Artificial Intelligent Application to Power System Protection
نویسندگان
چکیده
The application of Artificial Intelligence (AI) methods in power system protection has been addressed in this paper. Particular emphasis has been put on Artificial Neural Networks (ANN) and Fuzzy Logic (FL). Several novel concepts have been introduced including ANN application to CT and CVT transients correction, fuzzy criteria signals, fuzzy settings and multi-criteria decision making for digital relays. Attached examples illustrate application of ANN and FL techniques to resolve the selected relaying problems such as the fault classification or CT and CVT dynamic error correction. Differential protection for power transformers is selected as an important example to show efficiency of the proposed concepts of FL and ANN application.

متن کاملA New Restricted Earth Fault Relay Based on Artificial Intelligence
The restricted earth fault (REF) relay is a type of differential protection which is used for detection of internal ground faults of power transformers. But, during external faults and transformer energization conditions, the probability of current transformer (CT) saturation increases. Thus, the spurious differential current due to CT saturation, can lead to REF relay maloperation. In this pap...
