| Abstract: | Based on the simultaneously measured data of three-phase voltages and currents at both ends of transmission line by global positioning system(GPS),an approach to measure positive-sequence parameters of HV transmission line,in which the simultaneously measured two-terminal information of voltages and currents of transmission line is used,is proposed.The procedures of measuring positive-sequence parameters as well as calculation formulae for positive-sequence impedance and capacitance,in which the influence o... |
