An Inductive Active Filtering Method for Low-Voltage Distribution Networks

open access: yesMachines, 2021
Three-phase unbalanced and nonlinear loads aggravate harmonic problems in low-voltage distribution networks. In this paper, a hybrid inductive and active filter (HIAF) system with a Ddy converter transformer is proposed.

Harmonic minimization in the operation of static VAR compensators for unbalanced reactive power compensation [PDF]

open access: yes2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005
Phase-wise unbalanced reactive power compensations are required in distribution systems for dynamic power factor correction and terminal voltage stabilization. Shunt compensators are generally used to reduce or cancel the phase-wise unbalanced reactive power (VAR) demand and to minimize the reactive power drawn from the AC supply lines.

An algorithm for optimal sizing of the capacitor banks under non-sinusoidal and unbalanced conditions [PDF]

open access: yes, 2014
In non-sinusoidal and unbalanced systems, optimal sizing of the capacitor banks is not a straightforward task as in sinusoidal and balanced systems. In this paper, by means of qualitative and quantitative analysis, it is interpreted that the classical ...
