| 摘 要： | 提出了用数学的方法——最小二乘法的拟合来求取配电系统中架空线路的故障率，即用某一个特定的物理量（自变量）去描述暴风天气、暴雨天气、冰雪天气、高温天气、地基等影响因素，则线路故障率（因变量）可以表示成关于各个因素物理量的函数。根据各因素的历史统计数据，分别进行故障率的最小二乘法拟合计算，计算结果证明，由最小二乘法拟合计算的各因素故障率的绝对误差值非常小。 |
| 关 键 词： | 配电系统 可靠性参数 最小二乘法 故障率 |

| Abstract: | The mathematic method of least square theory is proposed to obtain the fault rate of overhead lines in distribution system,i.e.describing such influencing factors as squall weather,rainstorm weather,ice and snow weather,high-temperature weather and groundwork by a certain given physical quantity(independent variable),and expressing the fault rate of line(dependent variable)as the function concerning the physical quantity of each factor.According to the historical statistics of each factor,least square fitti... |
