Abstract

On the occurrence of faults, balancing the grid is major requirement for large distribution power system. In many grid faults the working of Traditional Voltage Support scheme (VSS) is affected because of zero-sequence voltage. In this paper an advanced voltage support scheme is proposed to support voltage under various unbalancing conditions like under-voltage and over-voltage. This scheme, called Zero Sequence compensated voltage support scheme (ZCVS) is utilized in converter interface unit to precisely control the three phase voltages at the association point (PCC) inside security limits. This scheme compensates the zero sequence voltage and can be in resistive distribution system. Zero Sequence compensated voltage support scheme (ZCVS) combined with LAPO is also proposed which borders the active power oscillations in adjustable dc-link connected to converter to support the ac grid even under severe unbalances. The consequences of the proposed voltage support scheme and complimentary strategy are compared with traditional voltage support scheme.
