OPTIMAL HARMONICS COMPENSATION IN A SEA WATER DESALINATION PLANT

Abstract

A centralized compensator is presented in this paper as an effective harmonic suppression technique based on active power line conditioners (APLCs). The basic concept is to correct the grid distortion caused by power electronics-based loads. The APLCs will mitigate the distorted current by injecting anti-harmonic currents at particular network buses. The network performance is observed and the optimal corrective signals are generated through the centralized compensator considering all buses rather than the local situations to get quasi-sinusoidal voltages with minimum APLCs actions. An approach is investigated to solve the APLCs allocation and sizing problem (AAS) based on genetic algorithm under full load conditions for a sea water desalination plant as a practical case study. The online implementation of the optimal settings is achieved using Artificial Neural Network (ANN).
