ANN-based Detection of OS Conditions in Power System

Rebizant, W (Institute of Power Transmission and High Voltage Technology, University of Stuttgart, Germany. (on leave from Wroclaw University of Technology, Wroclaw, Poland))


Abstract: In the paper a new neural network based out-of-step protection scheme is presented. Numerous ANNs have been trained and tested with input patterns calculated from voltage and current signals generated with use of EMTP/ATP programme. Optimal selection of decision signals for ANN feeding has been done with help of proposed statistical PDF distance indices. The OS detection/prediction efficiency was assessed for various ANN sizes and data window lengths. The impact of measurement rate on the classification results has been analysed. Wide robustness checking of developed solutions has been done against different fault types and synchronous machine ratings.
