摘要
论证了常用的由低电抗与电阻比值(X/R)来表述的病态支路的传统定义是含糊不清的,必须进一步把它分为两类:即低电抗型和大电阻型。典型的低电抗型就是带有串联补偿的高压输电线路。而典型的大电阻型则是具有小截面导线的低压线路。在求解潮流时,为了进行最佳补偿,提供了克服病态支路潮流计算中所遇到困难的方法,并澄清了先前含糊不清和曾导致某文献中一些错误结果的病态支路的概念。
This paper presents the evidence that the usual definition of ill -conditioned branches traditionally expressed by low reactance to resistance (X/R) ratios is ambiguous, and must be furtber divided into two categories: small reactance (X) type and large-resistance (R) type. The small-X type is typically an HV transmission line having series compensation,while the large-R type an LV route with small conductors. During the load flow solution this paper provides a method overcoming the difficulties of ill-conditioned branches in loadflow computation for optimal compensation, and also refines the concept of ill - conditioned branch,which was previously ambiguous and had led to some incorrect findings in the Literature.
