Abstract

一种获取直流电力网功率传输系数的均衡电导补偿型对称方法，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均衡电导补偿型全局线性关系式(101)；然后根据均衡电导补偿型全局线性关系式建立直流电力网稳态的均衡电导补偿型全局线性对称模型(102)；利用M‑P逆矩阵建立全网节点平移电压关于全网节点注入功率的均衡电导补偿型全局线性对称矩阵关系式(103)；再建立支路传输功率关于全网节点注入功率的均衡电导补偿型全局线性对称关系式(104)；最后根据均衡电导补偿型全局线性对称关系式获取直流电力网的功率传输系数(105)；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。
