Abstract

一种获取直流电力网功率传输系数的无损耗偏心方法，首先根据已知的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无损耗全局线性关系式(101)；然后根据无损耗全局线性关系式和已知的参考节点编号建立直流电力网稳态的无损耗全局线性偏心模型(102)；根据无损耗全局线性偏心模型，利用逆矩阵建立非参考节点平移电压关于非参考节点注入功率的无损耗全局线性偏心矩阵关系式(103)；根据无损耗全局线性偏心矩阵关系式再建立支路传输功率关于非参考节点注入功率的无损耗全局线性偏心关系式(104)；最后根据无损耗全局线性偏心关系式和已知的功率传输系数的定义获取直流电力网的功率传输系数(105)；该方法实现了精度高和计算快速可靠，且在电力网运行状态大范围变化时提高了调控的准确性和实时性。
