The course is completed by passing the final exam. The grade can be upgraded by means of the offered homeworks.


The number of nonlinear loads (e.g. computer devices and electric drives) increases due to increased use of power electronics. It is estimated, that approximately 70 % of all generated power is going though power electronic device nowadays and the percentage will increase to be 80 % after 20 years. The nonlinear loads cause power quality problems, e.g. voltage and current harmonics and unbalance. In addition, nonlinear loads do not work properly themselves if the power quality problems occur in the grid. Therefore, the power quality devices based on power electronic converters are created to solve these problems. The objective of the course is to provide an understanding of power quality problems and related standards. The students will achieve an understanding of passive and active power quality compensation. The students will learn how to choose the suitable compensation method to different applications. In addition, the students will learn how the FACTS devices are controlled.
