This paper presents a systematic approach based on eigenstructure assignment to determine the mode shape and transient response of a STATCOM utilized as an exciter for induction generators (IG). A physical control scheme, including four control loops: ac voltage, dc voltage, ac active current and ac reactive current controllers, is pre-specified for the STATCOM. A synthetic algorithm is proposed to...
Multilevel neutral point clamped inverter systems are increasingly used in load compensation applications. But, the most significant problem associated with these compensators is the capacitor voltage imbalances and drift due to DC components in the zero sequence current, resulting in degradation of tracking performance of the voltage source inverter. This paper proposes a carrier based PWM control...
A novel dynamic reactive power compensation circuit topology suitable for low voltage distribution system was proposed. The efficient compensation of unbalanced load could be realized by the structure of three-phase four-leg inverter circuit. The sinusoidal pulse width modulation (SPWM) control of inverter could ensure the low distortion of voltage and current. Besides, by the regulation of the inverter's...
