In terms of the wide application of virtual instrument technique in the power system

structure of the high voltage dynamic reactive power compensation system based on virtual instrument and CORBA to achieve the functions of dynamic reactive power compensation is presented in this paper.This system is made up of the digital monitoring instrument to achieve such functions as remote data acquisition

data processing and analysis

diagnosis and control.The digital monitoring instrument is developed to achieve the functions of hardware monitoring by LabVIEW software.In the network communication

the remote access and control between the central control station and each industrial control unit in the isomeric environment are achieved by use of CORBA technique.The quality and reliability of power supply can be effectively improved by the application of such system.Which has the very high practical value and application prospect.
