摘　　要：提出一种利用区间理论计算配电系统可靠性的不确定性方法;给出了区间运算的原理;并用区间数代替元件的可靠性参数对辐射形配电网进行了可靠性评估,将评估结果与传统算法所得评估结果进行对比,表明利用区间运算得到的评估结果,将涵盖由于参数值的不确定性而造成实际系统的可靠性偏差所有可能情况。This paper presents the application of interval arithmetic in evaluating reliability uncertainty in distribution systems. The computation principle is also given. In the calculation, interval number is used instead of the component parameters. The uncertainty of all the parameters is taken into consideration. In the demonstration example, it is shown that with only one evaluation, the final interval will contain all possible solutions due to the variations in parameters.
