Intelligent, ANN-Based Identification System of Complex Generating Sets Operating Mode

Abstract

The effective operation of the electrical power system (EPS) protection devices is mainly determined by a correctness of generated decisions, classifying actual state of the protected object to one of the two event classes (i.e. normal or fault), which may be realized only if the following conditions are considered: the acquisition of extended information about the protected object is enabled, correct identification of the object operating mode, data processing and decision making speed, the ability of the protective system adaptation to the actual object state and its “insensitivity” to any kind of interference. On the other hand the use of digital technology allows new approach to the protected object state identification and protection functions adaptation. It may be achieved by implementing additional criteria (both measuring and logical) and by use of new computational methods, based upon artificial intelligence such as artificial neural networks (ANNs).
