Skim kegagalan bumi unit penjana-pengubah menggunakan komponen simetri dan jelmaan wavelet-rangkaian neural buatan

The majority of electric faults are ground-faults. The effect of a single phase to ground-fault must be minimized. The ability to detect and classify the type of fault plays a great role in the protection of a power system. In this research, symmetrical component method is used to analyze the effect...
