Module 2
Harmonics and Interharmonics
1 INTRODUCTIONTwo sources of voltage and current distortion are dealt with in this seminar: harmonics (mainly)and interharmonics. Their sources and effects, as well as possible methods of their mitigation andmeasuring are presented.
1.1 General aimsThe seminar participant should obtain information on the theoretical background of the distortedsignals analysis, sources of distortion with special regard to power electronic systems, effects of
distorted voltages and currents, methods for location of distortion sources in a power system,distortion reduction methods, measurement principles, standardization, formulating contacts, etc.Most of the lecture subject will be supplemented with laboratory experiments and exemplified byanalysis of real cases.
1.2 Target groupsThis modules target group are mainly:
end-users of equipment; designers; installers or contractor of installations; electric networks operators;
equipment sellers and services providers in the electricity sector.
2 SPECIFIC AIMS AND TOPICSThe pathway of learning consists of a 2 days course, subdivided in sections (with differentduration), with these contents and related aims.
1st
dayContents Voltage & current harmonics
Power theories in electrical circuitsPassive filters of high harmonics
Aims Supplying knowledge concerning basics of distorted signals analysis, sources ofdistortion, with special regard to power electronic systems, effects of distorted voltagesand currents, methods of locating distortion sources in a power system, passive methodsfor harmonics mitigation
2nd
dayContents Active power filter
InterharmonicsHarmonic measurementsStandardizationNeutral line and transformer sizing in the environment of distorted current and voltagesCase studies (laboratory)Contract
Aims Supplying knowledge concerning principles of measuring, standardization, formulatingcontracts. Use of the obtained knowledge to analysis and solving problems in harmonics,as well as to practical measurements in laboratory.

4 GENERAL NOTES
each day there will be two coffee breaks according to the seminar program; at the beginning of the course the lecturer will explain course aims and at the end he will verify
their fulfilment;
the course will be divided in theoretical and practical sections; at the end of the lessons, a user satisfaction survey will help the lecturer in monitoring the course
quality.
5 TEACHING METHODS
Teaching methods are summarized in three main moments:
knowledge transfer (Lesson)topics exposure by the lecturer with the help of slides and presentation of practical cases;
deepening/learning verification (Discussion)
general discussion stimulated by the lecturer (also during the lesson) to verify knowledgetransfer;
practical training, laboratory activities; group work
During all the sections, the lecturer will always attend, with teaching and/or activity coordinationduty.
6 DIDACTIC MATERIAL AND TOOLS
The didactic tools which will be used by the lecturers will be:
Blackboard
Video-projector
Notebook Microphone
The lecture room will be suitable to allow the use of all the above listed didactic tools and to enablegroup work for the attendants.
Each user will receive, during the registration, a folder containing: course program; lecture notes containing all or part of the lecture slides.
Some additional electronic tools will be available also in electronic format at: http://www.leonardo-energy.org/drupal/.The folder will also include a user satisfaction questionnaire and a knowledge test (which will beboth filled and submitted at the end of the course).
7 EXISTING KNOWLEDGE REQUIREMENTS
The following (on the basic level) shall be prerequisite for the participant:
electric circuits theory: AC circuits
electric machines
electric power engineering; power system power electronics
