Transformer differential protection may be of malfunction at the emergence of inrush current, and it will affect the normal operation of the transformer. So the paper puts forward a new application of wavelet energy spectrum entropy-neural network theory in transformer microcomputer protection, in which the multi-resolution analysis of wavelet transform and information entropy technology are co...

Preventive maintenance in the transformer is performed through a differential relay protection system, and it protects from internal external faults. However, Current Transformer (CT) system mal-operates during inrush currents. CT saturates due to magnetizing currents causes false tripping of relays. Moreover, identification either current or faults needs be diagnosed. For above problem, contin...

Abstract: This paper presents a seamless transition method for a droop-controlled inverter. The droop control is suitable to make the inverter work as a voltage source in both islanded and grid-connected modes, however, the transfer between theses modes can result in a big inrush current that may damage the system. The proposed method allows the droop-controlled inverter to improve the transien...
