A New Algorithm for Determination of Single Phase, Shant Active Filter Reference Current to Optimize Nonlinear Loads Compensation
Abstract:   (1026 Views)
Compensating a single phase nonlinear load in many of critical applications is worth to pay attention. Non-sinusoidal current consumption in these loads would cause power quality deterioration in PCC. This should be compensated using an active filter. In an active filter, instantaneous current would be decomposed to active and reactive components. Active filter capacity deeply depends on the peak value of its supplied current. This is usually reactive component of load current. Classical theories are just for steady state analysis and modern theories are used for determining active filter reference current. This paper firstly introduces power analysis theories in the path of history and in classical and modern category.  Then, the paper presents a new theory which determines reference current for single phase active filters and leads to optimization of reactive current and so filter capacity, in constant current waveform. This theory is applied to the waveforms of a deeply nonlinear, single phase load, and results are compared with existing theories. Outputs show suggested theory supremacy by %21.3 in active filter capacity.
