This paper investigates the application of a GTO voltage source inverter in a two-terminal HVdc link, which is fed at the sending end by a line-commutated rectifier. This type of HVdc link may be applied when power transfer is predominantly unidirectional, especially to a weak ac system. The investigations are based on analytical studies and digital time-domain simulations with the Electro-Magnetic Transient program for DC systems (EMTDC). Control method and protection requirements are studied, together with dynamic behavior of the system following disturbances, e.g. dc fault, ac fault, start-up etc. The studies are aimed at exhibiting the technical feasibility of the proposed HVdc scheme. Need for further studies is pointed out when necessary.
