Abstract: To solve the problem that the parameters under actual operation modes may be different from the database, a transmission line parameter identification model based on phasor measurement unit data was presented to identify the line parameters. Based on field measurement data, the correlation between changes in line parameters and current and voltage was analyzed. The high correlation between the reactance parameter of actual transmission lines and current was obtained. The correlation between different transmission lines was different. Study result was helpful to enhance the accuracy of database.

Key words: parameter identification, phasor measurement unit, transmission lines, correlation, power systems, operation mode
