【摘要】 本文阐述了利用延拓法求取ＰＶ曲线的一般算法。这种方法避开了常规牛顿－拉夫逊潮流计算中的奇异点，同时提供了自动步长设定，并对分叉点附近的数值上过渡问题利用潮流多解予以改进；此外，对负荷与发电机出力的变化方式及发电机的容量限制等问题进行了研究，并作了实例系统的计算。更多还原

【Abstract】 In this paper the application of continuationmethod in computing PV curves is first discussed. Thismethod is efficient for some systems, but there are difficulties in practical use, therefore a method is illustrated inwhich the continuation method and multiple load flow solution is combined and some further study is mentioned inpractical application.更多还原
