3 laboratory practices). 2. Be aware of the multidisciplinary context of renewable energy systems (RES) in electrical systems (RA1.4). By evaluating this RA with exams, projects, and labs, the links between electrical engineering and other industrial engineering disciplines such as electronic, thermal, mechanical, and environmental engineering are revealed. 3. Have the ability to apply their knowledge and understanding to identify, formulate and solve electrical engineering problems with RES using established methods (RA2.1). To evaluate this RA, evaluation tests are carried out and specific projects are proposed for the complete dimensioning of photovoltaic generators in various demand and solar resource scenarios; also energy calculation projects for wind turbines in many different locations. 4. Have the ability to design and carry out experiments, interpret data and draw conclusions (RA4.2). To evaluate this RA, three practices are carried out in the laboratory, two of dimensioning by means of specific SW tools from RES and one with various solar cells. This knowledge is evaluated in the exams, partial and final. 5. Have the ability to combine theory and practice to solve electrical engineering problems (RA5.2). To evaluate this RA, a series of scripts and laboratory practices are carried out in which real problems are solved, in addition to the dimensioning projects of wind and photovoltaic plants that must comply with current regulations. Also knowing the United Nations Sustainable Development Goals (SDG), and in particular SDG 7 regarding access to affordable, reliable, sustainable and modern energy for all (solar or wind in this case). 6. Necessary skills are acquired for the practice of engineering at the design and implementation level of photovoltaic systems, both for grid connection, self-consumption and isolated from the grid, designs highly required by today's society (R6).They must acquire the ability to develop a specific project in practice, from the use of device selection, use of regulations, catalogs and commercial technical documentation, to its implementation in the field.
