摘要（英）：

The invention discloses a method for determining the radio interference of a bipolar direct current transmission line, which comprises the following steps: 1, obtaining the model parameters of the transmission line: lead parameters of the transmission line and condition of leads of the transmission line; and determining the equation set of the radio interference of the bipolar direct current transmission line; 2, the method for determining the radio interference of the bipolar direct current transmission line comprises the steps of establishing model of the radio interference of the bipolar direct current transmission line; determining the equation set of the radio interference of the bipolar direct current transmission line; determining the central unknown quantity of electric charge of split leads; determining position of equivalent charge and quantity of electric charge in the split leads; and determining the radio interference of the bipolar direct current transmission line. The invention can determine the radio interference of the direct current transmission line and judge that the radio interference of the direct current transmission line should not be greater than 55dB (muV/m) in good weather. The method of the invention can be used for design, operation and modification works of the bipolar direct current transmission line.
