Guía docente

The Master’s course:

The main goal of the Master’s Degree in “Electrical Energy Conversion and Power Systems” (EECPS Master) is the training of qualified staff in areas related to electrical energy management, emphasizing in power systems for renewable energies. The Master presents a double approach: scientific and professional. In the scientific thread, training focuses on the design of two main applications: Electrical Power Systems and Electrical and Hybrid Traction Systems. On the other hand, in the professional thread, training is focused on the management of electrical energy. Thus, the subjects of this thread have been designed attending to two main issues, such as the management of energy in large consumers and the generation and transmission of electrical energy in a liberalized market. Three main lines have been considered as keystones in the Master:

  • Electrical Power Systems
  • Electrical and Hybrid Vehicles
  • Energy Efficiency and Renewable Energies

The second semester:

The second term offers several compulsory courses for all the students. These subjects will promote the acquisition of the common skills of the Master. This term includes a subject called "Lab", designed to develop and build a functional experimental prototype based on the theoretical knowledge acquired during the first two semesters. The work done in this subject will serve as a starting point for the Master’s Thesis.

The subject:

This subject integrates different skills gained or reviewed in the previous term, and includes new contents. Power quality concept is introduced and the different disturbances are thoroughly considered. Special attention is paid to the origin and consequences of these events, as well as to the available solutions. Impact of the resurgence of distributed generation is also assessed from the point of view of power quality. Finally, power quality monitoring and benchmarking is considered.

The subject is included in the second module of the master, called “common technologies”. Other subjects, such as Flexible AC transmission systems and HVDC, will deal with the concepts introduced in this course during the third term of the Master.

The students must certify that they have passed basic skills and competences in power electronics, power plants, electric machines and control systems and automation. This can be either accomplished at his/her incoming student profile and CV or, if not covered there, by passing the related subjects of the first semester.

Regular assessment: 

The evaluation systems used in the subject, as well as the percentages assigned to these evaluation system in the final qualification are presented in the following table:

Evaluation systems

Proposed percentage

 Written tests (objective tests, short answer tests  and / or test development)

40%

 Oral tests (individual, group, presentation of  topics/projects, etc.)

15%

 Works or projects

25%

 Observation Techniques (logs, checklists, etc.)

10%

 Real / Simulated Task Performance Tests

10%

The final student’s qualification will be obtained as follows.

  • The 15% of the student’s mark comes from the assessment of a mandatory group work on a given topic that will include both a report and an oral presentation during class time. Also and additional shorter individual work can be included in this section. 
  • Another 25% comes from the assessment of the deliverables corresponding to the different training sessions (that will include not only written reports but also simulations and results files in different formats).
  • Another 50% comes from an individual written test, which will be done at the end of the term. This test will be comprehensive covering all topics discussed. Taking the tests is mandatory, and a minimum mean score of 4/10 must be achieved. Both multiple choice items and short questions will appear in this exam.  
  • Finally, the 10% left comes from the rate of attendance to the different activities (a minimum of 80% is required) and the attitude demonstrated by the student during them.
