摘　　要：潮流计算、稳定分析,尤其是配电系统无功/电压控制系统中,配电网节点优化编号可有效提高计算效率,增强控制的实时性。从地区配电网AVC系统的实际需要和网络结构特点出发,提出一种基于Y-△变换的节点优化编号新方法。在节点优化编号过程中,由于当节点支路数为1时,迭代计算过程中不会产生注入元素,因此提出一种称之为消一法的节点优化编号新方法。该方法对辐射型网络,通过Y-△变换使各节点的支路数始终为1,从而保证在迭代过程中不会产生注入元素,达到理想的优化编号效果,且该方法的工作量小、程序编写简单,具有较强的实用性。Distribution system buses optimization can improve the power flow calculating efficiency and enhance real - time ability of control system. This paper is established in the demand of automatic voltage control system of region distribution system and the characteristic of network structure, proposed a new buses optimization method called as eliminating one method based on star - delta transform. Using the new method, because the branch linked with the eliminated bus is one there will not bring new injected element, the star - delta transform can assure the branch is only one for any bus. This method can achieve perfect optimization purpose and at the same time with the strongpoint of calculating load less, writing programmer simple and with receivable practicability.
