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.
