摘要
针对A2MC VSC-HVDC变流拓扑的可靠性问题,基于故障树及k/n(G)模型,提出其可靠性模型分析方法,并定量计算了采用各种不同功率器件时该拓扑结构的可靠度。基于可靠性贡献度的衡量指标,对这种结构进行了冗余度优化设计,使其达到要求的可靠性指标。以10kV电压等级为例进行了计算分析,结果验证了这种优化设计方法的有效性与合理性,为未来对A2MC VSC-HVDC系统的可靠性分析和设计提供参考。
The reliability of the A2MC VSC-HVDC system is mainly concerned in this paper.Analysis method is proposed based on the k-out-of-n:G model and fault Tree method,the reliability value of this topology using a variety of power devices is evaluated.Considering the reliability contribution,redundancy optimization is designed to achieve the required reliability index.Taking 10kV voltage level as an example,the calculation results demonstrate the effectiveness and correctness of this optimal design method,and provide a reference for future A2MC VSC-HVDC system reliability analysis and design.
