Mamdani Fuzzy Operator Application for Determination of Damage Type in 110 Kv Electrical Transmission Lines

The hypothesis of application of fuzzy logic for protection and automatic control of the object of electric system is considered. Types of short circuit are considered as faults in power lines. The application of fuzzy logic in automation and control of electric system will allow: to accurately recognise types of short circuit on the basis of uncertain data of disturbance parameters; to disconnect the damaged section without bringing it to the critical moment; to increase the selectivity of disconnection; to increase the speed of protection and automatic control devices. Determination or identification of short-circuit types in 110 kV transmission lines with the help of fuzzy logic will allow to protect power system from abnormal modes, as well as to avoid technical and economic losses
