چکیده
Power quality monitoring has advanced to an important tool for system evaluation and solving power-related problems. As a consequence the increased amount of recorded data requires more sophisticated analysis methods. The paper proposes a system for automated recording and classification of power quality disturbances. The system features statistical classification techniques applied to a frame-based event model. Results and experiences made by a test in a low-voltage power system are presented. Keywords— Classification system, field test, power quality, power quality monitoring.

A novel method based on a combination of deep learning algorithm and fuzzy intelligent functions in order to classification of power quality disturbances in power systems
Automatic classification of power quality disturbances is the foundation to deal with power quality problem. From the traditional point of view, the identification process of power quality disturbances should be divided into three independent stages: signal analysis, feature selection and classification. However, there are some inherent defects in signal analysis and the procedure of manual fe...
