Power quality problems of an industrial zone from local harmonics to national blackout

With the increasing use of devices based on power electronics, negative effects such as harmonics have emerged in the electricity distribution networks. Due to these effects, the issue of power quality has become increasingly important due to the damage of sensitive electronic devices of industrial and end-users. Power quality problems are manifested by the faulty operation of the devices due to current and frequency changes on the consumer side. In addition, compensating energy needs from renewable energy sources (RES) increases the effects of these problems. In this study, an Organized Industrial Zone (OIZ) was modelled at the simulation environment by using its electrical network data. By examining the system, the frequently encountered power quality problems were determined and solutions were tried to be presented. The establishment of PPSs has increased rapidly in OIZs within the framework of the RES and their effects on the network have been ignored. For this reason, a real PPS modelling has been made within the scope of the thesis, and the problems encountered and solutions found after commissioning have been examined and evaluated with case studies.
