Study of on-line Harmonics Monitoring of Military Power System Based on Technology of Virtual Instrument

摘要

Military power system, which core is military power station, plays an important role in modernizing equipment system. Harmonic is one of the most important standards to quality of military power system ，It can timelly reflect the power quality, ensure the safe of electric equipment and enhance the efficiency of military equipment, if harmonics can be monitored accurately. A method of an on-line harmonics monitoring system based on technology of virtual instrument is introduced. Data of voltage and current are collected by the hardware of monitored equipment which fixed in monitored station, processed, analysed, storaged and displayed by process based on LabWindows/CVI , and communications between local computer and remote computer are achieved by technology of network, and on-line harmonics monitoring of military power system is realized.
