A power quality prediction system

This paper describes two hardware prototypes and estimation schemes for det ermining the parameters of a simple, physically based, point-of-use electri c utility model using transient measurements. Parameters of the utility mod el are estimated using data collected by the prototypes. Frequency-dependen t effects observed in previous work in this area are modeled. Performance o f the techniques given is demonstrated by comparison of measured and predic ted line voltage distortion during current transients created by several lo ads.
