Selection of suitable ANN structure for fault classification in STATCOM connected transmission line

In this paper, fast and reliable operation fault classification is carried out using energy of the detail coefficients of the phase signals. Daubechies 4 wavelet was chosen because of its success in detecting abrupt changes in power system signals. The MATLAB 7.10 version is used to generate the fault signals and verification the algorithm. A scheme is proposed for 220KV Karad to Miraj STATCOM connected transmission line in Maharashtra state (India).
