摘要
A balanced conductance compensation-type global linear eccentricity method for obtaining a power flow of a direct-current power grid comprises: first, according to a node load parameter and a node power supply parameter in a direct-current power grid, establishing a balanced conductance compensation-type global linear relation about a node injection power and a node translation voltage (101); then, establishing a balanced conductance compensation-type global linear eccentric model of a power flow in the direct-current power grid according to the balanced conductance compensation-type global linear relation and a reference node number (102); then, establishing a balanced conductance compensation-type global linear eccentric matrix relation about a non-reference node translation voltage and a non-reference node injection power according to the balanced conductance compensation-type global linear eccentric model (103); and finally, computing a voltage value of each node and a transmission power value of each branch in the direct-current power grid according to the balanced conductance compensation-type global linear eccentric matrix relation and a reference node translation voltage value (104). The computing amount is small, the convergence problem does not exist, and the precision is high when the operating state of the direct-current power grid changes in a great range.
