Özet:

Power Quality (PQ) is an important issue in the operation of distribution systems. The power delivered to the consumers should be as clean as possible. Quality of power is defined in various standards or regulations such as The Electrical Distribution System Supply Reliability and Quality of Electricity Regulation in Turkey. To comply with these regulations the quality of the electrical power should be monitored and controlled at the consumer side which is at the end of the distribution system. This is achieved by designing and implementing a stand-alone and real-time Power Quality Monitoring device dedicated to the distribution system within the scope of this thesis. The PQ monitoring device, which is named Mini-PQ, processes the power signals in accordance with the international standard IEC 61000-4-30 and sends the data to a PQ monitoring center by using Power Line Communication (PLC). PLC use the existing power lines thus eliminating the need to the existing or a new local area net- work. Both hardware and software running on the Mini-PQ have been developed in this thesis work. In addition, a graphical user interface (GUI) software is developed to be used in the PQ monitoring center. Performance verification of the designed PQ monitor with field measurements are carried out and the associated results are also presented in the thesis.
