Abstract :
This paper presents a prediction method for obtaining harmonic reference of distribution static synchronous compensator (DSTATCOM) control. It is a new use of adaptive predictive filter based on FIR in DSTATCOM control for harmonic suppression. Not only the time delay is successfully compensated by the prediction method, but also the algorithm is not complex compared with the normal method. Moreover, no additional hardware is needed. Realization based on digital signal processing (DSP) chip and some skills are detailed analyzed in the paper. Simulation and experimental results show the effectiveness of the proposed control.
