Design and Simulation of Voltage Fluctuation Rate Monitor System Based on Virtual Instrument Technology*

AbstractElectronic power is the most widely used energy, and its application degree has been a mark of country development level. This paper introduces a method of voltage fluctuation rate monitor by using virtual instrument technology. Because virtual instrument technology uses computer own hardware and design graphics procedure frame diagram software to complete, which has many advantages of the simple algorithm and fast speed, etc. Through simulating three-phase voltage of electronic power system, this paper completes voltage fluctuation rate monitor of electronic power system and electronic power quality judgment, as well as verifies accuracy of algorithm diagram procedure
