摘　　要： 根据子系统停运对直流系统输送容量的影响,直流系统的容量模型可由各子系统容量模型串并联组合而成,这些子系统的容量模型又是元件容量模型的串并联组合,而建立元件容量模型不存在维数灾难问题,因此直流系统容量模型的建立也不存在维数灾难问题。根据累计概率和累计频率的思想建立了直流系统可靠性评估的多状态容量模型,推导了容量模型的串并联组合公式。通过这些公式可将直流系统可靠性指标的计算公式化,研究结果可用于计算直流系统可靠性指标。 According to the influence of subsystem shut-down on transmission capacity of HVDC system, the capacity model of HVDC system can be constituted by the series/parallel combination of subsystem's capacity models and these capacity models of subsystems are the series/parallel combination of components. Because there is no dimension disaster when capacity models of components are established, so in the establishment of capacity model of HVDC system there is also no dimension disaster. Based on the concept of cumulative probability and cumulative frequency, a multi-state reliability model for reliability evaluation of HVDC transmission system is established and the equations of series-parallel connection combination for capacity model are derived. By means of these equations the reliability indices of HVDC system can be calculated. The results of the author's research can be used to calculate the reliability indices of HVDC systems.
