In this article, the modelling and simulation results related to the dynamic performance of a multiterminal HVDC system, based on Line Commutated Converters (LCC), is presented. The four-converter HVDC system simulated operates at 500 kV. In order to evaluate its behaviour in a more realistic way, the multiterminal HVDC system was embedded into an equivalent ac network that resembles an existing high voltage system. A model to represent the ac generator dynamics (speed regulator and voltage controller), which interacts with the DC system, is also presented in the paper. The converter blocking condition, which is another HVDC operative requirement, was also simulated. From the dynamic response of the converters and ac sources obtained, it can be stated that the LCC-based multiterminal HVDC system can be a good alternative to be considered while analysing issues like planning, expansion and transmission of bulk power.

W artykule zaprezentowano modelowanie i symulację właściwości dynamicznych systemu HVDC bazującego na układzie Line Commutated Converter LCC. W celu oceny właściwości w bardziej realistycvznych warunkach system HVDC został wbudowany w odpowiednią sieć AC co przypomina istniejące systemy wysokiego napięcia. Na podstawie badań stwierdzono że wieloterminalowy system HVDC może być dobra alternatywą dla istniejących systemów.
