This paper presents an efficient wavelet and neural network (WNN) based algorithm for distinguishing magnetizing inrush currents from internal fault currents in three phase power transformers. The wavelet transform is applied first to decompose the current signals of the power transformer into a series of detailed wavelet components. The values of the detailed coefficients obtained can accurate...

electric arc furnaces (eafs) are unbalanced, nonlinear and time varying loads, which can cause many problems in the power system quality. in steel industries, the two arc furnaces often perform in parallel and stand on a single bus, which surely deteriorate the power quality. in this paper, in order to study and analyze the harmful effects of parallel operation of eafs, first, a three phase arc...

this paper presents a grid connected photovoltaic system, which acts as both power generator and active power filter (apf), based on flying capacitor multicell (fcm) converter. increase in the number of output voltage levels, natural self-balancing of flying capacitors and dc link voltage and lower power rating of components are the main futures of fcm converter compared with conventional multi...

The development of industrial technology is based on electronic devices that are sensitive to power quality. Thus, the demand for high-quality and reliable supplies increasing. Voltage sag results in severe problems manufacturing process quality-sensitive loads. When a fault occurs multi-ground distribution system, magnitudes current voltage faulted nonfaulted feeders become high. Hence, instal...

The inrush currents of transformers are among the main causes which compromise performance protection relays in practice. Therefore, discrimination between and faults is very important. A new technique proposed this paper to distinguish internal fault other normal transient conditions (such as current). Accordingly, a operational characteristic defined for feature extraction classification inst...

Integration of wind energy resources into the grid creates several challenges for power system dynamics. More specifically, Type-3 turbines are susceptible to subsynchronous control interactions (SSCIs) when they become radially connected a series-compensated transmission line. SSCIs can cause disruptions in generation and result significant damage farm (WF) components equipment. This paper pro...
