A flexible voltage flicker teaching facility for electric power quality education

A voltage flicker teaching facility is developed for electric power quality education. The facility consists of a single and three-phase voltage flicker generator, measurement devices, and a lamp test system. The modulation amplitudes and frequencies based on the UIE 10 Hz equivalent voltage flicker value (/spl Delta/V/sub 10/) can be arbitrarily assigned by software with high accuracy. Three experiments can be offered to students, including the introduction of voltage flicker with finite or infinite frequency components and the effect of voltage flicker on lamps. This hardware teaching facility can give students a realistic and practical concept about voltage flicker.
