一种获取直流电力网潮流的均衡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和参考节点编号建立直流电力网中潮流的均衡电导补偿型全局线性偏心模型(102)；再根据均衡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均衡电导补偿型全局线性偏心矩阵关系式(103)；最后根据均衡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、无收敛问题，在直流电力网运行状态大范围变化时精度高。

Equilibrium Conductance Compensation Global Linear Eccentricity Method for DC Power Flow Obtainment

A global linear eccentricity method based on balanced conductance compensation for DC power flow is proposed. Firstly, a global linear relationship (101) of balanced conductance compensation for node injection power with respect to node translation voltage is established according to node load parameters and node power supply parameters in DC power network. Then, DC power is established according to the global linear relationship of balanced conductance compensation and reference node number. The global linear eccentricity model of equilibrium conductance compensation for power flow in power network (102); then, according to the global linear eccentricity model of equilibrium conductance compensation, the global linear eccentricity matrix formula (103) of equilibrium conductance compensation for the translation voltage of non-reference nodes with respect to the injection power of non-reference nodes is established; finally, the global linear eccentricity matrix formula of equilibrium conductance compensation and the translation power of reference nodes are used. Voltage value, calculating the voltage value of each node and transmission power value of each branch (104) in the DC power network, realizes the problem of small amount of calculation and no convergence, and has high accuracy when the operation state of the DC power network changes in a wide range.
