Electric Power Networks
Students will gain the basic knowledge of electric power networks and the main calculations using for dimensioning of electrical equipment. Except this, they will gain the knowledge about voltage regulation and reactive power compensation and power system stability.
- describe the main features of power networks
- explain the voltage regulation principles of power system
- apply the main calculation results for electric equipment dimensioning
- analyze and critical review of calculation results
- plan the increasing level of power system security
- estimate the power system static and dynamic stability
Forms of Teaching
Lectures are given with the use of powerpoint presentations published on the web pages. The lectures are organized through 3 cycles. The first cycle consists of 5 weeks of lectures and 1st midterm exam. Second cycle has 4 weeks of lectures and 2nd midterm exam, while 3rd cycle has 4 weeks of lectures and final exam. The lectures are given in total of 15 weeks, two hours per week.Exams
two midterm exams and final examConsultations
