Power quality can be represented as the variation of voltage, current and frequency in a power system.Power quality (PQ) requirement is one of the most important issues of the power companies and their consumers. With the increased use of power electronic devices, customers have become more consideration on electric Power quality.Power quality problem encompass a wide range of disturbances such as voltage fluctuations like voltage sag and swell, notch, spine transient analysis using a variety of techniques. Power quality estimation is one of the important featureswhich is automatically detected. power quality disturbances classification which requires the use of artificial intelligence techniques. In this paper, short-term application of fuzzy expert system voltage disturbances including voltage sag, swell and interrupts classification are discussed. Fuzzy expert system has been developed to set the input and output of the fuzzy rules. The system is designed to detect and the three types of short duration voltage disturbances classification.

Power quality, fuzzy control, fuzzy expert systems, feature extraction, membershipfunction.
