Abstract In recent years, high voltage direct current (HVDC) transmission technology has rapidly developed in power system. It can realize large capacity and long distance power transmission. HVDC and HVAC transmission technology is used to improve the power system operational flexibility. The dynamic performance of HVDC transmission line is studied. The relationship is obtained between the characteristic frequency of the transmission system and distribution parameters by calculating transfer function. The spectrum analysis of the terminal voltage is obtained. Combined with the method of ion flow field, the corona loss power is calculated. The distributed parameters are calculated by corona loss power and system characteristic frequency. The results show that this method is feasible.
