中文摘要	Because of its large transmission capacity, lots of components and high failure rate, the impact of HVDC system on the reliability of power system is significant. With increase applications of HVDC systems, it is necessary to research quantitatively the reliability impact of incorporating an HVDC link in a power system. Based on the bipolar HVDC system configurations and characteristics and using fault tree analysis (FTA), the failure result of HVDC systems is divided into three kinds: monopolar total outage, bipolar total outage and capacity reduction. Frequency and duration (FD) technique is adopted to obtain a multi-state model of HVDC systems, which is embedded in the reliability evaluation software of power generation and transmission systems. Considering the influence of DC control measures on power system state analysis, the reliability evaluation model, algorithm and indices for hybrid AC/DC system an; established and corresponding software is developed. The feasibility and effectiveness of the presented algorithm and software are verified by the reliability evaluation results for hybrid 500 kV AC/DC system of South China electric power grid in the planning of 2005.
