In this paper, a control algorithm based on Power Balance Theory (PBT) is modified to control the DSTATCOM. A 3-leg VSC (voltage source converter) with a zigzag transformer is used as a DSTATCOM (Distribution Static Compensator) for compensation of the reactive power, harmonic currents, unbalance loads and the neutral current in three-phase four-wire distribution system. The modified PBT based control...
A three-phase four-wire DSTATCOM (distribution static compensator) based on three-leg VSC (voltage source converter) isolated with a star/hexagon transformer is demonstrated for power quality enhancement in a three-phase four-wire distribution system. The DSTATCOM is controlled to compensate the reactive power, eliminate harmonic currents, balances the load and also to mitigate the neutral current...
A three-phase four-wire DSTATCOM (distribution static compensator) based on three-leg VSC (voltage source converter) and a star/delta transformer is proposed for voltage regulation in a three-phase four-wire distribution system. The DSTATCOM is controlled to compensate reactive power, eliminate harmonic currents, balances the load and also to mitigate the neutral current. The use of star/delta transformer...
A new topology of three-phase four-wire DSTATCOM consisting of a H-bridge VSC (voltage source converter) with a star/delta transformer is proposed for power quality improvement in the distribution systems. The proposed DSTATCOM (distribution static compensator) provides the voltage regulation or power factor correction by reactive power compensation along with harmonics elimination, load balancing...
In this paper, a new topology of DSTATCOM (distribution static compensator) is proposed for power quality improvement in a three-phase four-wire distribution system. A three-leg VSC (voltage source converter) based DSTATCOM is integrated with a zig-zag transformer for the compensation of reactive power for voltage regulation or for power factor correction along with load balancing, elimination of...
