Abstract

Power quality monitors are increasingly being used to assist electric utilities in the evaluation of the present attributes of electric power so that quality improvement actions can be taken. This fact highlights the need for a new classification strategy which is capable of tracking, detecting, and classifying power-quality events. The increased amount of recorded data requires more sophisticated analysis method. In this paper, a new classification approach that is based on the threshold method is proposed and two types of disturbances only can be implemented for detection and classifying; voltage sag and swell. The data tested is the actual data from TNB transmission lines and the disturbances divided into sag, swell and combination both.
