The Power Quality Monitoring System Based on Virtual Instrument and Configuration Software

摘要

Ship power system is an independent and complete small-scale power system, which has high requirements for power quality. In order to real-time monitoring of ship power quality, a set of power quality monitoring system is developed using virtual instrument technology and configuration software. Real data are picked by DSP, analyzed and processed by LabVIEW. Power quality including deviation of supply voltage, deviation of frequency, harmonics, three-phase voltage unbalance factor and voltage fluctuation and flicker is calculated. The key data in the power quality monitoring station are sent to the ship energy management system (SEMS), for the use of unified energy management.
