Abstract

Aiming at the UHV transmission line with single-phase reclosing

a time-domain line parameters calculation method using fault recording data of non-full phase operation during reclosing is proposed. For the non-faulty lines

the positive sequence and zero-sequence parameters are calculated respectively by the equivalent model of linear mode and zero-mode central parameters. With regard to the faulty lines

the positive sequence parameters are calculated using the non-faulty phase-to-phase linear-mode parameter equivalence model. If the secondary arc is not extinguished

the faulty line zero-sequence parameters are calculated using the three-phase coupled line model. If the secondary arc is extinguished

the zero-sequence centralized parameter model is used to calculate the faulty line zero-sequence parameters. The selected calculation model is adopted to establish differential circuit equations

the voltage and current samples at both ends of the line are set as known parameters

and the least squares method is used to calculate the line parameters. Simulation results of ATP-EMTP show that the proposed method can obtain the positive sequence parameters and zero-sequence parameters of non-faulty lines and faulty lines

and a suitable model can improve the accuracy of parameter calculation. Among them

the errors of positive sequence resistance

inductance and capacitance are less than 1%

0.5% and 0.23% respectively

and the errors of zero-sequence resistance

inductance and capacitance are less than 0.12%

0.1% and 0.04% respectively.
