Abstract

一种获取直流电力网潮流的等量电导补偿型全局线性偏心方法，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参考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偏心模型(102)；再根据等量电导补偿型全局线性偏心模型，建立非参考节点平移电压关于非参考节点注入功率的等量电导补偿型全局线性偏心矩阵关系式(103)；最后根据等量电导补偿型全局线性偏心矩阵关系式和参考节点平移电压值，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)；实现了计算量小、不存在收敛问题，且在直流电力网运行状态大范围变化时精度高。
