A T-Connected Transformer and Three-leg VSC Based DSTATCOM for Power Quality Improvement

  title={A T-Connected Transformer and Three-leg VSC Based DSTATCOM for Power Quality Improvement},
  author={Bhim Singh and P. Jayaprakash and D. P. Kothari},
  journal={IEEE Transactions on Power Electronics},
In this paper, a new three-phase four-wire distribution static compensator (DSTATCOM) based on a T-connected transformer and a three-leg voltage source converter (VSC) is proposed for power quality improvement. The T-connected transformer connection mitigates the neutral current and the three-leg VSC compensates harmonic current, reactive power, and balances the load. Two single-phase transformers are connected in T-configuration for interfacing to a three-phase four-wire power distribution… CONTINUE READING
