• 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)

• THD of the Base Case in each bus, per phase:
• 1 kV < Vn ≤ 13,8 kV : < 8%

• 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.
