- ok» (Great extent)

10. To what extent has the practical laboratory experiment been of help for your learning?

- eventough I have no problem of understanding the transient stability it have given me a practical knowledge of synchronisation snd simulating faults in system »
- some extent. I think it was good»
- Lab didn"t demonstrate anything. For, the idea had beed to really verify that if we are above the critical time machine losses synchronism. However in the lab it could been verified because of excesive damping. It is not logic, since it is expected that under any disturbance the machine will oscillate, but what makes different if we choose the critical time? I don"t know the reason why it coudn"t be done. If it is not possible to let the machine run out of step there should be an indicator that it really has lost synchronism.»

Genomsnitt: 3.71

- I consider that the problem is that there are too many topics to cover in this course. That is why the lecturer has to "run" to cover each topic. I consider that the course should be split in two in such a way that all the topics can be covered in detail. Reactive power control can be taught in PSO and there should be a course of just Power system stability, that covers in detail some topics that are missing, like small-signal stability, machine modeling, etc. » (Adequate)
- The topics are to many and this meant that just a brief overview of all of them was given which I didn"t like considering the high relevance of the teached topics in the Power Sytems area. The course should be splitted into 2 or even 3 courses where Stability should be taken by itself. It could be also the case for Electrical Systems Protection.» (Adequate)
- I liked this course and teaching by the professor very much» (Excellent)
- It covers alot of areas» (Excellent)

20. What should definitely be preserved to next year?

- every thing»
- lamp demonstration was really great.»
- Lab should be preserved but improved. The rest is ok.»
- lecturer,tutorial,lab,demonstration and specially digsilent project work»
- Need some more time for revision of lecture.»
- project, handouts, laboratory.»
- study visits and laboratory»
- Lectures, visits, project, and demonstration.»
- more project works.»
- Lab »
- All of them.»
- sylubus»
- The project, the Aristo demonstration.»
- Computer LAB Project»

21. What should definitely be changed to next year?

- the tutorial material on the webpage much sooner. The lecture material on the webpage much sooner. What to do in the project should be decided before it starts not after.»
- more elaboration on generators and voltage stability»
- The project could be carried out earlier in the course. So that you can start focusing on the exam the last week.»
- I would divide the whole course in two.»
- there should be talented/confident teacher for the tutorial section next year»
- the study tour to göteborg energy»
- No time for revision, since the there was class till end. Need some gap between the last class and exam.»
- tutorial teacher»
- tutorial,more study visits and tutor has to give real time examples more.»
- The tutorial problems where ok. The explanation of the solution was not very good. The project organization can be better. Finally, during the last day it seemed that we lacked time to finish the last topic and conclude the course.»
- Nothing»
- the teaching of reactive power control part»
- time before exams»
- The lab was no good. More things should be done. The study visit also should be better to a power generation center.»
- - Please replace the hand written material with material written on the computer.»

22. Additional comments

- this course was highly impressive for me»
- sometimes the tone of voice of the lecture teacher can be very flat. try making the lectures more dynamic by involving the students»
- I think it would be interesting to have a course about protections (power system protections, electric motor protections, transformer protections, etc..)»
- Power operation was perfect and I did not »
- Too many questions are asked during the classes,i think ,the tutor and lecturer should control the time.It cost us a lot of time waiting for someone to ask the simple question.Maybe they can ask after class without wasting our time.»
- I think more text handouts should be added because some handouts were not clear when I wanted to review them.»
- course is ok»
- As mentioned before, this course treats so many topics that just a breif overview is seen. It should be splitted into 2 or 3, since the topics involved are more than interesting and important in the Power Systems area.»
