Abstract

Modeling of a VSC-HVDC system is an important step in analyzing the performance of the VSC-HVDC system. In this paper, the modeling details of the converters and the DC transmission line connected to a weak AC system are presented. The weak AC system considered is an island system comprised of synchronous generators and some passive loads. For proper functioning of the system, controllers play a very important role. The details of computing the parameters of different controllers for the system under consideration are also presented in the paper. Simulations are carried out in MATLAB/Simulink/SimPowerSystems to test the performance of the controllers for the model of VSC-HVDC system feeding power to the island system, and the results are presented.
