Three-level active neutral point clamped DSTATCOM with Interval Type-2 fuzzy logic controller

In this article the powerful three-level neutral point clamped (ANPC) inverter used as a distributed static compensator (DSTATCOM). The active neutral point clamped inverter has the advantages of low harmonic distortion and minimized shifting loss. The active neutral point clamped inverter is used as DSTATCOM eliminating the harmonics and the nonlinear load reactive energy. Traditionally, the differential integral controller is used to regulate the voltage and current dc connection of DSTATCOM. For comprehensive mathematical modeling of the overall system, the proportional controller requires and it is tedious process. In order to overcome the abovementioned task interval type-2 fuzzy logic controller (IT2FLC) applied DSTATCOM based on a three-level effective neutral point converter. The proposed IT2FLC is used to monitor both the DCvoltage and the current loop to improve the output of the three DSTATCOM rates. DSTATCOM's overall framework including the fuzzy logic controller built in MATLAB / Simulink. DSTATCOM's simulated response has been found to be better and better than the traditional PI controller.
