Studies of unified power quality controller and controlling signal detecting method
Sun Sheng-hong · Journal of North China Electric Power University · 2002
This paper expounds the working principle of unified power quality controller and its multi-function. Several typical detecting methods of compensating signal for voltage or current analyzed and compared. A new direct-detecting method that can be used in unified power quality controller is proposed. Calculation based on this method is more simple than others, and so the detecting speed can be improved. This paper also lists a formula that can calculate the amplitude of sine voltage instantaneously.
