Abstract :
Hybrid converter HVDC transmission is a new hybrid transmission system for connecting two AC systems. Because it uses different converters, this new configuration offers several advantages over conventional HVDC systems. This paper demonstrates the superior performance of hybrid converter based HVDC transmission systems with respect to increased stability and terminal AC voltage control. A control system is developed for the hybrid system and its dynamic performance is investigated. The hybrid system performance with emphasis on commutation failure during severe disturbances and its results is also compared with a conventional HVDC scheme
