A novel method for addressing power quality problems in a distribution system with an unbalanced non-linear load using DSTATCOMs

  • Abstract:
  • There is requirement of fast acting devices for power quality improvement due to rapidly changing nature of electric distribution. In this paper, a comparative analysis of power quality improvement in a three-phase three-wire distribution system has been observed when one distribution static compensator (DSTATCOM) is connected at the point of common coupling by a three-phase, two-winding transformer and two DSTATCOMs are connected by a three-phase, three-winding transformer. The two-winding and three-winding transformers are in star-delta and star-delta-delta configurations, respectively. The performance of the system is examined when the DSTATCOMs are operated in power factor correction and voltage regulation modes. Their performance is evaluated when various pulse-width-modulation techniques are used along with an unbalanced variable non-linear load. It has been shown that the usage of two DSTATCOMs yields power factor improvement, harmonic reduction and voltage regulation simultaneously.
