Power quality implications associated with a series FACTS controller

A likely candidate for a series controller is the inverter based static synchronous series controller (SSSC). A possible application of a SSSC is to achieve an increase in power transfer in a meshed transmission system. It is shown that the SSSC control strategy affects power quality related issues such as voltage fluctuation and harmonic voltage distortion. The work presented gives an overview of the power quality issues to be considered when applying a SSSC and selecting a suitable control algorithm.
