摘要
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 positivesequence parameters as well as calculation formulae for positive-sequence impedance and capacitance, in which the influence of distributed capacitance is taken into account, are given, and the hardware structure of the measuring system is described. Results of simulation and actual measurements show that the proposed approach is feasible.关键词
