| 摘 要： | 详细讨论了不精确牛顿法求解潮流方程的问题，提出带部分填充量的不完全LU分解方法是不精确牛顿法快速求解潮流的一种有效预处理方法。用结合这种预处理方法的不精确牛顿法对IEEE 118节点的电力系统潮流进行了计算，结果表明这种算法比无填充量的不完全LU分解预处理的不精确牛顿法具有较少的浮点运算次数。

| Abstract: | The problem s of power flow calculation with inexact Newton methods are discussed in detail.It is suggested that the sparse incomplete L U factorization IL U with partial fill- in is a better- preconditioned m ethod for solving power flow equations faster.Then,a serial im plem entation of the new m ethod is performed on the IEEE 118- bus system,and the numerical results show that the number of floating- point operation count of the new method is significantly less than that of the no fill- in case. |
