Performance characteristics of artificially commutated HVDC converter

Artificially commutated converters (ACCs) have been analysed in the past to understand their potential application to HVDC transmission systems. In this paper, the previously reported steady state ACC analysis is extended to cover the overlap range up to 120/spl deg/. Comparison of ACC with naturally commutated converters is drawn for the performance characteristics involving reactive power, dv/dt, power converter impedances and harmonics in detail which have not been reported earlier in literature to the best of the knowledge of the authors.
