摘　　要：近年来,配电系统中的设备不断增加,网架结构也愈加复杂,这种现状对配电系统的可靠性评估提出了更高的要求。介绍了2种可靠性评估方法,一种是优先遍历荷载路径的序贯蒙特卡罗模拟法,该方法可以更加高效地统计出负荷点的各项可靠性指标,适用于电网结构复杂的配电系统;另一种是仿射最小路径法,该方法改进了传统的区间最小路径法,在考虑了配电系统参数不确定性的同时,提高了可靠性计算的区间精度。In recent years,the equipment in the power distribution system is increasing and the grid structure is becoming more and more complex,which puts forward higher requirements for the reliability evaluation of the power distribution system.In this paper,two reliability evaluation methods are introduced.One is sequential Monte Carlo Simulation Method which traverses the load path preferentially.This method can calculate various reliability indexes of load points more efficiently,and is suitable for the power distribution system with complex grid structure.The other is the affine minimum path method,which improves the traditional interval minimum path method and enhances the interval precision of reliability calculation based on a consideration of the uncertainty of power distribution system parameters.
