A Novel Controller Based on Single-Phase Instantaneous p-q Power Theory for a Cascaded PWM Transformer-less STATCOM for Voltage Regulation
In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...
متن کاملDesign , Fault Detection and Mitigation in Cascaded H - Bridge STATCOM
The concept of multilevel inverters, introduced about 20 years ago entails performing power conversion in multiple voltage steps to obtain improved power quality, lower switching losses, better electromagnetic compatibility, and higher voltage capability. The benefits are especially clear for medium-voltage drives in industrial applications and are being considered for future naval ship propuls...
متن کاملA Low Capacitance Cascaded H-bridge 7-level Statcom
This paper introduces a cascaded H -bridge multilevel converter (CHB-MC) based StatCom system that is able to operate with extremely low dc capacitance values. The theoretical limit is calculated for the maximum capacitor voltage ripple, and hence minimum dc capacitance values that can be used in the converter. The proposed lowcapacitance StatCom (LC-StatCom) is able to operate with large capac...
متن کاملSingle Dc Source Cascaded H-bridge Multilevel Inverter Using Three Phase Transformers for Three Phase Applications
This paper proposes an H-Bridge Cascaded Three phase Multilevel Inverter. The proposed three phase Cascaded Multilevel Inverter makes use of single DC source. The proposed three phase Multilevel Inverter uses series connected three phase transformers so the number of single phase transformers used in traditional three phase Multilevel Inverter can be reduced. Hence the volume of the circuit is ...
متن کاملControl Scheme of Multi Level Cascaded H - Bridge STATCOM
This paper presents a control scheme of cascaded H-bridge STATCOM in three-phase power systems. Cascaded H-bridge STATCOM has merits in point of switching losses, output harmonics, and the number of circuit components. But every H-bridge cell has isolated dc capacitors. So the balancing problem of capacitor voltages exists. Since STATCOM is often requested to operate under asymmetrical conditio...
