Abstract

The study of the transient performance of an HVDC power converter using EMTP requires detailed modelling of the controls and power system elements. Furthermore, owing to the complexities associated with EMTP, considerable care has to be exercised during simulation. These requirements take on added importance particularly when the HVDC power converter is operated with a weak AC power system. This paper looks at the impact of the gate firing unit, the valve snubber in the power converter model and the initialization technique when operating a rectifier with a weak AC power system
