Behaviour of Mechanically Switched Capacitors with Damping Network (MSCDN) during Energization

Abstract

Reactive  Power  Compensation  is  becoming  in-creasingly  important,  as  more  and  more  conventional  generation  is  replaced by dispersed energy sources, which do not contribute to  voltage  stability  in  the  transmission  grid.  The  Mechanically  Switched Capacitors with Damping Network (MSCDN) is a cost-efficient  solution,  combining  reactive  power  compensation  and  harmonic mitigation. In this paper, the MSCDN is analysed with respect to its design parameters to determine the electrical stress on  the  components  during  energization.  The  analysis  is  done  in  Laplace  and  frequency  domain,  as  well  as  through  time-domain numeric simulation.
