ABSTRACT:
The existing liability division
methods for harmonic pollution are either inexplicit or incomplete in physical meaning. To compensate these defects, two new methods are
proposed based on line-transferred power components in this paper. At first, all
harmonic sources are represented by ideal equivalent current source,
line current components and bus voltage components of a source are determined by
stimulation of this source with all other sources disabled. Then, the line-trans-
ferred power component owing to a source under all sources action together is determined
by the theory of line-transferred power components, and called source’s line-transferred
power component. At last, the liability of a source for line-end harmonic pollution
is divided by two methods: the ration of the source’s line-transferred active power
component to the total line-transferred power, and the ration of projection of the
source’s line-transferred complex power component to absolute value of the total
line-transferred complex power. These two methods are taken into account not only
harmonic voltage but also harmonic current in the liability division. Simulation
results show that the proposed liability division method based on active power component
is the most effective and ideal one.
