This paper presents the simulated and experimental results of an improved shunt active power compensator (SAPC). The proposed power compensator achieves IEEE Standard 1459 compliance by using moving-window discrete Fourier transform (DFT) calculations to obtain reference currents, and a time-efficient current regulator. The current regulator is based on the analysis of the per-phase electrical model of the (APC). The main feature of the proposed current regulator is the good compromise between current control behavior and time execution efficiency. This compromise results in a low computational cost current regulator with suitable control features, which allows for the implementation of a high-frequency acquisition current control loop, including an extensive computation method based on the use of moving-window DFTs to obtain the proper reference currents with every new sample. The reference current calculations follow the power decomposition proposed by IEEE Standard 1459 for maximum efficiency in supply currents. Simulated and experimental results demonstrate that the proposed SAPC operates correctly under unbalanced and nonsinusoidal conditions. A timing performance comparison is done between the proposed current control and the dq0 technique. [-]
