摘　　要：利用补偿算法处理ＰＱ解耦潮流中的线路开断问题，获得了很大成功。原则上，补偿算法也能适用于牛顿潮流解，但其具体实施方法迄今未见报导。文章提出了将补偿法用于线路开断下ＮＲ潮流的实施方案，并与重新形成线路开断后雅可比矩阵的牛顿解法在ＩＥＥＥ１４、３０以及５７节点算例系统上进行了数值试验和比较。结果说明了文章所述算法的正确性和可用性。Compensation method has been successfully applied to PQ decoupled power flow solution dealing with line outage problem. Theoretically, it can also be applied to NR(Newton Raphson) power flow solution, but up to now no detailed approach was reported. This paper presents an approach to combine such a compensation method with NR power flow solution. It has been tested by IEEE 14, 30 and 57 nodes systems. The results, which are the same as those of reforming postfault Jacobian matrix method, show that the presented approach is correct and available.
