Digital dynamic simulation of HVDC transmission systems
Proceedings of MELECON '94. Mediterranean Electrotechnical Conference, 2002The planning, design and operation of HVDC transmission systems requires the detailed study of various options and prediction of the system performance. HVDC transmission systems described by nonlinear models are not tractable for analytical approaches. Here, the tableau approach is the method that is used for the analysis of HVDC transmission systems.

Small-signal dynamic modeling of HVDC systems
IEEE Transactions on Power Delivery, 2002This paper details the development of a linear continuous-time state model of the small-signal dynamics of a high-voltage direct current (HVDC) transmission system. The dynamics in the frequency range between 2 and 200 Hz on the DC side are of interest for the identification of possible stability problems and the design of the fastest level of ...
