Abstract :
In this paper, the power quality of PV system is analyzed which contains test conditions, test method and test results according to the technical rule of power quality in Q/GDW617-2011 ´Technical rule for photovoltaic power station connected to Power Grid´ and the test procedures of power quality in Q/GDW618-2011 ´Test procedures for photovoltaic power station connected to power grid´. Compare with power quality in different test environments, the DC source in laboratory and the PV module in PV station is the main reason. In addition, the improvement of inverter test is suggested in this paper.
