| Abstract |
A new control philosophy, utilizing both Thyristor Controlled Reactive sources (TCR), and Dynamic Power Filters (DPF), has been proposed by Enslin (1988a), in the application of fictitious power compensation. This paper shows the closed-loop control of a dynamic power filter (DPF), using an adaptive signal processing algorithm based on the cross-correlation between the voltage and current waveforms. The control strategy is based on the derivation of equivalent network parameters, calculated from digital time domain, cross-correlation signal processing techniques, implemented with the aid of a microcomputer. Practical results under quasi-dynamic operating conditions, obtained from a 15 kVA three phase dynamic power filter, are included in this paper. |
