PVA INTEGRATED UPQC FOR HARMONICS MITIGATION AND VOLTAGE PROFILE IMPROVING USING SVPWM

This article describes how a Unified Power Quality Controller is linked to a test system that has harmonics and voltage changes that induce sags and swells in the source and load voltages. The UPQC is supported by PVA, which is connected at the DC connection and feeds the grid with active and reactive electricity. Individual controllers are modeled for shunt and series converters using feedback from the source and load voltages and currents. Both converters work in tandem with the source voltage and the SRF controller using the sinusoidal PWM approach. Moreover, an MPPT is used to determine the reference current’s age. By substituting traditional sinusoidal PWM with space vector PWM, the model is further improved by lowering the harmonic content of the source voltages and currents. The design is modeled using time-varying graphs created in the MATLAB Simulink environment.
