Harmonic Analysis of PWM and SVPWM Based Shunt Compensator Using Dynamic Harmonic Domain

The extended or dynamic harmonic domain method is used to obtain harmonic Analysis during steady dynamic states for static shunt compensation (STATCOM). Firing pulses used for voltage source converter (VSC) are based on unipolar pulse width modulation and space vector pulse width modulation PWM, and SVPWMs and the simulation results obtained during steady state are validated by prototype panel experiments. The voltage and current harmonics are reduced considerably when space vector modulation is used for STATCOM VSC switching.
