摘　　要：馈线自动化算法逻辑具有离散型软件的特点,同时受系统与现场终端之间的通信故障、开关设备的拒动、馈线运行方式改变等多种干扰因素的影响,可靠性问题一直是制约其大规模应用的关键因素之一。文中提出一种馈线故障定位、隔离和供电恢复算法可靠性评价的无失效测试方法,结合Bayes鉴定试验次数的选择方法确定测试样本空间,平均每个测试样本的运行结果对用户方的贡献度,可以得到算法的可靠性量化分值。最后,以某实际投运现场的智能分布式馈线自动化系统为例进行了应用,验证了所提可靠性评价方法的有效性。The feeder automation algorithm has the typical characteristics of discrete-type software.The reliability question has all along been one of the key restraining factors for large-scale application,being affected by various kinds of interference factors,including communication failures between system and site terminal unit,switch equipment refusing action,feeders changing its operation mode,and so on.This paper presents a failure-free evaluation test method for feeder fault location,isolation and restoration（FLISR） algorithm of reliability,and combines with Bayes identification test frequency selection method to determine test sample space.By averaging the test sample results on the user side of the contribution degree,the algorithmic reliability of quantitative score is obtained.Finally,an actual site of intelligence distributed feeder automation system is taken as an example for test,which verifies the effectiveness of the proposed reliability evaluation method.
