一种面向对象的辐射状配电网潮流计算方法

基于牛顿-拉夫逊法，提出了一种直接面向支路元件对象的配电网潮流计算方法．通过建立支路元件的功率修正方程，子网络根据其内部元件公共端节点的功率平衡约束，可消去该节点，而化简成为新的元件，并得到新元件的功率修正方程．借助电路分析中化简计算的思想，通过元件的不断合并，最终可将整个网络化为单个多端元件的形式，然后回代、迭代求解潮流．该方法直接明了，通过IEEE33节点配电系统数据测试了其有效性．

An Object-oriented Method of Power Flow Calculation for Distribution Network

Based on the Newton-Raphson method, a method orienting the elements of network is proposed. In this method the power modifying equations of the branches are established. A sub network can eliminate the conjunct bus of its inner elements and be predigested into a new element due to the power balance of the conjunct bus, and get the power modifying equation of the new element. With the predigesting idea in circuit calculation, the whole system can be predigested into the model of one element with several terminals by means of the gradual combination of the network elements, then we can get the power flow results by comeback and iteration. This method is very distinct, and the power flow of IEEE 33-bus distribution system is calculated with it, the results show that this method is effective.
