Design of Power Quality Monitoring System Based on Virtual Instrument
Zhang Guo-yuan · Keisou gijutsu · 2008
In this paper,power quality monitoring system based on virtual instrument is designed after comparing several power quality monitoring instruments.A new FFT algorithm based on the wavelet transform reconstruction is used to reduce the errors caused by unstable disturbances.And network communication is achieved with Data-Socket controller.Simulation and application show that this system is reasonable and has good accuracy.
