The electric arc furnaces are a very large power load, determining the negative effects on the power quality (harmonics currents, unbalanced load, and reactive power). For a maximum efficiency of the power consumption it is necessary to use an automat system for control the harmonics filters, the reactive power compensation installation and the electrodes position, in order to obtain a high val...

Abstract For the two typical topologies of extra high voltage magnetically controlled shunt reactor (MCSR), this study introduces its specific wiring methods and working principles. It conducts an analysis change characteristics response core magnetic flux under different modes body. Based on PSCAD, structures are used to model body first 500 kV MCSR put into operation in a provincial power gri...

This paper proposes a new configuration for the Unified Power Quality Conditioner, which has a DC/DC converter with super-capacitors for energy storage. The proposed UPQC can compensate the reactive power, harmonic current, voltage sag and swell, voltage imbalance, and voltage interruption. The performance of the proposed system was analyzed through simulations with PSCAD/EMTDC software. The fe...

This paper outlines a new program called E-TRAN, which bridges the gap between loadflow/stability programs and electro-magnetic transients programs. It is essentially a translation program for power systems, but includes many features to avoid manual calculations (such as the automated formation of multi-port network equivalents, initialization of machines/sources in large systems, auto-routing...
