چکیده
With the development of technologies, demand for good quality electric power is increasing day by day. In Distributed Generation Systems (DGs), can cause serious problems such as sensitive equipment's malfunction, temperature riseof machines. Therefore, detection events in system more important to take further actions. The existing classification methods have high computational time with low accuracy. order overcome this problem, paper presents Discrete Packet Wavelet Transform-Kalman filter based Adaptive Neuro-Fuzzy approach identification and PQ events. proposed method classifies better accuracy, less convergence error prediction. results show that has performance compared methods. Implemented tested using MATLAB it provides accuracy when systems Transform Fuzzy Logic System Fourier Artificial neural networks etc..
