Study of harmonics (Tunisia)

The harmonic analysis was carried out in the Tunisian seawater desalination plant. Through the harmonic generation simulation of non-linear electronic loads such as frequency variators, uninterrupted power supply systems (UPS), inverters, etc., the harmonic limits of the system are determined in accordance with the IEEE 519 and IEC 61000-3-6.
