【摘要】:该文研究揭示了配电网安全边界的形成机理。首先,定义了元件间的拓扑距离,根据N-X后两馈线是否产生电气连接以及故障后负荷转带路径的不同,将馈线联络关系归纳为3大类:N-1联系、N-2联系和无联系,并细分为7种。其次,在观测馈线来自同一主变和不同主变的两种情况下,分析了斜线边界、直线边界的产生原因,得出边界数量计算公式。最后,总结得到7种网络结构与完整安全边界二维视图的对应表,能无需仿真绘制安全域图像或解析列写边界方程,直接按网络结构查表确定安全边界的基本图像。总结发现了安全边界的形成机理和规律:当且仅当馈线联络为N-1联系时才会出现斜线边界;而直线边界总是存在。边界数由常量和变量两部分构成,斜线数常量随拓扑距离增加而减少,直线数常量则相反。
