In order to accurately obtain power frequency parameters of EHV transmission lines,a software for calculating mutual inductance zero-sequence parameters of EHV transmission lines was designed.The software is based on Delphi7 platform,covering the calculations for parameters such as positive-sequence impedance,positive-sequence admittance,zero-sequence impedance,zero-sequence admittance and mutual inductance among multi-circuit mutual inductance lines.The software also enables accurate off-line calculation of parameters measured on live transmission lines.The parameter calculation method of the software is described.Simulation tests through real time digital simulator（RTDS） verifies the accuracy and reliability of the EHV power frequency parameter measurement based on the software platform.
