Abstract
The paper deals with the problem of creation and developing of effective and perspective control means and methods for correction of voltage and current level and harmonic spectrum by means of active and hybrid correction systems in conditions of distributed generation on the base of renewable and alternative power sources. The main types of active and hybrid correction systems are presented and analyzed. The main existing means and methods of harmonic detection, compensation and signal processing are presented and analyzed. The universal control system structure for active and hybrid correction systems is proposed. The proposed control system structure and algorithm are based on existing theories of harmonic compensation and power decomposition, current physical components, p-q theory and also on modern signal processing methods. The efficiency of proposed algorithm and control system is proved by results of mathematic modeling and computer simulation. The required level of proposed control system redundancy is proved.
