Özet:Smart grid concept is a significantly important topic all over the world. The consumers should be supplied with power sources that is as clean as possible. The quality of delivered power depends on parameters defined in various standards such as The Electrical Distribution System Supply Reliability and Quality of Electricity Regulation in Turkey. To achieve complete control on the grid, Power Quality (PQ) should be monitored and controlled at the end of the distribution system. Considering the number of the consumers in the distribution system, this is achieved by designing a stand-alone and real-time Power Quality Monitoring device, which can monitor adjacent consumers but at the same time with the lowest possible cost. In Turkish distribution system topology, there exists 12 feeders at the transformer substations at most. Hence a required monitoring system should be able to measure voltage and current phases of two sides of the transformer and current phases of the 12 feeders. The main objective of this study is to measure standard-defined power quality parameters for 64 sources in real-time with a circuit that is fitting in the smallest FPGA possible. Within the scope of this thesis, a real-time system, which may form the processing sub-system of a power quality monitoring device that is capable of measuring PQ parameters in accordance with international standard IEC 61000-4-30, is implemented on FPGA. The developed system is evaluated using synthetic test data constructed on MatLAB and the results are compared with the expected values.
