Abstract :
This paper presents a novel reference signal generator (RSG) for voltage-source converters (VSCs) that enables the maximization of its functionality. The proposed RSG is based on a combination of the Fortescue decomposition with recursive discrete Fourier transform. The method is characterized by computational efficiency, excellent detection accuracy, and fast dynamic response. An experimental prototype of a multifunctional VSC with the proposed RSG has been built, and experimental results are presented. The functionality of the VSC can be extended to such modes of operation as harmonic compensator, active power filter, pulsewidth modulator (PWM) rectifier, PWM inverter, balancing compensator, and STATCOM, with the update of only six coefficients in the RSG.
