Application of Power Electronic Devices on Improving Electrical Energy Quality
In recent years,electrical power quality problem has becoming increasingly serious and it can be solved effectively by power electronics technology.This paper describes the concept of electrical power quality and the interaction of power electronic devices and power quality.In combination with the present research achievements,the operation principle and function of basis compensation device (active power filter,static var compensator and three-phase unbalance device) are analyzed in the paper,and also a prospect of it is made in the end.
