Research on an Adaptive Compound Control Strategy of a Hybrid Compensation System

This paper investigates the parallel harmonic resonance problem for hybrid compensation systems, consisting of active power filters and thyristor-switched capacitors, proposes an adaptive composite control strategy solving that may arise in practical applications systems. In practice, a system can effectively solve reactive problems, but equivalent reactance capacitor supply line form resonant circuit, which generate when excited by source at non-linear load side, affecting quality stable operation system. The employs second-order generalized integrator-frequency-locked loop (SOGI-FLL) to extract voltage point common coupling (PCC) damping current command using algorithm, adaptively adjusts parameters suppression controller through content limitation. Matlab/Simulink simulations show method achieves under complex operating conditions, thus ensuring Therefore, proposed is feasible effective.
