农村配电网线损的矩阵算法

Matrix Algorithm for Rural Power Distribution Network Line Losses

针对农村配电网具有配变台数较多、出线少、运行数据实时获取和非实时获取困难、全网潮流计算复杂等特点,该研究介绍了计算农村配电网线损的一种矩阵算法。该算法以将变电所出口处的月用电量按实际运行变压器的额定容量分配,通过简单的矩阵代数运算,仅需一次运算即可求出配电网网损。以辽宁省北镇市柳家变电所柳南线为例进行计算对比,结果表明该算法相对于传统算法具有计算速度快、编程简单、结果更准确等特点。

Focused on the characters of rural power distribution network, e.g., higher number of rural distribution transformers, less outgoing lines, difficulties in obtaining the operational real-time and non-real-time data and complex of calculating the power flow of the whole net, in this study a matrix algorithm of the calculating rural power loss was introduced. By this method, according to the rated capacity of transformers, the monthly electricity of the substation exit was distributed, and through simple matrix algebra operation, distribution losses can be calculated one time. With Liujia substation of Beizhen city in Liaoning province as an example, by comparing the calculations, the results showed that the algorithm had many characteristics, such as which, faster calculation speed, simpler programming and more precise results ete, compared with the traditional algorithm.
