Abstract

The inherent voltage support in voltage-source converters (VSCs) which form a back-to-back VSC-HVDC asynchronous link can increase the power transmissibility by a factor of 1.68 if the installation is sited at the midpoint of the radial AC transmission line. The figure of 1.68 is the limit set by the ´transient stability´ which is reached by simulations using HYPERSIM, a real-time digital simulator. The transmission line is modelled by the telegraph equations. The hydraulic turbine, speed governor, generator, field-excitation system, power-system stabiliser (PSS) and transformers are modelled in detail.
