Predictive Control for Current Distortion Mitigation in Mining Power Grids

Abstract: Current distortion is a critical issue of power quality because the low frequency harmonics injected by adjustable speed drives increase heating losses in transmission lines and induce torque flickering in induction motors, which are widely used in mining facilities. Although classical active filtering techniques mitigate the oscillatory components of imaginary power, they may not be sufficient to clean the sensitive nodes of undesirable power components, some of which are related to real power. However, the u… Show more

“…This approach is inadequate for accurately assessing efficiency. The reason behind this insufficiency lies in the power electronic [26] and renewable energy systems' [27] escalating presence, which contributes to heightened harmonic levels and has a significant impact on the efficiency of transformers and electrical motors [28]. Additionally, average hourly values are not acceptable because the transformer losses are not linear [29].…”
