| 摘要: |
| 对采用分布式馈线自动化的配电信息物理系统进行了可靠性评估。基于分布式馈线自动化的故障自愈实现原理，在传统物理系统两状态元件模型中考虑信息系统的影响，通过建立信息系统的元件和网络模型描述分布式馈线自动化的终端功能和邻域局部信息的交互过程，并由故障元件的位置定量描述在配电网发生故障时信息系统元件失效对物理系统可靠性的影响。利用序贯蒙特卡罗方法抽样，对系统进行仿真以获得计及信息系统故障的可靠性指标，对信息系统通信网络和终端2类元件进行失效分析，并探究断路器的重合闸功能在纠正故障上游因信息系统故障导致的误停电情况的可靠性影响。算例分析结果验证了所提方法的有效性。 |

| Abstract: |
| The reliability of cyber physical distribution system with distributed FA(Feeder Automation) is evaluated. Based on the fault self-healing implementation principle of distributed FA, the influence of cyber system is considered in the traditional two-state element model of physical system, the terminal function of distributed FA and the interactive process of neighborhood local information are described by establishing the component and network model of cyber system, and the influence of component failure of cyber system on the reliability of physical system is quantitatively described by the location of fault components. The system is simulated by sequential Monte Carlo sampling method to obtain the reliability indexes taking into account the fault of cyber system. The failure analysis of communication network and terminal components in cyber system is carried out, and the reliability influence of circuit breaker’s reclosing function in correcting the power outage of fault upstream caused by the fault of cyber system is explored. The analysis results of an example verify the effectiveness of the proposed method. |
