Description and contextualization of the subject

The subject "Modelling of wind/current turbine driven electric generators" is intended to complete the global vision of electricity generation systems from renewable sources, taught together with the subjects studied during the frst semester in the University of Strathclyde. Focusing on the knowledge of the electricity generation converters used today for renewable energy generation, as well as those that are in the process of development for this purpose.



The dynamic models of the electric power converters will be analyzed in depth, from the synchronous generators with continuous excitation and permanent magnets (PMSG), through the squirrel cage and doubly fed asynchronous (DFIG) and the power electronic converters. The objective is to study its influence on the stability of the power system and provide the basis for the study of control algorithms, carried out in other subjects of the master.



The individual objectives are:



- To provide students with a rigorous knowledge of the electric power converters, necessary for the design and implementation of vector control schemes.

- To train students for the implementation of simulation models of the predominant electric machines in the generation of renewable energy

- Provide students with the necessary tools to analyze the stability of power systems with different types of electric power converters

- To introduce students in the process of design, adjustment and digital implementation of vector control schemes of the different converters

Learning outcomes of the subject

To select the proper model of the electric generator for offshore renewable energy production depending on the technology and type of study.



To model different electric generators for dynamic studies including it associated controllers.



To implement dynamic models of electric generators in a power system simulator software of general use.

Ordinary call: orientations and renunciation

CONTINUOUS ASSESMENT:



The subject is evaluated according to three methods:



1. Assistance, active participation in class and homework exercises: 0 - 100%

2. Group work including presentation: 0 - 35%

3. Final exam (test plus exercises): 0 - 35%



To pass the subject, a minimum global mark of 5 (pass) is needed, when the minimum mark in methods 2 and 3 is above 3.5 points. If this minimum is not achieved the final mark will be 4.5 (fail)



To renounce the continuous assesment methodology, the student must request in writing to the academic committee of the master, within a period not less than a week from the official date of the final exam established for the subject.



FINAL EVALUATION



In the event that the continuous assessment is waived, the final evaluation system will consist of an evaluation test of each block, whose weighting will be as follows:



- Theory: 50%. Indludes all the subjects studied in the lectures

- Practice: 50%. Includes an exercise similar to those solved for homework



To pass the subject, a minimum mark of 5 (pass) is needed in each block. If this is not achieved, the final mark will be 4.5 (fail)
