Electrical power quality monitoring and analysis of synchrotron radiation facility

The purpose of this paper is to monitor and analyze the power quality of NSRRC's synchrotron radiation accelerator. The monitored parameters include power demand, active and reactive power, power factor, harmonic distortion, three-phase imbalance, voltage sag, power frequency and voltage fluctuation. The acquired data are displayed in trend chart and compared with relevant standards. The compared results show they meet the standard limits. Electrical engineers can analyze the observed data and conduct predicted maintenance for preventing system faults.
