• STUDY OF ALLOCATION OF FILTERS FOR HARMONICDISTORTION MITIGATION IN DISTRIBUTION SYSTEMS: THE
RESULTS AND CONSEQUENCES.
• Specifics objectives:
- Analysis of the harmonic flow.
- Modelling and simulation (case study).
- Filters to be apply.
- Choice of the local to be apply.

• Harmonic Distortion are perturbation in the voltage and current wavelet
signal.
• Indicators of Harmonic Distortion are used to asses the harmonic
content in a system.
• There are the individual harmonic distortion (IHDV) and total harmonic
distortion (THDV).
• Where, Vh is the harmonic voltage of order h, V1 is the fundamental frequency voltage
and H the maximum harmonic being considered in the calculation.

• According to each country there are different standard limits to ensure a
level of quality in the supply of electricity.
• Some of these standards:
- IEEE Std. 519/2014
o (upgrade of 1992)
- PRODIST Módulo 8/2017.
o (upgrade annually)

• Cases were simulated to observe the behavior of harmonic distortions
according to the allocation of filters.
• The bus with the worst THDV was initialy choiced to receive a filter.
• Then, the filter components were calculate for this bus.
• The filter was allocate in the bus, and every bus of the system was
analized.• Cases:

• The cases were created with a “slave simulator” in MATLAB.
• This simulator provides the
THDv of each bus of the system
for each case.

• It was observed that the best results to mitigate system
average harmonic distortion did not occur with the
installation of the filter in the initial proposed buses but in
another bus which is more distant.
• This occurred as a consequence of the change of the
harmonic current flow, and this highlighted the need for
attention in choosing the buses for filters installation.

• Because of this, the precaution in the analysis is very
important. Considering only the worst bus in terms of power
quality, may be a mistake, the total system must also be
considered.
• The development of new methods for the solution of
problems in power quality area is quite necessary and good
for the research with new skills.
