Abstract

Abstract:
High voltage direct current (HVDC) electric power transmission systems are
preferred, in some situations, to the common alternating current AC transmission
systems as a means for bulk transmission of electrical power. Modern form of
HVDC transmission uses, extensively, modern technology. Some AC electric power
systems, which are required to be connected together, may not be synchronized.
Therefore, they cannot be connected even if the distance between them is short.
Also, in some circumstances, it is physically impossible, or highly impracticable, to
connect them, even if they are synchronized. In such conditions, HVDC systems are
considered to be the most effective method for connecting these systems.
Therefore, in this paper investigation of the performance of HVDC systems
under different operating conditions are conducted. Models representing some actual
HVDC systems, and giving voltage profiles produced under different conditions, and
simulated using Matlab/Simulink. Corresponding computed results are obtained.
