摘　　要：为改善用于配电系统潮流计算的前推回代法,提出一种与节点编号无关的前推回代方法,采用类似于数字信号处理(digital signal processing,DSP)技术中的并行流水线技术和单片机的中断等待技术,称为并行中断等待法。用一个算例说明所提方法的计算效率和收敛性,同时与几种现有的方法如基于分层法的前推回代方法、常规的牛顿-拉夫逊法、两种改进的牛顿法即下山算法和Broyden算法进行比较。算例计算结果表明,所提方法在收敛性和计算效率方面更为优越。The back/forward sweep method is specially developed for load flow computation in distribution systems. Its convergence and computational efficiency are usually good, but there is still some space to improve. Given this background, an effort is made to develop a new back/forward sweep method accommodating arbitrary numbering of nodes. In the proposed approach, an algorithm similar to the parallel-stream technique in digital signal processing （DSP） and the interruption-waiting technique in single chip microcomputers is developed and named as the parallel and interruption-waiting method. A case study is served for demonstrating the convergence and computational efficiency of the proposed method, and for comparisons with several existing methods such as the conventional Newton-Raphson method, two modified Newton methods and the existing hierarchical back/forward sweep method. It is shown by simulation results that the proposed method is superior to the others in terms of the convergence and computational efficiency.
