摘要
为了使故障遍历法用于配电网可靠性评估时更快速有效,文章利用数据结构中的深度搜索方法对故障后果相同的设备进行合并,然后对合并后的最小隔离块设定可靠性参数,只需对最小隔离块进行一次枚举分析即可实现对所有隔离块的参数赋值,与常规故障遍历法相比,大大减少了设备枚举数量,同时避免了由于设备故障类型不同造成的重复枚举。实际算例证明该方法适于对复杂配电网供电可靠性进行定量评估。
To make the fault traversal algorithm faster and effective, the authors use the Depth-First Search in data structure to incorporate the equipments that cause same fault results, then the reliability parameter for the incorporated least separate unit is established, and the parameter assignment for all separate units can be implemented by enumeration analysis of the least separate unit only once. Comparing with conventional fault traversal method, the enumerated amount of equipments is evidently reduced, meanwhile the repeated enumeration caused by different types of faults occurred in the equipments can be avoided. The calculation results of actual case show that the proposed method is suit to quantitative evaluation for power supply reliability of complex radial distribution network.
