Many practical factors , such as effects of line fuses protection , disconnected switches , scheduled maintenance , spare electrical source , spare transformers in distribution system , are considered in the assessment arithmetic . in the assessment , it is more practical that low - voltage power system is equivalent to an element on the lateral section of mid - voltage system . especially , the minimal cut - sets are divided into direct cuts and indirect cuts , which makes the effects of elements in cuts on system more legible and exact 算法考虑了分支线熔断器保护、隔离开关、计划检修、备用电源、有无备用变压器的影响,将低压系统等效为中压系统分支馈线上的一个等效元件进行评估,使得该方法更符合实际,特别是,将最小割集分为直接割集和间接割集,使割集元件的影响更加清晰准确,并以c + +语言编制了计算软件。
