000000195 520__ $$aBasic ideas of probability and statistics with application to chosen power system protection problems are presented. Since fault appearance and parameters are of probabilistic nature, calculated distributions of selected short-circuit signals should bring great amount of information useful for protection purposes. Two examples are described how calculated statistics may be used for decision making in a fault detection and classification unit and for effective choice of optimal input signals in an ANN-based out-of-step prediction scheme. The short-circuit cases for determination of needed distributions were obtained performing extensive simulations with use of EMTP/ATP programme.
