Power quality monitoring at the industrial, commercial and educational centers of Mazandaran province and presenting the related solution

The magnetic current of the transformers harmonics, the alternating switches, the increase of usage of power electronic devices in the computers, control process, adjustable speed drives and nonlinear loads has severely monitoring of the power quality the amount of present distortions in the network has been specified for the user, then by using it can present solutions such as filter design the change of the main harmonic producing sources in the system and etc. in this paper, several samples of measurements done at different existing centers at Mazandaran network which has been measured by the advanced Agilent device, is considered. We divide the centers into industrial, commercial and educational centers, and we consider the main harmonic generating sources at each section. From the obtained harmonic spectrum by using the SIMULINK/MATLAB software, we analyze the present figure.
