Abstract :This paper presents a performance comparison insert ignore into journalissuearticles values(the focus of numerical simulation); of traditional simulation insert ignore into journalissuearticles values(TCS,TSE); with an optimal step time simulator insert ignore into journalissuearticles values(SOST); for large HVdc systems.In SOST, a Detailed simulation of HVdc converter behavior has been modified to include the automatic selection of optimal integration steps, frequency-dependent effects of an ac system, ac system phase and magnitude dynamics of voltage insert ignore into journalissuearticles values(particularly weak ac systems);, control assessment and temporary over-voltage consequences. SOST, via graphical interfaces,provides fast and accurate information of electromechanical and the electromagnetic-transients behavior of a large HVdc/HVac system.Keywords : HVdc, Hybrid algorithm, Load flow, Dynamic behavior, Time domain analysis
