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。

Lossless Eccentricity Method for Obtaining Power Transfer Coefficient of DC Power Network

A lossless eccentricity method for obtaining the power transmission coefficient of DC power network is presented. Firstly, a lossless global linear relationship (101) of injected power with respect to the translation voltage of the node is established according to the known load parameters and power supply parameters of the node in the DC power network, and then a steady-state zero of the DC power network is established based on the lossless global linear relationship and the known reference node number. Lossless global linear eccentricity model (102); Lossless global linear eccentricity model (103); Lossless global linear eccentricity matrix relation of translation voltage of non-reference node with injection power of non-reference node (103); Lossless global linear offset of branch transmission power with injection power of non-reference node (103); Lossless global linear offset of branch transmission power with injection power of non-reference node (102); Lossless global linear offset of branch transmission power with injection power of non-reference node (103 At last, the power transmission coefficient (105) of DC power network is obtained according to the global linear eccentricity relation without loss and the definition of known power transmission coefficient. This method achieves high accuracy, fast and reliable calculation, and improves the accuracy and real-time control of power network when the operation state of power network changes in a wide range.
