Abstract

一种获取直流电力网潮流的等量电导补偿型全局线性对称方法，首先根据直流电力网中的节点负荷参数和节点电源参数建立节点注入功率关于节点平移电压的等量电导补偿型全局线性关系式(101)；然后根据等量电导补偿型全局线性关系式和功率平衡节点编号建立直流电力网中潮流的等量电导补偿型全局线性对称模型(102)；再根据等量电导补偿型全局线性对称模型，利用M‑P逆矩阵建立全网节点平移电压关于非功率平衡节点注入功率的等量电导补偿型全局线性对称矩阵关系式(103)；最后根据等量电导补偿型全局线性对称矩阵关系式，计算直流电力网中各节点的电压值和各支路传输功率值(104)。该方法计算量小、无收敛问题，而且在直流电力网运行状态大范围变化时精度高。
