The embodiments of the invention disclose a parameter measurement method for high-voltage and ultra-high-voltage direct-current transmission lines. According to the method, a direct-current transmission line model having distributed-parameter characteristics is constructed. Meanwhile, the expression of the impedance per unit length and the admittance per unit length, corresponding to the direct-current transmission line model, is established, wherein the earth resistance is involved. During the resolving process of a mathematical model, a homogeneous differential equation between the voltage and the current of the line in the boundary condition is solved to obtain a two-port power transmission line equation, wherein a telegraph equation is involved. After that, assisted by the open-circuit measurement means and the short-circuit measurement means at the end of the transmission line, the open-circuit impedance and the short-circuit impedance at the sending terminal of the transmission line are respectively measured.
