Adam, G.P. and Anaya-Lara, O. and Burt, G.M. and Finney, S.J. and Williams, B.W. and McDonald, J.R. (2009) Comparison between two VSC-HVDC transmission systems technologies : modular and neutral point clamped multilevel converter. In: IECON 2009, the 35th Annual Conference of the IEEE Industrial Electronics Society and ICELIE 2009, the 3rd IEEE International Conference on E-Learning in Industrial Electronics, 2009-09-03 - 2009-09-05, Porto.
The paper presents a detail comparison between two voltage source converter high voltage dc transmission systems, the first is based on neutral point-clamped (also known as HVDC-Light) and the second is based on innovative modular multilevel converter (known as HVDC-Plus). The comparison focuses on the reliability issues of both technologies such as fault ride-through capability and control flexibility. To address these issues, neutral point-clamped and three-level modular converters are considered in both stations of the dc transmission system, and several operating conditions are considered, including, symmetrical and asymmetrical faults. Computer simulation in Matlab-Simulink environment has been used to confirm the validity of the results.
