Investigations on modern self-defined extinction advance angle controller for CCC based HVDC systems

Abstract

A Modern Self-defined Extinction Advance Angle Controller is proposed in this paper and suitability of the proposed controller for a Capacitor Commutated Converter(CCC) based HVDC system is investigated. The proposed controller is dedicated at the inverter end and hence the rectifier end converter is endowed with the standard CIGRE controller. The performance of the proposed controller is investigated under different operating conditions including post fault recovery and fault mitigation. The suitability of the proposed controller for a CCC HVDC system has been checked. CIGRE benchmark controller is adopted for comparison and it has been found that the proposed controller outperforms at post fault operating conditions. PSCAD/EMTDC simulation software has been used for justification of results. © 2013 Springer-Verlag.
