Abstract

For a long time, the application of power electronic devices and the access of new energy have affected the power quality of power lines. With the high proportion of photovoltaic and other new energy access recently, the power quality level of power grid will be greatly affected. Electric energy measurement may be affected by various factors in this new environment, which is an important part to ensure the fairness and justice of electric energy transaction. Firstly, the possible power quality problems caused by the high proportion of new energy access are analysed; Secondly, the theoretical effects of harmonic, voltage and frequency deviation, voltage fluctuation and flicker, three-phase imbalance on electricity meters are also studied; Finally, the influence tests of each index are developed to verify the influence of power quality on electricity meters.
