Analysis and Improving Reliability Indices of VSC-HVDC transmission system tapped by a VSC- station
نویسنده
چکیده
During the last three decades, reliability analysis of power systems considering transformers, breakers, transmission lines, and generators failure has been widely applied. This analysis has been done especially in the generation and transmission levels and is mainly restricted to high voltage alternating current (HVAC) systems. HVDC transmission systems are becoming increasingly popular when compared to conventional AC transmission. HVDC voltage source converters can offer advantages over traditional HVDC current source converter topologies and as such it is expected that HVDC-VSCs will be further exploited with the growth of HVDC transmission. In this paper, a comprehensive detailed reliability model of VSC-HVDC transmission system is developed, various reliability indices are calculated at the load point of the system and the impact of the VSC tapping station on these indices are illustrated.
