【Abstract】 This paper introduced the HF power line multi_carrier channel for 500kV line relay. By analysing the Siemens power line multi_carrier and teleprotection interface characteristic for commands sending, the line relay′s requirement for teleprotection interface , and dynamic simulating testing for line relay with the Siemens power line multi_carrier and teleprotection interface, the combination operation is available.更多还原
