摘要 在当前的配电网潮流计算方法中,一些算法的节点编号处理方法比较复杂,因此不适应实际配电网络运行方式的改变,同时也不利于程序的实现,另外,这些算法也没有考虑到树的存储结构对配电网潮流计算速度的影响。针对上面这些不足之处,提出了一种配电网络节点编号的方法和一种把树的非线性存储结构转化为线性存储结构的方法。还推导出了辐射状配电网潮流计算的数学模型,提出了一种新的辐射状配电网潮流计算迭代方法-前推法。经过实践的证明,所采取的辐射状配电网潮流计算方法的确具有以下各优点:收敛可靠性高、收敛速度快、每次迭代所用的时间少、占用内存少和编程简单等等。算例表明,该方法是一种实用的辐射状配电网潮流计算方法。 In the current power flow calculation for radial distribution networks, current node numbering schemes of some algorithms are relative complex. So they aren't suitable for changing the running modes of radial distribution networks and implementation of procedure;on the other hand, influences of storage structure on calculating speed of power flow calculation for radial distribution networks aren't taken into account, Against these shortcomings, the paper proposes a node numbering scheme and a method that transforms nonlinear storage structure into linear storage structure. At last, this paper brings forward a mathematical model for radial distribution networks, and proposes a novel method named forward sweeping method of power flow calculation for radial distribution systems, merits has been shown as follows: high reliability of convergence、high speed of convergence、little iterative time every time、little EMS memory and simpleness of programme and so on. Tests show that it is a practical method for power flow calculation for radial distribution networks.
