Abstract

A novel approach is presented for efficiently
modeling a power system which indudes pardel-connected
HVAC, and HVDC transmission systems. The proposed model
has been dehved for a system in which an AC generator is
connected to an infinite bus system through a parallel AC lie
line and a ITVDC link In addition to state-space
representation, a block diagram representation has been
formed to analyze system stability. In this new block diagram
representation, the dynamic chsractenstks of the system are
expressed in terms of a newly developed H constant. The
development of the block diagram and associated H constants
are explained. The new model is evaluated using
PSCAD/RTDS real time digital simulation. Based on this new
model, the low frequency oscillation phenomenon in pardel
AC/DC system is studied and the results are shown
