Assignments

The assignments will be uploaded in time on this page.

Assignment 1: Wind Data Analysis

* Assignment (PDF)
* Necessary data (Matlab and Excel format) and Matlab files
* Time for questions: See schedule.
* Hand in latest Friday, 31 January, 13.00.
* Important results and mistakes will be presented and discussed in an exercise session, see schedule.
Assignment 2: Generators

* Assignment
* Time for questions: See schedule.
* Hand in latest Tuesday, 18 February, 13.00.
* Important results and mistakes will be presented and discussed in an exercise session, see schedule.
* Key to the comments in the marked assignments:

* a) Stator, power supply, magnetic field
* b) Induction
* c) Rotor, current in short-circuit bars
* d) Magnetic fields of rotor and stator interact
* e) Interaction leads to changes in stator current
Properly explaining those important steps gained 0.5 points per step.

* Here you will find a picture that I should have shown you when we discussed how to connect the stator of an induction machine. Now, it should be clear where the current "enters" and "exits" a coil if the voltage of the specific phase is positive. E.g. if the current of phase U is positive, the current enters coil U at U and exits it on the opposite side. If the current is negative, it will be the other way round.
