Module goal - Knowledge and skill to be achieved by students |
|
| <br> Course objective is to introduce students to specific types of failures and dangerous conditions in power system and its characteristic objects, and to principles and methods of securing selective absorption protection of those objects, in case of accidental conditions. This implies consideration not only of the protection system but also appropriate automation system, as well as selection of automation and protection system in power system. <br> Course objective is also to introduce students to realisation possibilities of characteristic functions of power system protection and automation in modern technologies and characteristics of certain technologies and systems for power system protection and automation based on those technologies. <br> Students verify acquired knowledge in laboratory exercises on real systems of power system protection and automation and by getting introduced to activities from this area on real objects in power systems, which is achieved by visiting those objects. <br> |

Didactic methods |
|
| Course is being held through three kinds of activities: lectures, laboratory work and tutorials. Fundamentals for tutorials are project assignments which students solve independently or in groups. Through laboratory work students verify acquired knowledge on real systems of protection and automation of power system. Computer simulations of very complexed structures, introduction to advanced programs of protection and automation system selection and to real objects of power system, represent structural part of laboratory activities. | |
Exams |
|
| Through the course, student gains points according to following system. <br> Attendance to lectures and tutorials: student which misses lectures and/or tutorials more than three times cannot get teacher's signature for ratification. Students are obligated to attend all laboratory hours. <br> Homework and project assignments: maximum 20 points. <br> Partial exams: two partial exams, each worth 20 points. <br> Partial exam lasts for 90 minutes. <br> Student which in the end of the course has less than 20 points has to take the course again. <br> Student which in the end of the course has more than 40 points takes final verbal examination. <br> Final verbal examination is worth maximum 40 points. To pass the course, on this examination student must have minimum 20 points. Student which has less than 20 points on final verbal examination takes verbal corrective examination. <br> Student which has gained more than 20 but less than 40 points during the course takes corrective exam. Corrective exam is valuated in the following way: <br> - written examination, worth maximum 30 points. <br> - verbal examination, worth maximum 40 points. <br> Student can take verbal corrective examination only if after passing written corrective examination has made total score of 40 or more points; this score is made of points gained through: attendance, homework, project assignments, passing partial exams and passing written corrective examination. <br> Verbal corrective examination is worth maximum 40 points. To pass the course, on this examination student must have minimum 20 points. Student which has less than 20 points on verbal corrective examination has to take the course again. <br> |
