  Power Swing Detection and Out-of-Step Prediction Using the Equal Area Criterion

  By VIPULKUMAR JESHANKER UPADHYAY, A. S. Pandya

  Abstract: During the operating conditions, the modern interconnected power systems are more subjected sudden changes, such as faults, network changes due to line trip outs, and disconnection of a large load or of a generating plant. Such disturbances create power swing among the other generators which forces the remaining generators to adjust and settle to new stable conditions. In some cases, the swings are so large that some generators run out …

  Evaluation Algorithm for Discrimination between Fault and Power Swing Using Independent Component Analysis

  By V. J. Upadhyay, A. S. Pandya

  Abstract: The analysis of faults and disturbances in power systems is a basic requirement for a secure and reliable electrical power supply. Independent component analysis (ICA) is an efficient computational method used to find out hidden components in a set of sampled data. The basic target of ICA is to find a linear representation and relation between nongaussian data captured during disturbance, so that the components are statistically independent, or as …
