This paper deals with two non-conventional HVDC system, that are, the Capacitor Commutated Converter (CCC) in which series capacitors are included between the converter transformer and the valves, and the Controller Series Capacitor Converter (CSCC), based on more conventional topology, in which series capacitors are inserted between the AC filter bus and the AC network. The simulation waveforms show that if these compare to conventional HVDC, these HVDC systems have many advantages in steady-state and transient performance.

Capacitor Commutated Converter HVDC system is required the small reactive power. It has the advantage of an application to the week grid because the firing angle ${\alpha}$ can be increased to a value well beyond $180^{\circ}$. In this paper, The three HVDC converter arrangements which are the CCC(Capacitor Commutated Converter) and the CSCC(Controlled Series Capacitor Convertor) and Conventional Converter are compared the dynamic character. and it find that the CCC HVDC is operating with more reliability. The simulation was conducted to the PSCAD/EMTDC.
