Abstract
Abstract - In this document we will analyze the voltage disturbance swells, sags and surge or spikes. Those are the most common power disturbances capable to cause malfunction or permanent damage in some equipment. The most common disturbances are the sag and surge which consist in a short duration drop in voltage. Those disturbances should be cause by Start-up of large appliances or faults on the electric delivery system caused by accidental damage, windy weather or lighting storm. To analyze those disturbances, we will created three matlab functions to model the sag, swell and surge. Those functions will analyze by using the wavelet function. By using the wavelet transform we will obtain the necessary figures that describe the voltage disturbances mentioned before. With those descriptions we can differentiate between voltage disturbances which allow us to classify them in three classes; sag, swell or surge. The signals will be simulated by using Matlab. Key Terms - Sag, Surge, Swell, Wavelet Transform.
