Analysis of measured power-quality results of a PV system connected to Peng-Hu power system

This paper presents the power-quality measurement results of a photovoltaic (PV) system connected to the distribution system of Peng-Hu Power System, Taiwan. The studied PV system with capacity of 70.38 kW is connected to the distribution system of 380 V through thirteen DC/AC inverters that are located at the top floor of one of the buildings of National Peng-Hu University of Science and Technology, Peng-Hu. The measured data were recorded from September 25th to October 1st, 2013 for total 7 days. The recorded results include three-phase voltages, currents, active power, reactive power, power factor, frequency, current harmonics, voltage flickers, and voltage variations. It can be clearly observed from the measured results that the power quality of the studied PV system can meet the grid code of Taiwan Power Company during the measurement period.
