Adaptive Kalman Filtering in Computer Relaying: Fault Classification Using Voltage Models
作者： Adly Girgis , R. Brown
关键词:
摘要: This paper describes a new probabilistic technique for fault classification to be used in digital distance protection of power systems. The is based on an adaptive Kalman filter using voltage measurements. data each phase processed two models simultaneously. One assumes the features faulted while other has unfaulted phase. condition phase, or non-faulted, then decided from computed posteriori probabilities.
