摘要：

A new control philosophy, utilizing both thyristor-controlled reactive (TCR) sources and dynamic power filters (DPF) has been proposed by Enslin and Van Wyk [91 in the application of fictitious power compensation. This paper shows the closed-loop control of a 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, which are calculated from digital time domain cross-correlation signal processing techniques and implemented with the aid of a microcomputer. Practical results under quasidynamic operating conditions obtained from a 15-kVA three-phase dynamic power filter are included in this paper. © 1990 IEEE
