In addition to this, the ever increasing demand for power has placed a higher requirement on power system engineers to develop efficient ways of power generation and transmission. Hence the use of High Voltage Direct Current (HVDC) for long distance transmission has been increasingly adopted over the last seven decades. Using HVDC has increased the amount of power supplied at the lowest possible line loss over long distances and for other economic reasons. In some application, HVAC has been adopted in parallel with HVDC for long distance transmission. Hence this paper looks at both configurations for the transmission of 2000MW between the Bing Coal plant and Pookland whilst considering the impact each configuration has on the rotor angle stability of the interconnected multi-machine power system. From the simulation results, the following conclusions were made. Firstly, using only HVDC transmission places a higher damping torque requirement on the generators in the Bing Coal plant. Adopting HVAC-HVDC for power transmission to Pookland reduced this requirement. Secondly, the use of HVAC-HVDC increases the terminal voltage at G3 when G4 was tripped off as opposed to case two when HVDC was used for transmission. Finally, in terms of the rotor angle stability, the use of HVAC-HVDC in parallel for transmission to Pookland is preferred as it offers better rotor angle stability to the interconnected power system.</style></abstract><issue><style face="normal" font="default" size="100%"></style></issue><work-type><style face="normal" font="default" size="100%"></style></work-type><accession-num><style face="normal" font="default" size="100%"></style></accession-num><call-num><style face="normal" font="default" size="100%"></style></call-num><notes><style face="normal" font="default" size="100%"></style></notes><custom1><style face="normal" font="default" size="100%"></style></custom1><custom2><style face="normal" font="default" size="100%"></style></custom2><custom3><style face="normal" font="default" size="100%"></style></custom3><custom4><style face="normal" font="default" size="100%"></style></custom4><custom5><style face="normal" font="default" size="100%"></style></custom5><custom6><style face="normal" font="default" size="100%"></style></custom6><custom7><style face="normal" font="default" size="100%"></style></custom7><research-notes><style face="normal" font="default" size="100%"></style></research-notes><num-vols><style face="normal" font="default" size="100%"></style></num-vols><orig-pub><style face="normal" font="default" size="100%"></style></orig-pub><reprint-edition><style face="normal" font="default" size="100%"></style></reprint-edition><section><style face="normal" font="default" size="100%"></style></section><auth-address><style face="normal" font="default" size="100%"></style></auth-address><remote-database-name><style face="normal" font="default" size="100%"></style></remote-database-name><remote-database-provider><style face="normal" font="default" size="100%"></style></remote-database-provider><label><style face="normal" font="default" size="100%"></style></label><access-date><style face="normal" font="default" size="100%"></style></access-date></record></records></xml>
