Güç sistemlerindeki harmoniklerin ölçülmesi analizi ve bunların etkileri

Identifying problems in an electrical network before any extensive damage occurs is advisable for any power system. Not only does monitoring of power quality necessary for the maintaining accurate operation of sensitive equipment, it also ensures that unnecessary energy losses in a power system are kept at a minimum which lead to more profits. This thesis seeks to identify most popular power quality problem, harmonics in the distribution System located in zmir. For the problems identified, recommendations are suggested to improve the power quality. The voltage harmonics caused by converter circuits of large motors is investigated with measured data from the distribution system and simulatedusing MATLAB/Simulink to observe the extent of the harmonic throughout the system. Results of the thesis include the total harmonic voltage distortion of the distribution system is being within IEEE standards, and a correct mitigation technique available for the identified harmonic problem if it is possible.
