A New Vector Draft Method for Harmonic Source Detection at Point of Common Coupling
In modern power networks, the issue of power quality (PQ) is becoming very important because of the increasing of load which sensitive to current disturbances. This is mainly due to the increasing use of non-linear power electronic devices draws nonsinusoidal current and creating a current distortio...

description |
In modern power networks, the issue of power quality
(PQ) is becoming very important because of the increasing of load
which sensitive to current disturbances. This is mainly due to the
increasing use of non-linear power electronic devices draws nonsinusoidal
current and creating a current distortion. As a result
there is increasing need for PQ to be monitored to establish the
type, sources and locations of PQ disturbances, allowing remedial
measures to be taken. Consequently, harmonic is one of the most
concerned power quality disturbances. The detection of harmonic
source is necessary for power quality strategy development. This
paper introduces a new single-point measurement method to
estimate the harmonic source by using phase spectrogram (PS)
and frequency spectrogram (FS) based on a vector draft method.
A measurement at the point of common coupling (PCC) with
harmonic distortion is done by simulation via PSCAD. Then
PSCAD’s data are analyzed by using spectrogram in MATLAB.
To be precise, voltage and current waveforms are normalized with
fundamental magnitude respectively. Next, the normalized voltage
and current are plotted on the vector draft to estimate the
perpendicular point between the vectors. The center point of the
normalized voltage is the boundary between downstream and
upstream. The harmonic source can be detected base on the
perpendicular point’s location that fall on the particular region.
The comparison between actual and power direction result have
been conducted. Finally, the proposed method is similar with the
actual result and more truthful than power direction method. |
