An Educational Platform for Cascade PWM STATCOM

Abstract:

This paper presents a training system based on low-voltage cascaded PWM STATCOM.It is intended to train the employee in power grid companies.The system is characterized by load disturbance in 380-V power grid and imaginary power compensation of transformerless cascade PWM STATCOM with star-configuration. A two-hierarchy DC voltage balance strategy is adopted to stabilize the H-bridge capacitors in the compensation procedure. Simulation and experimental waveform indicate that a 380V-20kvar cascade STATCOM with star-configuration compensate the the imaginary power shortage within 20ms.
