TDLRtree索引结构在变电站仿真系统中的应用

The Application of TDLRtree Index Structure in Substation Simulation System

基于TDLRtree时空数据库索引结构来表示系统拓扑结构,避免了传统重构中重构树的复杂过程,通过对原有树变化后的遍历来代替了重构树,简化了重构的算法,提高了系统效率。变电站仿真系统的运行表明,该系统具有在线实时性的特点,动态分析式教学实现了与学生的即时互动,有效加深对数字变电站的理解,激发学生学习兴趣。

The paper describes the topology of power system based on a new TDLRtree index structure for spatio-temporal database. The algorithm avoids complex calculation in traditional restructure method. Since the algorithm traverses original changed tree instead of tree reconstructure, reconstructure method is simplified and calculation efficiency is impro,zed. The application in substation simulation system proves that the system has the characteristic of real-time and dynamic analysis, and it improves the understanding to the digital substation and inspires student＇s interest of learning.
