摘要：

In order to solve the distributed parameters measurement problem of HVDC transmission lines, we proposed the distributed parameters model and measured impedance parameters by the two-phase power resource system while the boundary conditions for the end of transmission lines were open circuit or short circuit to the earth. Furthermore, the maximum relative error with the different frequency interfering signals is 1.89% for the equivalent length 1 000 km of HVDC transmission lines. Moreover, the proposed method has been applied to the UHVDC transmission lines, grounding polar transmission line for Puer-to-Guangdong project and double circuit HVDC transmission lines on the same tower for Niuzai-to-Guangdong project, the measurement results demonstrate that coupling parameters are less than the self-parameters, the resistance and reactance of zero sequence are greater than those of positive sequence while the capacitance has opposite relationship. Therefore, the validation and feasibility of the proposed method can be verified through the transmission line experimental model and engineering practice application. ©, 2015, Science Press.
