Abstract

Distributing a voltage to the user that ought to stay in a specific limit as stated in the standard or national grid code is the obligation of the network operator. Normally, the quality of electricity generated by the utility in a conventional power plant is excellence but when it reaches the customer's terminal, the electricity may not perfectly shaped because of the disturbances in distribution networks, transmission or any other regions. One of the main issues related to power system or power quality is harmonic disturbance which is extremely altering the shape of the sinusoidal waveform from a smooth sine wave to a distorted waveform which lead to the increment of current formation, rise of voltage per unit resistance in the neutral wire and destruction of equipment and conductors due to overheating. The recognition of harmonic source is highly crucial for power quality supervision, especially when a harmonic problem takes place in a system. In this research, the method introduced by Pyzalski and Wilkosz will be used for the identification of harmonic sources location at PCC. As a result, the location of multiple harmonic sources are recognized.
