Reverse power data analysis and feature extraction based upon continuous wavelet transform for electric power plants

This study is focused on the investigating of a power plant generator in reverse power condition. For this purpose, reverse power data were collected from a Combined Heat and Power Plant generator protection relay. The reverse power conditions were evaluated by means of the time-frequency and time-scale methods. As a result of this evaluation, it can be said that the time- frequency and time-scale properties of the signals like current, voltage, frequency, active and reactive powers were extracted with all details.
