Course Description Course Name : Harmonics in Electrical Machines Course Code : EE-674 Course Type : Optional Level of Course : Third Cycle Year of Study : 1 Course Semester : Spring (16 Weeks) ECTS : 6 Name of Lecturer(s) : Prof.Dr. MEHMET TÜMAY Learning Outcomes of the Course : Comprehends Harmonics and Sequence Components Understands Grasp of Harmonic Factors Understands Harmonic Resonance in Electrical Machines Comprehends Mitigation of Harmonics Understands Harmonic Mitigation at Source Understands Grasp of Filters, their types and positions Mode of Delivery : Face-to-Face Prerequisites and Co-Prerequisites : None Recommended Optional Programme Components : None Aim(s) of Course : This course discusses the effect of harmonics on electrical machines is a dynamic and evolving field (harmonic effects can be experienced at a distance from their source). The course derives and compiles ample data of practical interest, with the emphasis on harmonic power flow and harmonic filters. Generation, effects, limits, and mitigation of harmonics are discussed, including active and passive filters and new harmonic mitigating topologies. Course Contents : Definitions, nonlinear loads and system behavior, mathematical methods, harmonic producing networks (switched mode power converters, power electronic circuits in motor control, renewable energy production, arc-furnace, etc), distribution of harmonics in electrical machines, parallel and series resonance, adverse effects of harmonics in electrical machines, filtering of harmonics, passive and active filters Language of Instruction : English Work Place : Electrical and Electronics Engineering Department, First Floor   Course Outline /Schedule (Weekly) Planned Learning Activities Week Subject Student's Preliminary Work Learning Activities and Teaching Methods 1 Introduction to Harmonics in Electric Machines Lecture notes and resources Classic lecture and presentation 2 Investigation of Non-sinusoidal Waves Lecture notes and resources Classic lecture and presentation 3 Basşc Concepts of Harmonics Lecture notes and resources Classic lecture and presentation 4 Non-linear Elements Lecture notes and resources Classic lecture and presentation 5 Elements that Producing Harmonics Lecture notes and resources Classic lecture and presentation 6 Problems Caused by Harmonics in Power Systems Lecture notes and resources Classic lecture and presentation 7 Effects of Harmonics on Elements Lecture notes and resources Classic lecture and presentation 8 Midterm Examination Midterm Examination Preparation Written Examination 9 Resonance Effect in Harmonics Lecture notes and resources Classic lecture and presentation 10 Limitation of Harmonics in Electrical Machines Lecture notes and resources Classic lecture and presentation 11 Harmonic Standards Lecture notes and resources Classic lecture and presentation 12 Harmonic Filtration Lecture notes and resources Classic lecture and presentation 13 Position of the filter Lecture notes and resources Classic lecture and presentation 14 Types of Filters Lecture notes and resources Classic lecture and presentation 15 Filter Applications in Electrical Machines Lecture notes and resources Classic lecture and presentation 16/17 Final Examination Preparation for Final Examination Written Examination   Required Course Resources Resource Type Resource Name Recommended Course Material(s)  Power System Harmonics, A.A.
