Load Flow Algorithm for Distribution Network Based on Centralized Meter Reading System

应用中压集抄系统充分的量测数据,首先研究了所有测量节点数据均已知状态下的潮流计算方法。根据网络结构列写节点电流方程,通过矩阵变换消去中间变量,把传统潮流非线性问题简化为一组线性方程。其次,研究了网络中缺少某些观测点的潮流计算方法。应用文献[15]中给出的测试系统算例对2种算法进行测试,验证了所提算法的正确性及有效性。

By use of the measured data of centralized meter-reading system for medium voltage power network, firstly a load flow algorithm is researched under the condition that all data of measured nodes are known. In this algorithm according to network structure nodal current equations are listed; then the intermediate variables are eliminated by matrix transform, so traditional nonlinear problem of load flow is reduced to a set of linear equations to find the solution. Secondly, another load flow algorithm is researched under the condition that some observation points in the network are absent. By means of the testing system given in reference [ 15], the two calculation methods are tested. Testing results prove that the proposed methods are correct and effective.
