Abstract

Unbalance phase current appeared in the 500kV overhead transmission line during the system commission of ± 800kV Binjin UHV DC transmission project. An inductor model of parallel lines on same tower was established for theoretical analysis. Electromagnetic transient model was also established in EMTDC/PSCAD. Both theoretical analysis and simulation result pointed that: the inappropriate overhead line arrangement of tower induces the unbalance phase current. The mechanism of unbalance phase current was revealed and optimal arrangement of parallel transmission line on same tower was given.
