Abstract:
The proposed 500 MW interconnection is the first
DC power transmission link that is planning to connect in
between Sri Lankan and Indian AC transmission networks.
Proposed AC-DC system integration should determine the
asymptotic stability of transmission network in both countries.
Reliability can be improved by properly selecting system
configurations. Properly selected DC & AC system parameters
determine the stable performance at steady state and at
perturbed conditions. This paper presents the modelling analysis
of proposed HVDC interconnection for selected physical
configurations. The interconnection was modelled using
PSCAD/EMTDC software and simulated under the steady state
conditions and perturbed conditions. The analytical results were
verified using time domain simulations.
