Abstract:
A method of protection can be used in response to a fault in a multi-terminal power transmission system that includes a first transmission line section connecting a first terminal to a transmission line junction, a second transmission line section connecting a second terminal to the transmission line junction and a third transmission line section connecting a third terminal to the transmission line junction. The fault being located in one of the first, second or third transmission line sections. The section having the fault can be determined based on a number of calculations and other factors and a switching device can be controlled according to the identification of the section having the fault.
