Abstract |
|
This paper presents a method for detection and classification of power quality disturbances using discrete wavelet transform. The power quality disturbances are generated with the help of MATLAB using mathematical relations as per IEEE Standard-1159. The investigated power quality disturbances include complex power quality disturbances. These power quality signals are decomposed using discrete wavelet transform with db4 as mother wavelet up to level 4 of decomposition. The plots related to detail coefficients and approximation coefficients are analyzed for detection of PQ disturbances. Based on the features of the plots, the presence of power quality disturbance in the signal is investigated. |
