Comparative analysis for reactive energy measurement methodologies, under non-sinusoidal conditions in three-phase four-wire circuits
(2011-12-28)
This paper presents some methodologies for reactive energy measurement, considering three modern power theories that are suitable for three-phase four-wire non-sinusoidal and unbalanced circuits. The theories were applied ...
Eigenvalue analyses for non-transposed three-phase transmission line considering non-implicit ground wires
(2012-12-11)
This paper presents a method for analyzing electromagnetic transients using real transformation matrices in three-phase systems considering the presence of ground wires. So, for the Z and Y matrices that represent the ...

Power flow in four-wire distribution networks - General approach
(Institute of Electrical and Electronics Engineers (IEEE), 2003-11-01)
The neutral wire in most power flow software is usually merged into phase wires using Kron's reduction. Since the neutral wire and the ground are not explicitly represented, neutral wire and ground currents and voltages ...
