Abstract :
Recently, renewable energy and distributed generation (DG) are of interest for electricity grid. Besides the benefit of DG, the power qualities generated by DG have to be carefully managed and monitored because, otherwise, the unmanaged DG would cause the reliability and efficiency issues to the grid. A three-phase voltage unbalance factor (VUF) is a basic power quality in the smart grid and micro grid, which are monitored and managed by the advanced metering infrastructure (AMI) system by using metering devices such as a smart meter. In this paper, the VUF measurement in the three-phase smart meter is investigated by using a single chip solution from ADE7878 Analog Devices. The three-phase voltage unbalance is calculated and compared based on the definition of VUF defined by NEMA, IEEE and IEC standards. From experimental results, the voltage unbalance measurement in the three-phase meter is highly accurate, flexible, and low cost. Therefore, the studied VUF measurement is well applicable to the three-phase smart meter in order to monitor and manage the power quality in the smart grid and microgrid.
