Abstract :
A real-time, closed-loop controller system for controlling active power compensators under rapidly varying load conditions is proposed. With the aid of a dedicated signal processor, using correlation algorithms, real-time, analog compensation reference signals for dynamic power compensators are generated. In order to facilitate a cost-effective compensation system, separate compensation of the fundamental reactive power component and the harmonic components is further proposed. An algorithm time of 312 mu s in a 50 Hz system is achieved, providing an effective controller system bandwidth of 1.6 kHz.<>
